+  syntax. Find out how to use curl by reading the curl.1 man page or the
+  MANUAL document. Find out how to install Curl by reading the INSTALL
+  document.
+
+  libcurl is the library curl is using to do its job. It is readily
+  available to be used by your software. Read the libcurl.3 man page to
+  learn how.
+
+  You find answers to the most frequent questions we get in the FAQ document.
+
+  Study the COPYING file for distribution terms.

+ Creative people have written bindings or interfaces for various environments
+ and programming languages. Using one of these allows you to take advantage of
+ curl powers from within your favourite language or system.
+
+ This is a list of all known interfaces as of this writing.
+
+ The bindings listed below are not part of the curl/libcurl distribution
+ archives, but must be downloaded and installed separately.

+# The curl bug bounty
+
+The curl project runs a bug bounty program in association with
+[HackerOne](https://www.hackerone.com/) and the [Internet Bug
+Bounty](https://internetbugbounty.org/).
+
+## How does it work?
+
+Start out by posting your suspected security vulnerability directly to [curl's
+HackerOne program](https://hackerone.com/curl).
+
+After you have reported a security issue, it has been deemed credible, and a
+patch and advisory has been made public, you may be eligible for a bounty from
+this program. See the [Security Process](https://curl.se/dev/secprocess.html)
+document for how we work with security issues.
+
+## What are the reward amounts?
+
+The curl project offers monetary compensation for reported and published
+security vulnerabilities. The amount of money that is rewarded depends on how
+serious the flaw is determined to be.
+
+Since 2021, the Bug Bounty is managed in association with the Internet Bug
+Bounty and they set the reward amounts. If it would turn out that they set
+amounts that are way lower than we can accept, the curl project intends to
+"top up" rewards.
+
+In 2025, typical "Medium" rated vulnerabilities are rewarded 2,500 USD each.
+
+## Who is eligible for a reward?
+
+Everyone and anyone who reports a security problem in a released curl version
+that has not already been reported can ask for a bounty.
+
+Dedicated - paid for - security audits that are performed in collaboration
+with curl developers are not eligible for bounties.
+
+Vulnerabilities in features that are off by default and documented as
+experimental are not eligible for a reward.
+
+The vulnerability has to be fixed and publicly announced (by the curl project)
+before a bug bounty is considered.
+
+Once the vulnerability has been published by curl, the researcher can request
+their bounty from the [Internet Bug Bounty](https://hackerone.com/ibb).
+
+Bounties need to be requested within twelve months from the publication of the
+vulnerability.
+
+The curl security team reserves themselves the right to deny or allow bug
+bounty payouts on its own discretion. There is no appeals process.
+
+## Product vulnerabilities only
+
+This bug bounty only concerns the curl and libcurl products and thus their
+respective source codes - when running on existing hardware. It does not
+include curl documentation, curl websites, or other curl related
+infrastructure.
+
+The curl security team is the sole arbiter if a reported flaw is subject to a
+bounty or not.
+
+## Third parties
+
+The curl bug bounty does not cover flaws in third party dependencies
+(libraries) used by curl or libcurl. If the bug triggers because of curl
+behaving wrongly or abusing a third party dependency, the problem is rather in
+curl and not in the dependency and then the bounty might cover the problem.
+
+## How are vulnerabilities graded?
+
+The grading of each reported vulnerability that makes a reward claim is
+performed by the curl security team. The grading is based on the CVSS (Common
+Vulnerability Scoring System) 3.0.
+
+## How are reward amounts determined?
+
+The curl security team gives the vulnerability a score or severity level, as
+mentioned above. The actual monetary reward amount is decided and paid by the
+Internet Bug Bounty..
+
+## Regarding taxes, etc. on the bounties
+
+In the event that the individual receiving a bug bounty needs to pay taxes on
+the reward money, the responsibility lies with the receiver. The curl project
+or its security team never actually receive any of this money, hold the money,
+or pay out the money.

+# BUGS
+
+## There are still bugs
+
+ curl and libcurl keep being developed. Adding features and changing code
+ means that bugs sneak in, no matter how hard we try to keep them out.
+
+ Of course there are lots of bugs left. Not to mention misfeatures.
+
+ To help us make curl the stable and solid product we want it to be, we need
+ bug reports and bug fixes.
+
+## Where to report
+
+ If you cannot fix a bug yourself and submit a fix for it, try to report an as
+ detailed report as possible to a curl mailing list to allow one of us to have
+ a go at a solution. You can optionally also submit your problem in [curl's
+ bug tracking system](https://github.com/curl/curl/issues).
+
+ Please read the rest of this document below first before doing that.
+
+ If you feel you need to ask around first, find a suitable [mailing
+ list](https://curl.se/mail/) and post your questions there.
+
+## Security bugs
+
+ If you find a bug or problem in curl or libcurl that you think has a security
+ impact, for example a bug that can put users in danger or make them
+ vulnerable if the bug becomes public knowledge, then please report that bug
+ using our security development process.
+
+ Security related bugs or bugs that are suspected to have a security impact,
+ should be reported on the [curl security tracker at
+ HackerOne](https://hackerone.com/curl).
+
+ This ensures that the report reaches the curl security team so that they
+ first can deal with the report away from the public to minimize the harm and
+ impact it has on existing users out there who might be using the vulnerable
+ versions.
+
+ The curl project's process for handling security related issues is
+ [documented separately](https://curl.se/dev/secprocess.html).
+
+## What to report
+
+ When reporting a bug, you should include all information to help us
+ understand what is wrong, what you expected to happen and how to repeat the
+ bad behavior. You therefore need to tell us:
+
+ - your operating system's name and version number
+
+ - what version of curl you are using (`curl -V` is fine)
+
+ - versions of the used libraries that libcurl is built to use
+
+ - what URL you were working with (if possible), at least which protocol
+
+ and anything and everything else you think matters. Tell us what you expected
+ to happen, tell us what did happen, tell us how you could make it work
+ another way. Dig around, try out, test. Then include all the tiny bits and
+ pieces in your report. You benefit from this yourself, as it enables us to
+ help you quicker and more accurately.
+
+ Since curl deals with networks, it often helps us if you include a protocol
+ debug dump with your bug report. The output you get by using the `-v` or
+ `--trace` options.
+
+ If curl crashed, causing a core dump (in Unix), there is hardly any use to
+ send that huge file to anyone of us. Unless we have the same system setup as
+ you, we cannot do much with it. Instead, we ask you to get a stack trace and
+ send that (much smaller) output to us instead.
+
+ The address and how to subscribe to the mailing lists are detailed in the
+ `MANUAL.md` file.
+
+## libcurl problems
+
+ When you have written your own application with libcurl to perform transfers,
+ it is even more important to be specific and detailed when reporting bugs.
+
+ Tell us the libcurl version and your operating system. Tell us the name and
+ version of all relevant sub-components like for example the SSL library
+ you are using and what name resolving your libcurl uses. If you use SFTP or
+ SCP, the libssh2 version is relevant etc.
+
+ Showing us a real source code example repeating your problem is the best way
+ to get our attention and it greatly increases our chances to understand your
+ problem and to work on a fix (if we agree it truly is a problem).
+
+ Lots of problems that appear to be libcurl problems are actually just abuses
+ of the libcurl API or other malfunctions in your applications. It is advised
+ that you run your problematic program using a memory debug tool like valgrind
+ or similar before you post memory-related or "crashing" problems to us.
+
+## Who fixes the problems
+
+ If the problems or bugs you describe are considered to be bugs, we want to
+ have the problems fixed.
+
+ There are no developers in the curl project that are paid to work on bugs.
+ All developers that take on reported bugs do this on a voluntary basis. We do
+ it out of an ambition to keep curl and libcurl excellent products and out of
+ pride.
+
+ Please do not assume that you can just lump over something to us and it then
+ magically gets fixed after some given time. Most often we need feedback and
+ help to understand what you have experienced and how to repeat a problem.
+ Then we may only be able to assist YOU to debug the problem and to track down
+ the proper fix.
+
+ We get reports from many people every month and each report can take a
+ considerable amount of time to really go to the bottom with.
+
+## How to get a stack trace
+
+ First, you must make sure that you compile all sources with `-g` and that you
+ do not 'strip' the final executable. Try to avoid optimizing the code as well,
+ remove `-O`, `-O2` etc from the compiler options.
+
+ Run the program until it cores.
+
+ Run your debugger on the core file, like `<debugger> curl core`. `<debugger>`
+ should be replaced with the name of your debugger, in most cases that is
+ `gdb`, but `dbx` and others also occur.
+
+ When the debugger has finished loading the core file and presents you a
+ prompt, enter `where` (without quotes) and press return.
+
+ The list that is presented is the stack trace. If everything worked, it is
+ supposed to contain the chain of functions that were called when curl
+ crashed. Include the stack trace with your detailed bug report, it helps a
+ lot.
+
+## Bugs in libcurl bindings
+
+ There are of course bugs in libcurl bindings. You should then primarily
+ approach the team that works on that particular binding and see what you can
+ do to help them fix the problem.
+
+ If you suspect that the problem exists in the underlying libcurl, then please
+ convert your program over to plain C and follow the steps outlined above.
+
+## Bugs in old versions
+
+ The curl project typically releases new versions every other month, and we
+ fix several hundred bugs per year. For a huge table of releases, number of
+ bug fixes and more, see: https://curl.se/docs/releases.html
+
+ The developers in the curl project do not have bandwidth or energy enough to
+ maintain several branches or to spend much time on hunting down problems in
+ old versions when chances are we already fixed them or at least that they have
+ changed nature and appearance in later versions.
+
+ When you experience a problem and want to report it, you really SHOULD
+ include the version number of the curl you are using when you experience the
+ issue. If that version number shows us that you are using an out-of-date curl,
+ you should also try out a modern curl version to see if the problem persists
+ or how/if it has changed in appearance.
+
+ Even if you cannot immediately upgrade your application/system to run the
+ latest curl version, you can most often at least run a test version or
+ experimental build or similar, to get this confirmed or not.
+
+ At times people insist that they cannot upgrade to a modern curl version, but
+ instead, they "just want the bug fixed". That is fine, just do not count on us
+ spending many cycles on trying to identify which single commit, if that is
+ even possible, that at some point in the past fixed the problem you are now
+ experiencing.
+
+ Security wise, it is almost always a bad idea to lag behind the current curl
+ versions by a lot. We keep discovering and reporting security problems
+ over time see you can see in [this
+ table](https://curl.se/docs/vulnerabilities.html)
+
+# Bug fixing procedure
+
+## What happens on first filing
+
+ When a new issue is posted in the issue tracker or on the mailing list, the
+ team of developers first needs to see the report. Maybe they took the day off,
+ maybe they are off in the woods hunting. Have patience. Allow at least a few
+ days before expecting someone to have responded.
+
+ In the issue tracker, you can expect that some labels are set on the issue to
+ help categorize it.
+
+## First response
+
+ If your issue/bug report was not perfect at once (and few are), chances are
+ that someone asks follow-up questions. Which version did you use? Which
+ options did you use? How often does the problem occur? How can we reproduce
+ this problem? Which protocols does it involve? Or perhaps much more specific
+ and deep diving questions. It all depends on your specific issue.
+
+ You should then respond to these follow-up questions and provide more info
+ about the problem, so that we can help you figure it out. Or maybe you can
+ help us figure it out. An active back-and-forth communication is important
+ and the key for finding a cure and landing a fix.
+
+## Not reproducible
+
+ We may require further work from you who actually see or experience the
+ problem if we cannot reproduce it and cannot understand it even after having
+ gotten all the info we need and having studied the source code over again.
+
+## Unresponsive
+
+ If the problem have not been understood or reproduced, and there is nobody
+ responding to follow-up questions or questions asking for clarifications or
+ for discussing possible ways to move forward with the task, we take that as a
+ strong suggestion that the bug is unimportant.
+
+ Unimportant issues are closed as inactive sooner or later as they cannot be
+ fixed. The inactivity period (waiting for responses) should not be shorter
+ than two weeks but may extend months.
+
+## Lack of time/interest
+
+ Bugs that are filed and are understood can unfortunately end up in the
+ "nobody cares enough about it to work on it" category. Such bugs are
+ perfectly valid problems that *should* get fixed but apparently are not. We
+ try to mark such bugs as `KNOWN_BUGS material` after a time of inactivity and
+ if no activity is noticed after yet some time those bugs are added to the
+ `KNOWN_BUGS` document and are closed in the issue tracker.
+
+## `KNOWN_BUGS`
+
+ This is a list of known bugs. Bugs we know exist and that have been pointed
+ out but that have not yet been fixed. The reasons for why they have not been
+ fixed can involve anything really, but the primary reason is that nobody has
+ considered these problems to be important enough to spend the necessary time
+ and effort to have them fixed.
+
+ The `KNOWN_BUGS` items are always up for grabs and we love the ones who bring
+ one of them back to life and offer solutions to them.
+
+ The `KNOWN_BUGS` document has a sibling document known as `TODO`.
+
+## `TODO`
+
+ Issues that are filed or reported that are not really bugs but more missing
+ features or ideas for future improvements and so on are marked as
+ *enhancement* or *feature-request* and get added to the `TODO` document and
+ the issues are closed. We do not keep TODO items open in the issue tracker.
+
+ The `TODO` document is full of ideas and suggestions of what we can add or
+ fix one day. You are always encouraged and free to grab one of those items and
+ take up a discussion with the curl development team on how that could be
+ implemented or provided in the project so that you can work on ticking it odd
+ that document.
+
+ If an issue is rather a bug and not a missing feature or functionality, it is
+ listed in `KNOWN_BUGS` instead.
+
+## Closing off stalled bugs
+
+ The [issue and pull request trackers](https://github.com/curl/curl) only hold
+ "active" entries open (using a non-precise definition of what active actually
+ is, but they are at least not completely dead). Those that are abandoned or
+ in other ways dormant are closed and sometimes added to `TODO` and
+ `KNOWN_BUGS` instead.
+
+ This way, we only have "active" issues open on GitHub. Irrelevant issues and
+ pull requests do not distract developers or casual visitors.

+## curl cipher options
+
+A TLS handshake involves many parameters which take part in the negotiation
+between client and server in order to agree on the TLS version and set of
+algorithms to use for a connection.
+
+What has become known as a "cipher" or better "cipher suite" in TLS
+are names for specific combinations of
+[key exchange](https://en.wikipedia.org/wiki/Key_exchange),
+[bulk encryption](https://en.wikipedia.org/wiki/Link_encryption),
+[message authentication code](https://en.wikipedia.org/wiki/Message_authentication_code)
+and with TLSv1.3 the
+[authenticated encryption](https://en.wikipedia.org/wiki/Authenticated_encryption).
+In addition, there are other parameters that influence the TLS handshake, like
+[DHE](https://en.wikipedia.org/wiki/Diffie%e2%80%93Hellman_key_exchange) "groups"
+and [ECDHE](https://en.wikipedia.org/wiki/Elliptic-curve_Diffie%e2%80%93Hellman)
+with its "curves".
+
+### History
+
+curl's way of letting users configure these settings closely followed OpenSSL
+in its API. TLS learned new parameters, OpenSSL added new API functions and
+curl added command line options.
+
+Several other TLS backends followed the OpenSSL approach, more or less closely,
+and curl maps the command line options to these TLS backends. Some TLS
+backends do not support all of it and command line options are either
+ignored or lead to an error.
+
+Many examples below show the OpenSSL-like use of these options. GnuTLS
+however chose a different approach. These are described in a separate
+section further below.
+
+## ciphers, the OpenSSL way
+
+With curl's option
+[`--tls13-ciphers`](https://curl.se/docs/manpage.html#--tls13-ciphers)
+or
+[`CURLOPT_TLS13_CIPHERS`](https://curl.se/libcurl/c/CURLOPT_TLS13_CIPHERS.html)
+users can control which cipher suites to consider when negotiating TLS 1.3
+connections. With option
+[`--ciphers`](https://curl.se/docs/manpage.html#--ciphers)
+or
+[`CURLOPT_SSL_CIPHER_LIST`](https://curl.se/libcurl/c/CURLOPT_SSL_CIPHER_LIST.html)
+users can control which cipher suites to consider when negotiating
+TLS 1.2 (1.1, 1.0) connections.
+
+By default, curl may negotiate TLS 1.3 and TLS 1.2 connections, so the cipher
+suites considered when negotiating a TLS connection are a union of the TLS 1.3
+and TLS 1.2 cipher suites. If you want curl to consider only TLS 1.3 cipher
+suites for the connection, you have to set the minimum TLS version to 1.3 by
+using [`--tlsv1.3`](https://curl.se/docs/manpage.html#--tlsv13)
+or [`CURLOPT_SSLVERSION`](https://curl.se/libcurl/c/CURLOPT_SSLVERSION.html)
+with `CURL_SSLVERSION_TLSv1_3`.
+
+Both the TLS 1.3 and TLS 1.2 cipher options expect a list of cipher suites
+separated by colons (`:`). This list is parsed opportunistically, cipher suites
+that are not recognized or implemented are ignored. As long as there is at
+least one recognized cipher suite in the list, the list is considered valid.
+
+For both the TLS 1.3 and TLS 1.2 cipher options, the order in which the
+cipher suites are specified determine the preference of them. When negotiating
+a TLS connection the server picks a cipher suite from the intersection of the
+cipher suites supported by the server and the cipher suites sent by curl. If
+the server is configured to honor the client's cipher preference, the first
+common cipher suite in the list sent by curl is chosen.
+
+### TLS 1.3 cipher suites
+
+Setting TLS 1.3 cipher suites is supported by curl with
+OpenSSL (1.1.1+, curl 7.61.0+), LibreSSL (3.4.1+, curl 8.3.0+),
+wolfSSL (curl 8.10.0+) and mbedTLS (3.6.0+, curl 8.10.0+).
+
+The list of cipher suites that can be used for the `--tls13-ciphers` option:
+```
+TLS_AES_128_GCM_SHA256
+TLS_AES_256_GCM_SHA384
+TLS_CHACHA20_POLY1305_SHA256
+TLS_AES_128_CCM_SHA256
+TLS_AES_128_CCM_8_SHA256
+```
+
+#### wolfSSL notes
+
+In addition to above list the following cipher suites can be used:
+`TLS_SM4_GCM_SM3` `TLS_SM4_CCM_SM3` `TLS_SHA256_SHA256` `TLS_SHA384_SHA384`.
+Usage of these cipher suites is not recommended. (The last two cipher suites
+are NULL ciphers, offering no encryption whatsoever.)
+
+### TLS 1.2 (1.1, 1.0) cipher suites
+
+Setting TLS 1.2 cipher suites is supported by curl with OpenSSL, LibreSSL,
+BoringSSL, mbedTLS (curl 8.8.0+), wolfSSL (curl 7.53.0+). Schannel does not
+support setting cipher suites directly, but does support setting algorithms
+(curl 7.61.0+), see Schannel notes below.
+
+For TLS 1.2 cipher suites there are multiple naming schemes, the two most used
+are with OpenSSL names (e.g. `ECDHE-RSA-AES128-GCM-SHA256`) and IANA names
+(e.g. `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256`). IANA names of TLS 1.2 cipher
+suites look similar to TLS 1.3 cipher suite names, to distinguish them note
+that TLS 1.2 names contain `_WITH_`, while TLS 1.3 names do not. When setting
+TLS 1.2 cipher suites with curl it is recommended that you use OpenSSL names
+as these are most widely recognized by the supported SSL backends.
+
+The complete list of cipher suites that may be considered for the `--ciphers`
+option is extensive, it consists of more than 300 ciphers suites. However,
+nowadays for most of them their usage is discouraged, and support for a lot of
+them have been removed from the various SSL backends, if ever implemented at
+all.
+
+A shortened list (based on [recommendations by
+Mozilla](https://wiki.mozilla.org/Security/Server_Side_TLS)) of cipher suites,
+which are (mostly) supported by all SSL backends, that can be used for the
+`--ciphers` option:
+```
+ECDHE-ECDSA-AES128-GCM-SHA256
+ECDHE-RSA-AES128-GCM-SHA256
+ECDHE-ECDSA-AES256-GCM-SHA384
+ECDHE-RSA-AES256-GCM-SHA384
+ECDHE-ECDSA-CHACHA20-POLY1305
+ECDHE-RSA-CHACHA20-POLY1305
+DHE-RSA-AES128-GCM-SHA256
+DHE-RSA-AES256-GCM-SHA384
+DHE-RSA-CHACHA20-POLY1305
+ECDHE-ECDSA-AES128-SHA256
+ECDHE-RSA-AES128-SHA256
+ECDHE-ECDSA-AES128-SHA
+ECDHE-RSA-AES128-SHA
+ECDHE-ECDSA-AES256-SHA384
+ECDHE-RSA-AES256-SHA384
+ECDHE-ECDSA-AES256-SHA
+ECDHE-RSA-AES256-SHA
+DHE-RSA-AES128-SHA256
+DHE-RSA-AES256-SHA256
+AES128-GCM-SHA256
+AES256-GCM-SHA384
+AES128-SHA256
+AES256-SHA256
+AES128-SHA
+AES256-SHA
+DES-CBC3-SHA
+```
+
+See this [list](https://github.com/curl/curl/blob/master/docs/CIPHERS-TLS12.md)
+for a complete list of TLS 1.2 cipher suites.
+
+#### OpenSSL notes
+
+In addition to specifying a list of cipher suites, OpenSSL also accepts a
+format with specific cipher strings (like `TLSv1.2`, `AESGCM`, `CHACHA20`) and
+`!`, `-` and `+` operators. Refer to the
+[OpenSSL cipher documentation](https://docs.openssl.org/master/man1/openssl-ciphers/#cipher-list-format)
+for further information on that format.
+
+#### Schannel notes
+
+Schannel does not support setting individual TLS 1.2 cipher suites directly.
+It only allows the enabling and disabling of encryption algorithms. These are
+in the form of `CALG_xxx`, see the [Schannel `ALG_ID`
+documentation](https://learn.microsoft.com/windows/win32/seccrypto/alg-id)
+for a list of these algorithms. Also, (since curl 7.77.0)
+`SCH_USE_STRONG_CRYPTO` can be given to pass that flag to Schannel, lookup the
+[documentation for the Windows version in
+use](https://learn.microsoft.com/windows/win32/secauthn/cipher-suites-in-schannel)
+to see how that affects the cipher suite selection. When not specifying the
+`--ciphers` and `--tls13-ciphers` options curl passes this flag by default.
+
+### Examples
+
+```sh
+curl \
+  --tls13-ciphers TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256 \
+  --ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:\
+ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305 \
+  https://example.com/
+```
+Restrict ciphers to `aes128-gcm` and `chacha20`. Works with OpenSSL, LibreSSL,
+mbedTLS and wolfSSL.
+
+```sh
+curl \
+  --tlsv1.3 \
+  --tls13-ciphers TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256 \
+  https://example.com/
+```
+Restrict to only TLS 1.3 with `aes128-gcm` and `chacha20` ciphers. Works with
+OpenSSL, LibreSSL, mbedTLS, wolfSSL and Schannel.
+
+```sh
+curl \
+  --ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:\
+ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305 \
+  https://example.com/
+```
+Restrict TLS 1.2 ciphers to `aes128-gcm` and `chacha20`, use default TLS 1.3
+ciphers (if TLS 1.3 is available). Works with OpenSSL, LibreSSL, BoringSSL,
+mbedTLS and wolfSSL.
+
+## ciphers, the GnuTLS way
+
+With GnuTLS, curl allows configuration of all TLS parameters via option
+[`--ciphers`](https://curl.se/docs/manpage.html#--ciphers)
+or
+[`CURLOPT_SSL_CIPHER_LIST`](https://curl.se/libcurl/c/CURLOPT_SSL_CIPHER_LIST.html)
+only. The option
+[`--tls13-ciphers`](https://curl.se/docs/manpage.html#--tls13-ciphers)
+or
+[`CURLOPT_TLS13_CIPHERS`](https://curl.se/libcurl/c/CURLOPT_TLS13_CIPHERS.html)
+is being ignored.
+
+`--ciphers` is used to set the GnuTLS **priority string** in
+the following way:
+
+* When the set string starts with '+', '-' or '!' it is *appended* to the
+  priority string libcurl itself generates (separated by ':'). This initial
+  priority depends other settings such as CURLOPT_SSLVERSION(3),
+  CURLOPT_TLSAUTH_USERNAME(3) (for SRP) or if HTTP/3 (QUIC)
+  is being negotiated.
+* Otherwise, the set string fully *replaces* the libcurl generated one. While
+  giving full control to the application, the set priority needs to
+  provide for everything the transfer may need to negotiate. Example: if
+  the set priority only allows TLSv1.2, all HTTP/3 attempts fail.
+
+Users may specify via `--ciphers` anything that GnuTLS supports: ciphers,
+key exchange, MAC, compression, TLS versions, signature algorithms, groups,
+elliptic curves, certificate types. In addition, GnuTLS has a variety of
+other keywords that tweak its operations. Applications or a system
+may define new alias names for priority strings that can then be used here.
+
+Since the order of items in priority strings is significant, it makes no
+sense for curl to puzzle other ssl options somehow together. `--ciphers`
+is the single way to change priority.
+
+### Examples
+
+```sh
+curl \
+  --ciphers '-CIPHER_ALL:+AES-128-GCM:+CHACHA20-POLY1305' \
+  https://example.com/
+```
+Restrict ciphers to `aes128-gcm` and `chacha20` in GnuTLS.
+
+```sh
+curl \
+  --ciphers 'NORMAL:-VERS-ALL:+TLS1.3:-AES-256-GCM' \
+  https://example.com/
+```
+Restrict to only TLS 1.3 without the `aes256-gcm` cipher.
+
+```sh
+curl \
+  --ciphers 'NORMAL:-VERS-ALL:+TLS1.2:-CIPHER_ALL:+CAMELLIA-128-GCM' \
+  https://example.com/
+```
+Restrict to only TLS 1.2 with the `CAMELLIA-128-GCM` cipher.

+
+# How to do code reviews for curl
+
+Anyone and everyone is encouraged and welcome to review code submissions in
+curl. This is a guide on what to check for and how to perform a successful
+code review.
+
+## All submissions should get reviewed
+
+All pull requests and patches submitted to the project should be reviewed by
+at least one experienced curl maintainer before that code is accepted and
+merged.
+
+## Let the tools and tests take the first rounds
+
+On initial pull requests, let the tools and tests do their job first and then
+start out by helping the submitter understand the test failures and tool
+alerts.
+
+## How to provide feedback to author
+
+Be nice. Ask questions. Provide examples or suggestions of improvements.
+Assume the best intentions. Remember language barriers.
+
+All first-time contributors can become regulars. Let's help them go there.
+
+## Is this a change we want?
+
+If this is not a change that seems to be aligned with the project's path
+forward and as such cannot be accepted, inform the author about this sooner
+rather than later. Do it gently and explain why and possibly what could be
+done to make it more acceptable.
+
+## API/ABI stability or changed behavior
+
+Changing the API and the ABI may be fine in a change but it needs to be done
+deliberately and carefully. If not, a reviewer must help the author to realize
+the mistake.
+
+curl and libcurl are similarly strict on not modifying existing behavior. API
+and ABI stability is not enough, the behavior should also remain intact as far
+as possible.
+
+## Code style
+
+Most code style nits are detected by checksrc but not all. Only leave remarks
+on style deviation once checksrc does not find anymore.
+
+Minor nits from fresh submitters can also be handled by the maintainer when
+merging, in case it seems like the submitter is not clear on what to do. We
+want to make the process fun and exciting for new contributors.
+
+## Encourage consistency
+
+Make sure new code is written in a similar style as existing code. Naming,
+logic, conditions, etc.
+
+## Are pointers always non-NULL?
+
+If a function or code rely on pointers being non-NULL, take an extra look if
+that seems to be a fair assessment.
+
+## Asserts
+
+Conditions that should never be false can be verified with `DEBUGASSERT()`
+calls to get caught in tests and debugging easier, while not having an impact
+on final or release builds.
+
+## Memory allocation
+
+Can the mallocs be avoided? Do not introduce mallocs in any hot paths. If
+there are (new) mallocs, can they be combined into fewer calls?
+
+Are all allocations handled in error paths to avoid leaks and crashes?
+
+## Thread-safety
+
+We do not like static variables as they break thread-safety and prevent
+functions from being reentrant.
+
+## Should features be `#ifdef`ed?
+
+Features and functionality may not be present everywhere and should therefore
+be `#ifdef`ed. Additionally, some features should be possible to switch on/off
+in the build.
+
+Write `#ifdef`s to be as little of a "maze" as possible.
+
+## Does it look portable enough?
+
+curl runs "everywhere". Does the code take a reasonable stance and enough
+precautions to be possible to build and run on most platforms?
+
+Remember that we live by C89 restrictions.
+
+## Tests and testability
+
+New features should be added in conjunction with one or more test cases.
+Ideally, functions should also be written so that unit tests can be done to
+test individual functions.
+
+## Documentation
+
+New features or changes to existing functionality **must** be accompanied by
+updated documentation. Submitting that in a separate follow-up pull request is
+not OK. A code review must also verify that the submitted documentation update
+matches the code submission.
+
+English is not everyone's first language, be mindful of this and help the
+submitter improve the text if it needs a rewrite to read better.
+
+## Code should not be hard to understand
+
+Source code should be written to maximize readability and be easy to
+understand.
+
+## Functions should not be large
+
+A single function should never be large as that makes it hard to follow and
+understand all the exit points and state changes. Some existing functions in
+curl certainly violate this ground rule but when reviewing new code we should
+propose splitting into smaller functions.
+
+## Duplication is evil
+
+Anything that looks like duplicated code is a red flag. Anything that seems to
+introduce code that we *should* already have or provide needs a closer check.
+
+## Sensitive data
+
+When credentials are involved, take an extra look at what happens with this
+data. Where it comes from and where it goes.
+
+## Variable types differ
+
+`size_t` is not a fixed size. `time_t` can be signed or unsigned and have
+different sizes. Relying on variable sizes is a red flag.
+
+Also remember that endianness and >= 32-bit accesses to unaligned addresses
+are problematic areas.
+
+## Integer overflows
+
+Be careful about integer overflows. Some variable types can be either 32-bit
+or 64-bit. Integer overflows must be detected and acted on *before* they
+happen.
+
+## Dangerous use of functions
+
+Maybe use of `realloc()` should rather use the dynbuf functions?
+
+Do not allow new code that grows buffers without using dynbuf.
+
+Use of C functions that rely on a terminating zero must only be used on data
+that really do have a null-terminating zero.
+
+## Dangerous "data styles"
+
+Make extra precautions and verify that memory buffers that need a terminating
+zero always have exactly that. Buffers *without* a null-terminator must not be
+used as input to string functions.
+
+# Commit messages
+
+Tightly coupled with a code review is making sure that the commit message is
+good. It is the responsibility of the person who merges the code to make sure
+that the commit message follows our standard (detailed in the
+[CONTRIBUTE](https://curl.se/dev/contribute.html) document). This includes
+making sure the PR identifies related issues and giving credit to reporters
+and helpers.

+
+# Contributing to the curl project
+
+This document is intended to offer guidelines on how to best contribute to the
+curl project. This concerns new features as well as corrections to existing
+flaws or bugs.
+
+## Join the Community
+
+Skip over to [https://curl.se/mail/](https://curl.se/mail/) and join
+the appropriate mailing list(s). Read up on details before you post
+questions. Read this file before you start sending patches. We prefer
+questions sent to and discussions being held on the mailing list(s), not sent
+to individuals.
+
+Before posting to one of the curl mailing lists, please read up on the
+[mailing list etiquette](https://curl.se/mail/etiquette.html).
+
+We also hang out on IRC in #curl on libera.chat
+
+If you are at all interested in the code side of things, consider clicking
+'watch' on the [curl repository on GitHub](https://github.com/curl/curl) to be
+notified of pull requests and new issues posted there.
+
+## License and copyright
+
+When contributing with code, you agree to put your changes and new code under
+the same license curl and libcurl is already using unless stated and agreed
+otherwise.
+
+If you add a larger piece of code, you can opt to make that file or set of
+files to use a different license as long as they do not enforce any changes to
+the rest of the package and they make sense. Such "separate parts" can not be
+GPL licensed (as we do not want copyleft to affect users of libcurl) but they
+must use "GPL compatible" licenses (as we want to allow users to use libcurl
+properly in GPL licensed environments).
+
+When changing existing source code, you do not alter the copyright of the
+original file(s). The copyright is still owned by the original creator(s) or
+those who have been assigned copyright by the original author(s).
+
+By submitting a patch to the curl project, you are assumed to have the right
+to the code and to be allowed by your employer or whatever to hand over that
+patch/code to us. We credit you for your changes as far as possible, to give
+credit but also to keep a trace back to who made what changes. Please always
+provide us with your full real name when contributing,
+
+## What To Read
+
+Source code, the man pages, the [INTERNALS
+document](https://curl.se/dev/internals.html),
+[TODO](https://curl.se/docs/todo.html),
+[KNOWN_BUGS](https://curl.se/docs/knownbugs.html) and the [most recent
+changes](https://curl.se/dev/sourceactivity.html) in git. Just lurking on the
+[curl-library mailing list](https://curl.se/mail/list.cgi?list=curl-library)
+gives you a lot of insights on what's going on right now. Asking there is a
+good idea too.
+
+## Write a good patch
+
+### Follow code style
+
+When writing C code, follow the
+[CODE_STYLE](https://curl.se/dev/code-style.html) already established in
+the project. Consistent style makes code easier to read and mistakes less
+likely to happen. Run `make checksrc` before you submit anything, to make sure
+you follow the basic style. That script does not verify everything, but if it
+complains you know you have work to do.
+
+### Non-clobbering All Over
+
+When you write new functionality or fix bugs, it is important that you do not
+fiddle all over the source files and functions. Remember that it is likely
+that other people have done changes in the same source files as you have and
+possibly even in the same functions. If you bring completely new
+functionality, try writing it in a new source file. If you fix bugs, try to
+fix one bug at a time and send them as separate patches.
+
+### Write Separate Changes
+
+It is annoying when you get a huge patch from someone that is said to fix 11
+odd problems, but discussions and opinions do not agree with 10 of them - or 9
+of them were already fixed in a different way. Then the person merging this
+change needs to extract the single interesting patch from somewhere within the
+huge pile of source, and that creates a lot of extra work.
+
+Preferably, each fix that corrects a problem should be in its own patch/commit
+with its own description/commit message stating exactly what they correct so
+that all changes can be selectively applied by the maintainer or other
+interested parties.
+
+Also, separate changes enable bisecting much better for tracking problems
+and regression in the future.
+
+### Patch Against Recent Sources
+
+Please try to get the latest available sources to make your patches against.
+It makes the lives of the developers so much easier. The best is if you get
+the most up-to-date sources from the git repository, but the latest release
+archive is quite OK as well.
+
+### Documentation
+
+Writing docs is dead boring and one of the big problems with many open source
+projects but someone's gotta do it. It makes things a lot easier if you submit
+a small description of your fix or your new features with every contribution
+so that it can be swiftly added to the package documentation.
+
+Documentation is mostly provided as manpages or plain ASCII files. The
+manpages are rendered from their source files that are usually written using
+markdown. Most HTML files on the website and in the release archives are
+generated from corresponding markdown and ASCII files.
+
+### Test Cases
+
+Since the introduction of the test suite, we can quickly verify that the main
+features are working as they are supposed to. To maintain this situation and
+improve it, all new features and functions that are added need to be tested in
+the test suite. Every feature that is added should get at least one valid test
+case that verifies that it works as documented. If every submitter also posts
+a few test cases, it does not end up a heavy burden on a single person.
+
+If you do not have test cases or perhaps you have done something that is hard
+to write tests for, do explain exactly how you have otherwise tested and
+verified your changes.
+
+# Submit Your Changes
+
+## Get your changes merged
+
+Ideally you file a [pull request on
+GitHub](https://github.com/curl/curl/pulls), but you can also send your plain
+patch to [the curl-library mailing
+list](https://curl.se/mail/list.cgi?list=curl-library).
+
+If you opt to post a patch on the mailing list, chances are someone converts
+it into a pull request for you, to have the CI jobs verify it proper before it
+can be merged. Be prepared that some feedback on the proposed change might
+then come on GitHub.
+
+Your changes be reviewed and discussed and you are expected to correct flaws
+pointed out and update accordingly, or the change risks stalling and
+eventually just getting deleted without action. As a submitter of a change,
+you are the owner of that change until it has been merged.
+
+Respond on the list or on GitHub about the change and answer questions and/or
+fix nits/flaws. This is important. We take lack of replies as a sign that you
+are not anxious to get your patch accepted and we tend to simply drop such
+changes.
+
+## About pull requests
+
+With GitHub it is easy to send a [pull
+request](https://github.com/curl/curl/pulls) to the curl project to have
+changes merged.
+
+We strongly prefer pull requests to mailed patches, as it makes it a proper
+git commit that is easy to merge and they are easy to track and not that easy
+to lose in the flood of many emails, like they sometimes do on the mailing
+lists.
+
+Every pull request submitted is automatically tested in several different
+ways. [See the CI document for more
+information](https://github.com/curl/curl/blob/master/docs/tests/CI.md).
+
+Sometimes the tests fail due to a dependency service temporarily being offline
+or otherwise unavailable, e.g. package downloads. In this case you can just
+try to update your pull requests to rerun the tests later as described below.
+
+You can update your pull requests by pushing new commits or force-pushing
+changes to existing commits. Force-pushing an amended commit without any
+actual content changed also allows you to retrigger the tests for that commit.
+
+When you adjust your pull requests after review, consider squashing the
+commits so that we can review the full updated version more easily.
+
+A pull request sent to the project might get labeled `needs-votes` by a
+project maintainer. This label means that in addition to meeting all other
+checks and qualifications this pull request must also receive more "votes" of
+user support. More signs that people want this to happen. It could be in the
+form of messages saying so, or thumbs-up reactions on GitHub.
+
+## When the pull request is approved
+
+If it does not seem to get approved when you think it is ready - feel free to
+ask for approval.
+
+Once your pull request has been approved it can be merged by a maintainer.
+
+For new features, or changes, we require that the *feature window* is open for
+the pull request to be merged. This is typically a three week period that
+starts ten days after a previous release. New features submitted as pull
+requests while the window is closed simply have to wait until it opens to get
+merged.
+
+If time passes without your approved pull request gets merged: feel free to
+ask what more you can do to make it happen.
+
+## Making quality changes
+
+Make the patch against as recent source versions as possible.
+
+If you have followed the tips in this document and your patch still has not
+been incorporated or responded to after some weeks, consider resubmitting it
+to the list or better yet: change it to a pull request.
+
+## Commit messages
+
+How to write git commit messages in the curl project.
+
+    ---- start ----
+    [area]: [short line describing the main effect]
+           -- empty line --
+    [full description, no wider than 72 columns that describes as much as
+    possible as to why this change is made, and possibly what things
+    it fixes and everything else that is related,
+    -- end --
+
+The first line is a succinct description of the change and should ideally work
+as a single line in the RELEASE NOTES.
+
+ - use the imperative, present tense: **change** not "changed" nor "changes"
+ - do not capitalize the first letter
+ - no period (.) at the end
+
+The `[area]` in the first line can be `http2`, `cookies`, `openssl` or
+similar. There is no fixed list to select from but using the same "area" as
+other related changes could make sense.
+
+## Commit message keywords
+
+Use the following ways to improve the message and provide pointers to related
+work.
+
+- `Follow-up to {shorthash}` - if this fixes or continues a previous commit;
+add a `Ref:` that commit's PR or issue if it is not a small, obvious fix;
+followed by an empty line
+
+- `Bug: URL` to the source of the report or more related discussion; use
+`Fixes` for GitHub issues instead when that is appropriate.
+
+- `Approved-by: John Doe` - credit someone who approved the PR.
+
+- `Authored-by: John Doe` - credit the original author of the code; only use
+this if you cannot use `git commit --author=...`.
+
+- `Signed-off-by: John Doe` - we do not use this, but do not bother removing
+  it.
+
+- `whatever-else-by:` credit all helpers, finders, doers; try to use one of
+the following keywords if at all possible, for consistency: `Acked-by:`,
+`Assisted-by:`, `Co-authored-by:`, `Found-by:`, `Reported-by:`,
+`Reviewed-by:`, `Suggested-by:`, `Tested-by:`.
+
+- `Ref: #1234` - if this is related to a GitHub issue or PR, possibly one that
+has already been closed.
+
+- `Ref: URL` to more information about the commit; use `Bug:` instead for a
+reference to a bug on another bug tracker]
+
+- `Fixes #1234` - if this fixes a GitHub issue; GitHub closes the issue once
+this commit is merged.
+
+- `Closes #1234` - if this merges a GitHub PR; GitHub closes the PR once this
+commit is merged.
+
+Do not forget to use commit with `--author` if you commit someone else's work,
+and make sure that you have your own user and email setup correctly in git
+before you commit.
+
+Add whichever header lines as appropriate, with one line per person if more
+than one person was involved. There is no need to credit yourself unless you
+are using `--author` which hides your identity. Do not include people's email
+addresses in headers to avoid spam, unless they are already public from a
+previous commit; saying `{userid} on github` is OK.
+
+## Push Access
+
+If you are a frequent contributor, you may be given push access to the git
+repository and then you are able to push your changes straight into the git
+repository instead of sending changes as pull requests or by mail as patches.
+
+Just ask if this is what you would want. You are required to have posted
+several high quality patches first, before you can be granted push access.
+
+## Useful resources
+ - [Webinar on getting code into cURL](https://www.youtube.com/watch?v=QmZ3W1d6LQI)
+
+# Update copyright and license information
+
+There is a CI job called **REUSE compliance / check** that runs on every pull
+request and commit to verify that the *REUSE state* of all files are still
+fine.
+
+This means that all files need to have their license and copyright information
+clearly stated. Ideally by having the standard curl source code header, with
+the `SPDX-License-Identifier` included. If the header does not work, you can
+use a smaller header or add the information for a specific file to the
+`REUSE.toml` file.
+
+You can manually verify the copyright and compliance status by running the
+[REUSE helper tool](https://github.com/fsfe/reuse-tool): `reuse lint`
+
+# On AI use in curl
+
+Guidelines for AI use when contributing to curl.
+
+## For security reports and other issues
+
+If you asked an AI tool to find problems in curl, you **must** make sure to
+reveal this fact in your report.
+
+You must also double-check the findings carefully before reporting them to us
+to validate that the issues are indeed existing and working exactly as the AI
+says. AI-based tools frequently generate inaccurate or fabricated results.
+
+Further: it is *rarely* a good idea to just copy and paste an AI generated
+report to the project. Those generated reports typically are too wordy and
+rarely to the point (in addition to the common fabricated details). If you
+actually find a problem with an AI and you have verified it yourself to be
+true: write the report yourself and explain the problem as you have learned
+it. This makes sure the AI-generated inaccuracies and invented issues are
+filtered out early before they waste more people's time.
+
+As we take security reports seriously, we investigate each report with
+priority. This work is both time and energy consuming and pulls us away from
+doing other meaningful work. Fake and otherwise made up security problems
+effectively prevent us from doing real project work and make us waste time and
+resources.
+
+We ban users immediately who submit made up fake reports to the project.
+
+## For pull requests
+
+When contributing content to the curl project, you give us permission to use
+it as-is and you must make sure you are allowed to distribute it to us. By
+submitting a change to us, you agree that the changes can and should be
+adopted by curl and get redistributed under the curl license. Authors should
+be explicitly aware that the burden is on them to ensure no unlicensed code is
+submitted to the project.
+
+This is independent if AI is used or not.
+
+When contributing a pull request you should of course always make sure that
+the proposal is good quality and a best effort that follows our guidelines. A
+basic rule of thumb is that if someone can spot that the contribution was made
+with the help of AI, you have more work to do.
+
+We can accept code written with the help of AI into the project, but the code
+must still follow coding standards, be written clearly, be documented, feature
+test cases and adhere to all the normal requirements we have.
+
+## For translation
+
+Translation services help users write reports, texts and documentation in
+non-native languages and we encourage and welcome such contributors and
+contributions.
+
+As AI-based translation tools sometimes have a way to make the output sound a
+little robotic and add an "AI tone" to the text, you may want to consider
+mentioning that you used such a tool. Failing to do so risks that maintainers
+wrongly dismiss translated texts as AI slop.

+# curldown
+
+A markdown-like syntax for libcurl man pages.
+
+## Purpose
+
+A text format for writing libcurl documentation in the shape of man pages.
+
+Make it easier for users to contribute and write documentation. A format that
+is easier on the eye in its source format.
+
+Make it harder to do syntactical mistakes.
+
+Use a format that allows creating man pages that end up looking exactly like
+the man pages did when we wrote them in nroff format.
+
+Take advantage of the fact that people these days are accustomed to markdown
+by using a markdown-like syntax.
+
+This allows us to fix issues in the nroff format easier since now we generate
+them. For example: escaping minus to prevent them from being turned into
+Unicode by man.
+
+Generate nroff output that looks (next to) *identical* to the previous files,
+so that the look, existing test cases, HTML conversions, existing
+infrastructure etc remain mostly intact.
+
+Contains meta-data in a structured way to allow better output (for example the
+see also information) and general awareness of what the file is about.
+
+## File extension
+
+Since curldown looks similar to markdown, we use `.md` extensions on the
+files.
+
+## Conversion
+
+Convert **from curldown to nroff** with `cd2nroff`. Generates nroff man pages.
+
+Convert **from nroff to curldown** with `nroff2cd`. This is only meant to be
+used for the initial conversion to curldown and should ideally never be needed
+again.
+
+Convert, check or clean up an existing curldown to nicer, better, cleaner
+curldown with **cd2cd**.
+
+Mass-convert all curldown files to nroff in specified directories with
+`cdall`:
+
+    cdall [dir1] [dir2] [dir3] ..
+
+## Known issues
+
+The `cd2nroff` tool does not yet handle *italics* or **bold** where the start
+and the end markers are used on separate lines.
+
+The `nroff2cd` tool generates code style quotes for all `.fi` sections since
+the nroff format does not carry a distinction.
+
+# Format
+
+Each curldown starts with a header with meta-data:
+
+    ---
+    c: Copyright (C) Daniel Stenberg, <daniel@haxx.se>, et al.
+    SPDX-License-Identifier: curl
+    Title: CURLOPT_AWS_SIGV4
+    Section: 3
+    Source: libcurl
+    Protocol:
+      - HTTP
+    See-also:
+      - CURLOPT_HEADEROPT (3)
+      - CURLOPT_HTTPAUTH (3)
+    TLS-backend:
+      - [name]
+    Added-in: [version or "n/a"]
+    ---
+
+All curldown files *must* have all the headers present and at least one
+`See-also:` entry specified.
+
+If the man page is for section 3 (library related). The `Protocol` list must
+contain at least one protocol, which can be `*` if the option is virtually for
+everything. If `*` is used, it must be the only listed protocol. Recognized
+protocols are either URL schemes (in uppercase), `TLS` or `TCP`.
+
+If the `Protocol` list contains `TLS`, then there must also be a `TLS-backend`
+list, specifying `All` or a list of what TLS backends that work with this
+option. The available TLS backends are:
+
+- `GnuTLS`
+- `mbedTLS`
+- `OpenSSL` (also covers BoringSSL, LibreSSL, quictls, AWS-LC and AmiSSL)
+- `rustls`
+- `Schannel`
+- `wolfSSL`
+- `All`: all TLS backends
+
+Following the header in the file, is the manual page using markdown-like
+syntax:
+
+~~~
+    # NAME
+    a page - this is a page describing something
+
+    # SYNOPSIS
+    ~~~c
+    #include <curl/curl.h>
+
+    CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AWS_SIGV4, char *param);
+    ~~~
+~~~
+
+Quoted source code should start with `~~~c` and end with `~~~` while regular
+quotes can start with `~~~` or just be indented with 4 spaces.
+
+Headers at top-level `#` get converted to `.SH`.
+
+`nroff2cd` supports the `##` next level header which gets converted to `.IP`.
+
+Write bold words or phrases within `**` like:
+
+    This is a **bold** word.
+
+Write italics like:
+
+    This is *italics*.
+
+Due to how man pages do not support backticks especially formatted, such
+occurrences in the source are instead just using italics in the generated
+output:
+
+    This `word` appears in italics.
+
+When generating the nroff output, the tooling removes superfluous newlines,
+meaning they can be used freely in the source file to make the text more
+readable.
+
+To make sure curldown documents render correctly as markdown, all literal
+occurrences of `<` or `>` need to be escaped by a leading backslash.
+
+## Generating contents
+
+`# %PROTOCOLS%` - inserts a **PROTOCOLS** section based on the metadata
+provided in the header.
+
+`# %AVAILABILITY%` - inserts an **AVAILABILITY** section based on the metadata
+provided in the header.
+
+## Symbols
+
+All mentioned curl symbols that have their own man pages, like
+`curl_easy_perform(3)` are automatically rendered using italics in the output
+without having to enclose it with asterisks. This helps ensuring that they get
+converted to links properly later in the HTML version on the website, as
+converted with `roffit`. This makes the curldown text easier to read even when
+mentioning many curl symbols.
+
+This auto-linking works for patterns matching `(lib|)curl[^ ]*(3)`.

+If any of these deprecated features is a cause for concern for you, please
+email the
+[curl-library mailing list](https://lists.haxx.se/listinfo/curl-library)
+as soon as possible and explain to us why this is a problem for you and
+how your use case cannot be satisfied properly using a workaround.
+
+## Windows CE
+
+Windows CE "mainstream support" ended on October 9, 2018, and "Extended
+Support" ended on October 10, 2023.
+
+curl drops all support in November 2025.
+
+## VS2008
+
+curl drops support for getting built with Microsoft Visual Studio 2008 in
+November 2025.
+
+The only reason we kept support for this version is for Windows CE - and we
+intend to remove support for that Operating System in this time frame as well.
+Bumping the minimum to VS2010. VS2008 is a pain to support.
+
+Previous discussion and details: https://github.com/curl/curl/discussions/15972
+
+## Windows XP
+
+In January 2026, curl drops support for Windows XP and Server 2003. Their
+"mainstream support" ended in 2014, with final updates on May 14, 2019.
+
+Making the new minimum target Windows version Vista / Server 2008.
+
+## c-ares 1.16.0
+
+In March 2026, we drop support for all c-ares versions before 1.16.0.
+
+## OpenSSL 1.0.2
+
+OpenSSL and others only ship fixes for this version to paying customers,
+meaning users of the free version risk being vulnerable.
+
+We remove support for this OpenSSL version from curl in December 2025.
+
+## OpenSSL 1.1.1
+
+OpenSSL and others only ship fixes to paying customers, meaning users of the
+free version risk being vulnerable.
+
+We remove support for this OpenSSL version from curl in December 2025.
+
+## OpenSSL-QUIC
+
+OpenSSL-QUIC is what we call the curl QUIC backend that uses the OpenSSL QUIC
+stack.
+
+ - It is slower and uses more memory than the alternatives and is only
+   experimental in curl.
+ - It gets little attention from OpenSSL and we have no expectation of the
+   major flaws getting corrected anytime soon.
+ - No one has spoken up for keeping it
+ - curl users building with vanilla OpenSSL can still use QUIC through the
+   means of ngtcp2
+
+We remove the OpenSSL-QUIC backend in March 2026.
+
+## Past removals
+
+ - axTLS (removed in 7.63.0)
+ - Pipelining (removed in 7.65.0)
+ - PolarSSL (removed in 7.69.0)
+ - NPN (removed in 7.86.0)
+ - Support for systems without 64-bit data types (removed in 8.0.0)
+ - NSS (removed in 8.3.0)
+ - gskit (removed in 8.3.0)
+ - MinGW v1 (removed in 8.4.0)
+ - NTLM_WB (removed in 8.8.0)
+ - space-separated `NOPROXY` patterns (removed in 8.9.0)
+ - hyper (removed in 8.12.0)
+ - Support for Visual Studio 2005 and older (removed in 8.13.0)
+ - Secure Transport (removed in 8.15.0)
+ - BearSSL (removed in 8.15.0)
+ - msh3 (removed in 8.16.0)
+ - winbuild build system (removed in 8.17.0)

+# How to determine if an early patch release is warranted
+
+In the curl project we do releases every 8 weeks. Unless we break the cycle
+and do an early patch release.
+
+We do frequent releases partly to always have the next release "not too far
+away".
+
+## Bugfix
+
+During the release cycle, and especially in the beginning of a new cycle (the
+so-called "cool down" period), there are times when a bug is reported and
+after it has been subsequently fixed correctly, the question might be asked:
+is this bug and associated fix important enough for an early patch release?
+
+The question can only be properly asked when a fix has been created and landed
+in the git master branch.
+
+## Early release
+
+An early patch release means that we ship a new, complete and full release
+called `major.minor.patch` where the `patch` part is increased by one since
+the previous release. A curl release is a curl release. There is no small or
+big and we never release just a patch. There is only "release".
+
+## Questions to ask
+
+ - Is there a security advisory rated high or critical?
+ - Is there a data corruption bug?
+ - Did the bug cause an API/ABI breakage?
+ - Does the problem annoy a significant share of the user population?
+
+If the answer is yes to one or more of the above, an early release might be
+warranted.
+
+More questions to ask ourselves when doing the assessment if the answers to
+the three ones above are all 'no'.
+
+ - Does the bug cause curl to prematurely terminate?
+ - How common is the affected buggy option/feature/protocol/platform to get
+   used?
+ - How large is the estimated impacted user base?
+ - Does the bug block something crucial for applications or other adoption of
+   curl "out there" ?
+ - Does the bug cause problems for curl developers or others on "the curl
+   team" ?
+ - Is the bug limited to the curl tool only? That might have a smaller impact
+   than a bug also present in libcurl.
+ - Is there a (decent) workaround?
+ - Is it a regression? Is the bug introduced in this release?
+ - Can the bug be fixed "easily" by applying a patch?
+ - Does the bug break the build? Most users do not build curl themselves.
+ - How long is it until the already scheduled next release?
+ - Can affected users safely rather revert to a former release until the next
+   scheduled release?
+ - Is it a performance regression with no functionality side-effects? If so it
+   has to be substantial.
+
+## If an early release is deemed necessary
+
+Unless done for security or similarly important reasons, an early release
+should not be done within a week of the previous release.
+
+This, to enable us to collect and bundle more fixes into the same release to
+make the release more worthwhile for everyone and to allow more time for fixes
+to settle and things to get tested. Getting a release in shape and done in
+style is work that should not be rushed.

+# Building curl with HTTPS-RR and ECH support
+
+We have added support for ECH to curl. It can use HTTPS RRs published in the
+DNS if curl uses DoH, or else can accept the relevant ECHConfigList values
+from the command line. This works with OpenSSL, wolfSSL, BoringSSL, AWS-LC
+or rustls-ffi as the TLS provider.
+
+This feature is EXPERIMENTAL. DO NOT USE IN PRODUCTION.
+
+This should however provide enough of a proof-of-concept to prompt an informed
+discussion about a good path forward for ECH support in curl.
+
+## OpenSSL Build
+
+To build the OpenSSL project's ECH feature branch:
+
+```sh
+cd $HOME/code
+git clone https://github.com/openssl/openssl --branch feature/ech
+cd openssl
+./config --libdir=lib --prefix=$HOME/code/openssl-local-inst
+...stuff...
+make -j8
+...more stuff...
+make install_sw
+...a little bit of stuff...
+```
+
+To build curl ECH-enabled, making use of the above:
+
+```sh
+cd $HOME/code
+git clone https://github.com/curl/curl
+cd curl
+autoreconf -fi
+LDFLAGS="-Wl,-rpath,$HOME/code/openssl-local-inst/lib/" ./configure --with-ssl=$HOME/code/openssl-local-inst --enable-ech
+...lots of output...
+WARNING: ECH HTTPSRR enabled but marked EXPERIMENTAL...
+make
+...lots more output...
+```
+
+If you do not get that WARNING at the end of the ``configure`` command, then
+ECH is not enabled, so go back some steps and re-do whatever needs re-doing:-)
+If you want to debug curl then you should add ``--enable-debug`` to the
+``configure`` command.
+
+In a recent (2024-05-20) build on one machine, configure failed to find the
+ECH-enabled SSL library, apparently due to the existence of
+``$HOME/code/openssl-local-inst/lib/pkgconfig`` as a directory containing
+various settings. Deleting that directory worked around the problem but may
+not be the best solution.
+
+## Using ECH and DoH
+
+curl supports using DoH for A/AAAA lookups so it was relatively easy to add
+retrieval of HTTPS RRs in that situation. To use ECH and DoH together:
+
+```sh
+cd $HOME/code/curl
+LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl --ech true --doh-url https://one.one.one.one/dns-query https://defo.ie/ech-check.php
+...
+SSL_ECH_STATUS: success <img src="greentick-small.png" alt="good" /> <br/>
+...
+```
+
+The output snippet above is within the HTML for the webpage, when things work.
+
+The above works for these test sites:
+
+```sh
+https://defo.ie/ech-check.php
+https://draft-13.esni.defo.ie:8413/stats
+https://draft-13.esni.defo.ie:8414/stats
+https://crypto.cloudflare.com/cdn-cgi/trace
+https://tls-ech.dev
+```
+
+The list above has 4 different server technologies, implemented by 3 different
+parties, and includes a case (the port 8414 server) where HelloRetryRequest
+(HRR) is forced.
+
+We currently support the following new curl command line arguments/options:
+
+- ``--ech <config>`` - the ``config`` value can be one of:
+    - ``false`` says to not attempt ECH
+    - ``true`` says to attempt ECH, if possible
+    - ``grease`` if attempting ECH is not possible, then send a GREASE ECH extension
+    - ``hard`` hard-fail the connection if ECH cannot be attempted
+    - ``ecl:<b64value>`` a base64 encoded ECHConfigList, rather than one accessed from the DNS
+    - ``pn:<name>`` override the ``public_name`` from an ECHConfigList
+
+Note that in the above "attempt ECH" means the client emitting a TLS
+ClientHello with a "real" ECH extension, but that does not mean that the
+relevant server can succeed in decrypting, as things can fail for other
+reasons.
+
+## Supplying an ECHConfigList on the command line
+
+To supply the ECHConfigList on the command line, you might need a bit of
+cut-and-paste, e.g.:
+
+```sh
+dig +short https defo.ie
+1 . ipv4hint=213.108.108.101 ech=AED+DQA8PAAgACD8WhlS7VwEt5bf3lekhHvXrQBGDrZh03n/LsNtAodbUAAEAAEAAQANY292ZXIuZGVmby5pZQAA ipv6hint=2a00:c6c0:0:116:5::10
+```
+
+Then paste the base64 encoded ECHConfigList onto the curl command line:
+
+```sh
+LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl --ech ecl:AED+DQA8PAAgACD8WhlS7VwEt5bf3lekhHvXrQBGDrZh03n/LsNtAodbUAAEAAEAAQANY292ZXIuZGVmby5pZQAA https://defo.ie/ech-check.php
+...
+SSL_ECH_STATUS: success <img src="greentick-small.png" alt="good" /> <br/>
+...
+```
+
+The output snippet above is within the HTML for the webpage.
+
+If you paste in the wrong ECHConfigList (it changes hourly for ``defo.ie``) you
+should get an error like this:
+
+```sh
+LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl -vvv --ech ecl:AED+DQA8yAAgACDRMQo+qYNsNRNj+vfuQfFIkrrUFmM4vogucxKj/4nzYgAEAAEAAQANY292ZXIuZGVmby5pZQAA https://defo.ie/ech-check.php
+...
+* OpenSSL/3.3.0: error:0A00054B:SSL routines::ech required
+...
+```
+
+There is a reason to want this command line option - for use before publishing
+an ECHConfigList in the DNS as per the Internet-draft [A well-known URI for
+publishing ECHConfigList values](https://datatracker.ietf.org/doc/draft-ietf-tls-wkech/).
+
+If you do use a wrong ECHConfigList value, then the server might return a
+good value, via the ``retry_configs`` mechanism. You can see that value in
+the verbose output, e.g.:
+
+```sh
+LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl -vvv --ech ecl:AED+DQA8yAAgACDRMQo+qYNsNRNj+vfuQfFIkrrUFmM4vogucxKj/4nzYgAEAAEAAQANY292ZXIuZGVmby5pZQAA https://defo.ie/ech-check.php
+...
+* ECH: retry_configs AQD+DQA8DAAgACBvYqJy+Hgk33wh/ZLBzKSPgwxeop7gvojQzfASq7zeZQAEAAEAAQANY292ZXIuZGVmby5pZQAA/g0APEMAIAAgXkT5r4cYs8z19q5rdittyIX8gfQ3ENW4wj1fVoiJZBoABAABAAEADWNvdmVyLmRlZm8uaWUAAP4NADw2ACAAINXSE9EdXzEQIJZA7vpwCIQsWqsFohZARXChgPsnfI1kAAQAAQABAA1jb3Zlci5kZWZvLmllAAD+DQA8cQAgACASeiD5F+UoSnVoHvA2l1EifUVMFtbVZ76xwDqmMPraHQAEAAEAAQANY292ZXIuZGVmby5pZQAA
+* ECH: retry_configs for defo.ie from cover.defo.ie, 319
+...
+```
+
+At that point, you could copy the base64 encoded value above and try again.
+For now, this only works for the OpenSSL and BoringSSL/AWS-LC builds.
+
+## Default settings
+
+curl has various ways to configure default settings, e.g. in ``$HOME/.curlrc``,
+so one can set the DoH URL and enable ECH that way:
+
+```sh
+cat ~/.curlrc
+doh-url=https://one.one.one.one/dns-query
+silent
+ech=true
+```
+
+Note that when you use the system's curl command (rather than our ECH-enabled
+build), it is liable to warn that ``ech`` is an unknown option. If that is an
+issue (e.g. if some script re-directs stdout and stderr somewhere) then adding
+the ``silent`` line above seems to be a good enough fix. (Though of
+course, yet another script could depend on non-silent behavior, so you may have
+to figure out what you prefer yourself.) That seems to have changed with the
+latest build, previously ``silent=TRUE`` was what I used in ``~/.curlrc`` but
+now that seems to cause a problem, so that the following line(s) are ignored.
+
+If you want to always use our OpenSSL build you can set ``LD_LIBRARY_PATH``
+in the environment:
+
+```sh
+export LD_LIBRARY_PATH=$HOME/code/openssl
+```
+
+When you do the above, there can be a mismatch between OpenSSL versions
+for applications that check that. A ``git push`` for example fails so you
+should unset ``LD_LIBRARY_PATH`` before doing that or use a different shell.
+
+```sh
+git push
+OpenSSL version mismatch. Built against 30000080, you have 30200000
+...
+```
+
+With all that setup as above the command line gets simpler:
+
+```sh
+./src/curl https://defo.ie/ech-check.php
+...
+SSL_ECH_STATUS: success <img src="greentick-small.png" alt="good" /> <br/>
+...
+```
+
+The ``--ech true`` option is opportunistic, so tries to do ECH but does not fail if
+the client for example cannot find any ECHConfig values. The ``--ech hard``
+option hard-fails if there is no ECHConfig found in DNS, so for now, that is not
+a good option to set as a default. Once ECH has really been attempted by
+the client, if decryption on the server side fails, then curl fails.
+
+## Code changes for ECH support when using DoH
+
+Code changes are ``#ifdef`` protected via ``USE_ECH`` or ``USE_HTTPSRR``:
+
+- ``USE_HTTPSRR`` is used for HTTPS RR retrieval code that could be generically
+  used should non-ECH uses for HTTPS RRs be identified, e.g. use of ALPN values
+  or IP address hints.
+
+- ``USE_ECH`` protects ECH specific code.
+
+There are various obvious code blocks for handling the new command line
+arguments which are not described here, but should be fairly clear.
+
+As shown in the ``configure`` usage above, there are ``configure.ac`` changes
+that allow separately dis/enabling ``USE_HTTPSRR`` and ``USE_ECH``. If ``USE_ECH``
+is enabled, then ``USE_HTTPSRR`` is forced. In both cases ``CURL_DISABLE_DOH``
+must not be enabled. (There may be some configuration conflicts available for the
+determined :-)
+
+The main functional change, as you would expect, is in ``lib/vtls/openssl.c``
+where an ECHConfig, if available from command line or DNS cache, is fed into
+the OpenSSL library via the new APIs implemented in our OpenSSL fork for that
+purpose. This code also implements the opportunistic (``--ech true``) or hard-fail
+(``--ech hard``) logic.
+
+Other than that, the main additions are in ``lib/doh.c``
+where we reuse ``dohprobe()`` to retrieve an HTTPS RR value for the target
+domain. If such a value is found, that is stored using a new ``doh_store_https()``
+function in a new field in the ``dohentry`` structure.
+
+The qname for the DoH query is modified if the port number is not 443, as
+defined in the SVCB specification.
+
+When the DoH process has worked, ``Curl_doh_is_resolved()`` now also returns
+the relevant HTTPS RR value data in the ``Curl_dns_entry`` structure.
+That is later accessed when the TLS session is being established, if ECH is
+enabled (from ``lib/vtls/openssl.c`` as described above).
+
+## Limitations
+
+Things that need fixing, but that can probably be ignored for the
+moment:
+
+- We could easily add code to make use of an ``alpn=`` value found in an HTTPS
+  RR, passing that on to OpenSSL for use as the "inner" ALPN value, but have
+yet to do that.
+
+Current limitations (more interesting than the above):
+
+- Only the first HTTPS RR value retrieved is actually processed as described
+  above, that could be extended in future, though picking the "right" HTTPS RR
+could be non-trivial if multiple RRs are published - matching IP address hints
+versus A/AAAA values might be a good basis for that. Last I checked though,
+browsers supporting ECH did not handle multiple HTTPS RRs well, though that
+needs re-checking as it has been a while.
+
+- It is unclear how one should handle any IP address hints found in an HTTPS RR.
+  It may be that a bit of consideration of how "multi-CDN" deployments might
+emerge would provide good answers there, but for now, it is not clear how best
+curl might handle those values when present in the DNS.
+
+- The SVCB/HTTPS RR specification supports a new "CNAME at apex" indirection
+  ("aliasMode") - the current code takes no account of that at all. One could
+envisage implementing the equivalent of following CNAMEs in such cases, but
+it is not clear if that'd be a good plan. (As of now, chrome browsers do not seem
+to have any support for that "aliasMode" and we have not checked Firefox for that
+recently.)
+
+- We have not investigated what related changes or additions might be needed
+  for applications using libcurl, as opposed to use of curl as a command line
+tool.
+
+- We have not yet implemented tests as part of the usual curl test harness as
+doing so would seem to require re-implementing an ECH-enabled server as part
+of the curl test harness. For now, we have a ``./tests/ech_test.sh`` script
+that attempts ECH with various test servers and with many combinations of the
+allowed command line options. While that is a useful test and has find issues,
+it is not comprehensive and we are not (as yet) sure what would be the right
+level of coverage. When running that script you should not have a
+``$HOME/.curlrc`` file that affects ECH or some of the negative tests could
+produce spurious failures.
+
+## Building with cmake
+
+To build with cmake, assuming our ECH-enabled OpenSSL is as before:
+
+```sh
+cd $HOME/code
+git clone https://github.com/curl/curl
+cd curl
+mkdir build
+cd build
+cmake -DOPENSSL_ROOT_DIR=$HOME/code/openssl -DUSE_ECH=1 ..
+...
+make
+...
+[100%] Built target curl
+```
+
+The binary produced by the cmake build does not need any ECH-specific
+``LD_LIBRARY_PATH`` setting.
+
+## BoringSSL build
+
+BoringSSL is also supported by curl and also supports ECH, so to build
+with that, instead of our ECH-enabled OpenSSL:
+
+```sh
+cd $HOME/code
+git clone https://boringssl.googlesource.com/boringssl
+cd boringssl
+cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME/code/boringssl/inst -DBUILD_SHARED_LIBS=1
+make
+...
+make install
+```
+
+Then:
+
+```sh
+cd $HOME/code
+git clone https://github.com/curl/curl
+cd curl
+autoreconf -fi
+LDFLAGS="-Wl,-rpath,$HOME/code/boringssl/inst/lib" ./configure --with-ssl=$HOME/code/boringssl/inst --enable-ech
+...lots of output...
+WARNING: ECH HTTPSRR enabled but marked EXPERIMENTAL. Use with caution.
+make
+```
+
+The BoringSSL/AWS-LC APIs are fairly similar to those in our ECH-enabled
+OpenSSL fork, so code changes are also in ``lib/vtls/openssl.c``, protected
+via ``#ifdef OPENSSL_IS_BORINGSSL`` and are mostly obvious API variations.
+
+The BoringSSL/AWS-LC APIs however do not support the ``--ech pn:`` command
+line variant as of now.
+
+## wolfSSL build
+
+wolfSSL also supports ECH and can be used by curl, so here's how:
+
+```sh
+cd $HOME/code
+git clone https://github.com/wolfSSL/wolfssl
+cd wolfssl
+./autogen.sh
+./configure --prefix=$HOME/code/wolfssl/inst --enable-ech --enable-debug --enable-opensslextra
+make
+make install
+```
+
+The install prefix (``inst``) in the above causes wolfSSL to be installed there
+and we seem to need that for the curl configure command to work out. The
+``--enable-opensslextra`` turns out (after much faffing about;-) to be
+important or else we get build problems with curl below.
+
+```sh
+cd $HOME/code
+git clone https://github.com/curl/curl
+cd curl
+autoreconf -fi
+./configure --with-wolfssl=$HOME/code/wolfssl/inst --enable-ech
+make
+```
+
+There are some known issues with the ECH implementation in wolfSSL:
+
+- The main issue is that the client currently handles HelloRetryRequest
+  incorrectly.  [HRR issue](https://github.com/wolfSSL/wolfssl/issues/6802).)
+  The HRR issue means that the client does not work for
+  [this ECH test web site](https://tls-ech.dev/) and any other similarly
+  configured sites.
+- There is also an issue related to so-called middlebox compatibility mode.
+  [middlebox compatibility issue](https://github.com/wolfSSL/wolfssl/issues/6774)
+
+### Code changes to support wolfSSL
+
+There are what seem like oddball differences:
+
+- The DoH URL in``$HOME/.curlrc`` can use `1.1.1.1` for OpenSSL but has to be
+  `one.one.one.one` for wolfSSL. The latter works for both, so OK, we us that.
+- There seems to be some difference in CA databases too - the wolfSSL version
+  does not like ``defo.ie``, whereas the system and OpenSSL ones do. We can
+  ignore that for our purposes via ``--insecure``/``-k`` but would need to fix
+  for a real setup. (Browsers do like those certificates though.)
+
+Then there are some functional code changes:
+
+- tweak to ``configure.ac`` to check if wolfSSL has ECH or not
+- added code to ``lib/vtls/wolfssl.c`` mirroring what's done in the
+  OpenSSL equivalent above.
+- wolfSSL does not support ``--ech false`` or the ``--ech pn:`` command line
+  argument.
+
+The lack of support for ``--ech false`` is because wolfSSL has decided to
+always at least GREASE if built to support ECH. In other words, GREASE is
+a compile time choice for wolfSSL, but a runtime choice for OpenSSL or
+BoringSSL/AWS-LC. (Both are reasonable.)
+
+## Additional notes
+
+### Supporting ECH without DoH
+
+All of the above only applies if DoH is being used. There should be a use-case
+for ECH when DoH is not used by curl - if a system stub resolver supports DoT
+or DoH, then, considering only ECH and the network threat model, it would make
+sense for curl to support ECH without curl itself using DoH. The author for
+example uses a combination of stubby+unbound as the system resolver listening
+on localhost:53, so would fit this use-case. That said, it is unclear if
+this is a niche that is worth trying to address. (The author is just as happy to
+let curl use DoH to talk to the same public recursive that stubby might use:-)
+
+Assuming for the moment this is a use-case we would like to support, then if
+DoH is not being used by curl, it is not clear at this time how to provide
+support for ECH. One option would seem to be to extend the ``c-ares`` library
+to support HTTPS RRs, but in that case it is not now clear whether such
+changes would be attractive to the ``c-ares`` maintainers, nor whether the
+"tag=value" extensibility inherent in the HTTPS/SVCB specification is a good
+match for the ``c-ares`` approach of defining structures specific to decoded
+answers for each supported RRtype. We are also not sure how many downstream
+curl deployments actually make use of the ``c-ares`` library, which would
+affect the utility of such changes. Another option might be to consider using
+some other generic DNS library that does support HTTPS RRs, but it is unclear
+if such a library could or would be used by all or almost all curl builds and
+downstream releases of curl.
+
+Our current conclusion is that doing the above is likely best left until we
+have some experience with the "using DoH" approach, so we are going to punt on
+this for now.
+
+### Debugging
+
+Just a note to self as remembering this is a nuisance:
+
+```sh
+LD_LIBRARY_PATH=$HOME/code/openssl:./lib/.libs gdb ./src/.libs/curl
+```
+
+### Localhost testing
+
+It can be useful to be able to run against a localhost OpenSSL ``s_server``
+for testing. We have published instructions for such
+[localhost tests](https://github.com/defo-project/ech-dev-utils/blob/main/howtos/localhost-tests.md)
+in another repository. Once you have that set up, you can start a server
+and then run curl against that:
+
+```sh
+cd $HOME/code/ech-dev-utils
+./scripts/echsvr.sh -d
+...
+```
+
+The ``echsvr.sh`` script supports many ECH-related options. Use ``echsvr.sh -h``
+for details.
+
+In another window:
+
+```sh
+cd $HOME/code/curl/
+./src/curl -vvv --insecure  --connect-to foo.example.com:8443:localhost:8443  --ech ecl:AD7+DQA6uwAgACBix2B78sX+EQhEbxMspDOc8Z3xVS5aQpYP0Cxpc2AWPAAEAAEAAQALZXhhbXBsZS5jb20AAA==
+```
+
+### Automated use of ``retry_configs`` not supported so far...
+
+As of now we have not added support for using ``retry_config`` handling in the
+application - for a command line tool, one can just use ``dig`` (or ``kdig``)
+to get the HTTPS RR and pass the ECHConfigList from that on the command line,
+if needed, or one can access the value from command line output in verbose more
+and then reuse that in another invocation.
+
+Both our OpenSSL fork and BoringSSL/AWS-LC have APIs for both controlling GREASE
+and accessing and logging ``retry_configs``, it seems wolfSSL has neither.
+
+### Testing ECH
+
+We have yet to add a robust test setup for ECH as that requires an ECH-enabled
+test server.
+
+We have added two basic tests though, aiming to ensure that the client sends a
+GREASE or real ECH extension when requested, and reacts correctly to the
+failure of ECH in the latter case. (Given that `stunnel` has no ECH support.)
+
+As with other similar tests, those tests require the `stunnel` tool be
+installed. On Ubuntu `sudo apt install stunnel4` achieves that.
+
+The test cases are:
+
+- data/test4000: GREASE ECH, expected result: connection succeeds
+- data/test4001: real ECH, connection fails with error 101 (ECH required)

+# Experimental
+
+Some features and functionality in curl and libcurl are considered
+**EXPERIMENTAL**.
+
+Experimental support in curl means:
+
+1. Experimental features are provided to allow users to try them out and
+   provide feedback on functionality and API etc before they ship and get
+   "carved in stone".
+2. You must enable the feature when invoking configure as otherwise curl is
+   not built with the feature present.
+3. We strongly advise against using this feature in production.
+4. **We reserve the right to change behavior** of the feature without sticking
+   to our API/ABI rules as we do for regular features, as long as it is marked
+   experimental.
+5. Experimental features are clearly marked so in documentation. Beware.
+
+## Graduation
+
+1. Each experimental feature should have a set of documented requirements of
+   what is needed for that feature to graduate. Graduation means being removed
+   from the list of experiments.
+2. An experiment should NOT graduate if it needs test cases to be disabled,
+   unless they are for minor features that are clearly documented as not
+   provided by the experiment and then the disabling should be managed inside
+   each affected test case.
+
+## Experimental features right now
+
+###  HTTP/3 support (non-ngtcp2 backends)
+
+Graduation requirements:
+
+- The used libraries should be considered out-of-beta with a reasonable
+  expectation of a stable API going forward.
+
+- Using HTTP/3 with the given build should perform without risking busy-loops
+
+### The Rustls backend
+
+Graduation requirements:
+
+- a reasonable expectation of a stable API going forward.
+
+## ECH
+
+Use of the HTTPS resource record and Encrypted Client Hello (ECH) when using
+DoH
+
+Graduation requirements:
+
+- ECH support exists in at least one widely used TLS library apart from
+  BoringSSL and wolfSSL.
+
+- feedback from users saying that ECH works for their use cases
+
+- it has been given time to mature, so no earlier than April 2025 (twelve
+  months after being added here)
+
+## SSL session import/export
+
+Import/Export of SSL sessions tickets in libcurl and curl command line
+option '--ssl-session <filename>' for faster TLS handshakes and use
+of TLSv1.3/QUIC Early Data (0-RTT).
+
+Graduation requirements:
+
+- the implementation is considered safe
+
+- feedback from users saying that session export works for their use cases
+
+## HTTPS RR
+
+HTTPS records support is a requirement for ECH but is provided as a
+stand-alone feature that is itself considered EXPERIMENTAL.
+
+Graduation requirements:
+
+- HTTPS records work for DoH, c-ares and the threaded resolver
+
+- HTTPS records can control ALPN and port number, at least
+
+- There are options to control HTTPS use

+
+# Decision making in the curl project
+
+A rough guide to how we make decisions and who does what.
+
+## BDFL
+
+This project was started by and has to some extent been pushed forward over
+the years with Daniel Stenberg as the driving force. It matches a standard
+BDFL (Benevolent Dictator For Life) style project.
+
+This setup has been used due to convenience and the fact that it has worked
+fine this far. It is not because someone thinks of it as a superior project
+leadership model. It also only works as long as Daniel manages to listen in to
+what the project and the general user population wants and expects from us.
+
+## Legal entity
+
+There is no legal entity. The curl project is just a bunch of people scattered
+around the globe with the common goal to produce source code that creates
+great products. We are not part of any umbrella organization and we are not
+located in any specific country. We are totally independent.
+
+The copyrights in the project are owned by the individuals and organizations
+that wrote those parts of the code.
+
+## Decisions
+
+The curl project is not a democracy, but everyone is entitled to state their
+opinion and may argue for their sake within the community.
+
+All and any changes that have been done or are done are eligible to bring up
+for discussion, to object to or to praise. Ideally, we find consensus for the
+appropriate way forward in any given situation or challenge.
+
+If there is no obvious consensus, a maintainer who's knowledgeable in the
+specific area takes an "executive" decision that they think is the right for
+the project.
+
+## Donations
+
+Donating plain money to curl is best done to curl's [Open Collective
+fund](https://opencollective.com/curl). Open Collective is a US based
+non-profit organization that holds on to funds for us. This fund is then used
+for paying the curl security bug bounties, to reimburse project related
+expenses etc.
+
+Donations to the project can also come in the form of server hosting, providing
+services and paying for people to work on curl related code etc. Usually, such
+donations are services paid for directly by the sponsors.
+
+We grade sponsors in a few different levels and if they meet the criteria,
+they can be mentioned on the Sponsors page on the curl website.
+
+## Commercial Support
+
+The curl project does not do or offer commercial support. It only hosts
+mailing lists, runs bug trackers etc to facilitate communication and work.
+
+However, Daniel works for wolfSSL and we offer commercial curl support there.
+
+# Key roles
+
+## User
+
+Someone who uses or has used curl or libcurl.
+
+## Contributor
+
+Someone who has helped the curl project, who has contributed to bring it
+forward. Contributing could be to provide advice, debug a problem, file a bug
+report, run test infrastructure or writing code etc.
+
+## Commit author
+
+Sometimes also called 'committer'. Someone who has authored a commit in the
+curl source code repository. Committers are recorded as `Author` in git.
+
+## Maintainers
+
+A maintainer in the curl project is an individual who has been given
+permissions to push commits to one of the git repositories.
+
+Maintainers are free to push commits to the repositories at they see fit.
+Maintainers are however expected to listen to feedback from users and any
+change that is non-trivial in size or nature *should* be brought to the
+project as a Pull-Request (PR) to allow others to comment/object before merge.
+
+## Former maintainers
+
+A maintainer who stops being active in the project gets their push permissions
+removed at some point. We do this for security reasons but also to make sure
+that we always have the list of maintainers as "the team that push stuff to
+curl".
+
+Getting push permissions removed is not a punishment. Everyone who ever worked
+on maintaining curl is considered a hero, for all time hereafter.
+
+## Security team members
+
+We have a security team. That is the team of people who are subscribed to the
+curl-security mailing list; the receivers of security reports from users and
+developers. This list of people varies over time but they are all skilled
+developers familiar with the curl project.
+
+The security team works best when it consists of a small set of active
+persons. We invite new members when the team seems to need it, and we also
+expect to retire security team members as they "drift off" from the project or
+just find themselves unable to perform their duties there.
+
+## Core team
+
+There is a curl core team. It currently has the same set of members as the
+security team. It can also be reached on the security email address.
+
+The core team nominates and invites new members to the team when it sees fit.
+There is no open member voting or formal ways to be a candidate. Active
+participants in the curl project who want to join the core team can ask to
+join.
+
+The core team is a board of advisors. It deals with project management
+subjects that need confidentiality or for other reasons cannot be dealt with
+and discussed in the open (for example reports of code of conduct violations).
+Project matters should always as far as possible be discussed on open mailing
+lists.
+
+## Server admins
+
+We run a web server, a mailing list and more on the curl project's primary
+server. That physical machine is owned and run by Haxx. Daniel is the primary
+admin of all things curl related server stuff, but Björn Stenberg and Linus
+Feltzing serve as backup admins for when Daniel is gone or unable.
+
+The primary server is paid for by Haxx. The machine is physically located in a
+server bunker in Stockholm Sweden, operated by the company Glesys.
+
+The website contents are served to the web via Fastly and Daniel is the
+primary curl contact with Fastly.
+
+## BDFL
+
+That is Daniel.
+
+# Maintainers
+
+A curl maintainer is a project volunteer who has the authority and rights to
+merge changes into a git repository in the curl project.
+
+Anyone can aspire to become a curl maintainer.
+
+### Duties
+
+There are no mandatory duties. We hope and wish that maintainers consider
+reviewing patches and help merging them, especially when the changes are
+within the area of personal expertise and experience.
+
+### Requirements
+
+- only merge code that meets our quality and style guide requirements.
+- *never* merge code without doing a PR first, unless the change is "trivial"
+- if in doubt, ask for input/feedback from others
+
+### Recommendations
+
+- we require two-factor authentication enabled on your GitHub account to
+  reduce risk of malicious source code tampering
+- consider enabling signed git commits for additional verification of changes
+
+### Merge advice
+
+When you are merging patches/pull requests...
+
+- make sure the commit messages follow our template
+- squash patch sets into a few logical commits even if the PR did not, if
+  necessary
+- avoid the "merge" button on GitHub, do it "manually" instead to get full
+  control and full audit trail (GitHub leaves out you as "Committer:")
+- remember to credit the reporter and the helpers.
+
+## Who are maintainers?
+
+The [list of maintainers](https://github.com/orgs/curl/people). Be aware that
+the level of presence and activity in the project vary greatly between
+different individuals and over time.
+
+### Become a maintainer?
+
+If you think you can help making the project better by shouldering some
+maintaining responsibilities, then please get in touch.
+
+You are expected to be familiar with the curl project and its ways of working.
+You need to have gotten a few quality patches merged as a proof of this.
+
+### Stop being a maintainer
+
+If you (appear to) not be active in the project anymore, you may be removed as
+a maintainer. Thank you for your service.

+
+# How to get started helping out in the curl project
+
+We are always in need of more help. If you are new to the project and are
+looking for ways to contribute and help out, this document aims to give a few
+good starting points.
+
+You may subscribe to the [curl-library mailing
+list](https://lists.haxx.se/listinfo/curl-library) to keep track of the
+current discussion topics; or if you are registered on GitHub, you can use the
+[Discussions section](https://github.com/curl/curl/discussions) on the main
+curl repository.
+
+## Scratch your own itch
+
+One of the best ways is to start working on any problems or issues you have
+found yourself or perhaps got annoyed at in the past. It can be a spelling
+error in an error text or a weirdly phrased section in a man page. Hunt it
+down and report the bug. Or make your first pull request with a fix for that.
+
+## Smaller tasks
+
+Some projects mark small issues as "beginner friendly", "bite-sized" or
+similar. We do not do that in curl since such issues never linger around long
+enough. Simple issues get handled fast.
+
+If you are looking for a smaller or simpler task in the project to help out
+with as an entry-point into the project, perhaps because you are a newcomer or
+even maybe not a terribly experienced developer, here's our advice:
+
+ - Read through this document to get a grasp on a general approach to use
+ - Consider adding a test case for something not currently tested (correctly)
+ - Consider updating or adding documentation
+ - One way to get started gently in the project, is to participate in an
+   existing issue/PR and help out by reproducing the issue, review the code in
+   the PR etc.
+
+## Help wanted
+
+In the issue tracker we occasionally mark bugs with [help
+wanted](https://github.com/curl/curl/labels/help%20wanted), as a sign that the
+bug is acknowledged to exist and that there is nobody known to work on this
+issue for the moment. Those are bugs that are fine to "grab" and provide a
+pull request for. The complexity level of these of course varies, so pick one
+that piques your interest.
+
+## Work on known bugs
+
+Some bugs are known and have not yet received attention and work enough to get
+fixed. We collect such known existing flaws in the
+[KNOWN_BUGS](https://curl.se/docs/knownbugs.html) page. Many of them link
+to the original bug report with some additional details, but some may also
+have aged a bit and may require some verification that the bug still exists in
+the same way and that what was said about it in the past is still valid.
+
+## Fix autobuild problems
+
+On the [autobuilds page](https://curl.se/dev/builds.html) we show a
+collection of test results from the automatic curl build and tests that are
+performed by volunteers. Fixing compiler warnings and errors shown there is
+something we value greatly. Also, if you own or run systems or architectures
+that are not already tested in the autobuilds, we also appreciate more
+volunteers running builds automatically to help us keep curl portable.
+
+## TODO items
+
+Ideas for features and functions that we have considered worthwhile to
+implement and provide are kept in the
+[TODO](https://curl.se/docs/todo.html) file. Some of the ideas are
+rough. Some are well thought out. Some probably are not really suitable
+anymore.
+
+Before you invest a lot of time on a TODO item, do bring it up for discussion
+on the mailing list. For discussion on applicability but also for ideas and
+brainstorming on specific ways to do the implementation etc.
+
+## You decide
+
+You can also come up with a completely new thing you think we should do. Or
+not do. Or fix. Or add to the project. You then either bring it to the mailing
+list first to see if people shoot down the idea at once, or you bring a first
+draft of the idea as a pull request and take the discussion there around the
+specific implementation. Either way is fine.
+
+## CONTRIBUTE
+
+We offer [guidelines](https://curl.se/dev/contribute.html) that are suitable
+to be familiar with before you decide to contribute to curl. If you are used
+to open source development, you probably do not find many surprises there.

+
+How curl Became Like This
+=========================
+
+Towards the end of 1996, Daniel Stenberg was spending time writing an IRC bot
+for an Amiga related channel on EFnet. He then came up with the idea to make
+currency-exchange calculations available to Internet Relay Chat (IRC)
+users. All the necessary data were published on the Web; he just needed to
+automate their retrieval.
+
+1996
+----
+
+On November 11, 1996 the Brazilian developer Rafael Sagula wrote and released
+HttpGet version 0.1.
+
+Daniel extended this existing command-line open-source tool. After a few minor
+adjustments, it did just what he needed. The first release with Daniel's
+additions was 0.2, released on December 17, 1996. Daniel quickly became the
+new maintainer of the project.
+
+1997
+----
+
+HttpGet 0.3 was released in January 1997 and now it accepted HTTP URLs on the
+command line.
+
+HttpGet 1.0 was released on April 8 1997 with brand new HTTP proxy support.
+
+We soon found and fixed support for getting currencies over GOPHER. Once FTP
+download support was added, the name of the project was changed and urlget 2.0
+was released in August 1997. The http-only days were already passed.
+
+Version 2.2 was released on August 14 1997 and introduced support to build for
+and run on Windows and Solaris.
+
+November 24 1997: Version 3.1 added FTP upload support.
+
+Version 3.5 added support for HTTP POST.
+
+1998
+----
+
+February 4: urlget 3.10
+
+February 9: urlget 3.11
+
+March 14: urlget 3.12 added proxy authentication.
+
+The project slowly grew bigger. With upload capabilities, the name was once
+again misleading and a second name change was made. On March 20, 1998 curl 4
+was released. (The version numbering from the previous names was kept.)
+
+(Unrelated to this project a company called Curl Corporation registered a US
+trademark on the name "CURL" on May 18 1998. That company had then already
+registered the curl.com domain back in November of the previous year. All this
+was revealed to us much later.)
+
+SSL support was added, powered by the SSLeay library.
+
+August: first announcement of curl on freshmeat.net.
+
+October: with the curl 4.9 release and the introduction of cookie support,
+curl was no longer released under the GPL license. Now we are at 4000 lines of
+code, we switched over to the MPL license to restrict the effects of
+"copyleft".
+
+November: configure script and reported successful compiles on several
+major operating systems. The never-quite-understood -F option was added and
+curl could now simulate quite a lot of a browser. TELNET support was added.
+
+curl 5 was released in December 1998 and introduced the first ever curl man
+page. People started making Linux RPM packages out of it.
+
+1999
+----
+
+January: DICT support added.
+
+OpenSSL took over and SSLeay was abandoned.
+
+May: first Debian package.
+
+August: LDAP:// and FILE:// support added. The curl website gets 1300 visits
+weekly. Moved site to curl.haxx.nu.
+
+September: Released curl 6.0. 15000 lines of code.
+
+December 28: added the project on Sourceforge and started using its services
+for managing the project.
+
+2000
+----
+
+Spring: major internal overhaul to provide a suitable library interface.
+The first non-beta release was named 7.1 and arrived in August. This offered
+the easy interface and turned out to be the beginning of actually getting
+other software and programs to be based on and powered by libcurl. Almost
+20000 lines of code.
+
+June: the curl site moves to "curl.haxx.se"
+
+August, the curl website gets 4000 visits weekly.
+
+The PHP guys adopted libcurl already the same month, when the first ever third
+party libcurl binding showed up. CURL has been a supported module in PHP since
+the release of PHP 4.0.2. This would soon get followers. More than 16
+different bindings exist at the time of this writing.
+
+September: kerberos4 support was added.
+
+November: started the work on a test suite for curl. It was later re-written
+from scratch again. The libcurl major SONAME number was set to 1.
+
+2001
+----
+
+January: Daniel released curl 7.5.2 under a new license again: MIT (or
+MPL). The MIT license is extremely liberal and can be combined with GPL
+in other projects. This would finally put an end to the "complaints" from
+people involved in GPLed projects that previously were prohibited from using
+libcurl while it was released under MPL only. (Due to the fact that MPL is
+deemed "GPL incompatible".)
+
+March 22: curl supports HTTP 1.1 starting with the release of 7.7. This
+also introduced libcurl's ability to do persistent connections. 24000 lines of
+code. The libcurl major SONAME number was bumped to 2 due to this overhaul.
+The first experimental ftps:// support was added.
+
+August: The curl website gets 8000 visits weekly. Curl Corporation contacted
+Daniel to discuss "the name issue". After Daniel's reply, they have never
+since got back in touch again.
+
+September: libcurl 7.9 introduces cookie jar and `curl_formadd()`. During the
+forthcoming 7.9.x releases, we introduced the multi interface slowly and
+without many whistles.
+
+September 25: curl (7.7.2) is bundled in Mac OS X (10.1) for the first time. It was
+already becoming more and more of a standard utility of Linux distributions
+and a regular in the BSD ports collections.
+
+2002
+----
+
+June: the curl website gets 13000 visits weekly. curl and libcurl is
+35000 lines of code. Reported successful compiles on more than 40 combinations
+of CPUs and operating systems.
+
+To estimate the number of users of the curl tool or libcurl library is next to
+impossible. Around 5000 downloaded packages each week from the main site gives
+a hint, but the packages are mirrored extensively, bundled with numerous OS
+distributions and otherwise retrieved as part of other software.
+
+October 1: with the release of curl 7.10 it is released under the MIT license
+only.
+
+Starting with 7.10, curl verifies SSL server certificates by default.
+
+2003
+----
+
+January: Started working on the distributed curl tests. The autobuilds.
+
+February: the curl site averages at 20000 visits weekly. At any given moment,
+there is an average of 3 people browsing the website.
+
+Multiple new authentication schemes are supported: Digest (May), NTLM (June)
+and Negotiate (June).
+
+November: curl 7.10.8 is released. 45000 lines of code. ~55000 unique visitors

+# HSTS support
+
+HTTP Strict-Transport-Security. Added as experimental in curl
+7.74.0. Supported "for real" since 7.77.0.
+
+## Standard
+
+[HTTP Strict Transport Security](https://datatracker.ietf.org/doc/html/rfc6797)
+
+## Behavior
+
+libcurl features an in-memory cache for HSTS hosts, so that subsequent
+HTTP-only requests to a hostname present in the cache gets internally
+"redirected" to the HTTPS version.
+
+## `curl_easy_setopt()` options:
+
+ - `CURLOPT_HSTS_CTRL` - enable HSTS for this easy handle
+ - `CURLOPT_HSTS` - specify filename where to store the HSTS cache on close
+  (and possibly read from at startup)
+
+## curl command line options
+
+ - `--hsts [filename]` - enable HSTS, use the file as HSTS cache. If filename
+   is `""` (no length) then no file is used, only in-memory cache.
+
+## HSTS cache file format
+
+Lines starting with `#` are ignored.
+
+For each hsts entry:
+
+    [host name] "YYYYMMDD HH:MM:SS"
+
+The `[host name]` is dot-prefixed if it includes subdomains.
+
+The time stamp is when the entry expires.
+
+## Possible future additions
+
+ - `CURLOPT_HSTS_PRELOAD` - provide a set of HSTS hostnames to load first
+ - ability to save to something else than a file

+# HTTP Cookies
+
+## Cookie overview
+
+  Cookies are `name=contents` pairs that an HTTP server tells the client to
+  hold and then the client sends back those to the server on subsequent
+  requests to the same domains and paths for which the cookies were set.
+
+  Cookies are either "session cookies" which typically are forgotten when the
+  session is over which is often translated to equal when browser quits, or
+  the cookies are not session cookies they have expiration dates after which
+  the client throws them away.
+
+  Cookies are set to the client with the Set-Cookie: header and are sent to
+  servers with the Cookie: header.
+
+  For a long time, the only spec explaining how to use cookies was the
+  original [Netscape spec from 1994](https://curl.se/rfc/cookie_spec.html).
+
+  In 2011, [RFC 6265](https://datatracker.ietf.org/doc/html/rfc6265) was finally
+  published and details how cookies work within HTTP. In 2016, an update which
+  added support for prefixes was
+  [proposed](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-cookie-prefixes-00),
+  and in 2017, another update was
+  [drafted](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-cookie-alone-01)
+  to deprecate modification of 'secure' cookies from non-secure origins. Both
+  of these drafts have been incorporated into a proposal to
+  [replace](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-rfc6265bis-11)
+  RFC 6265. Cookie prefixes and secure cookie modification protection has been
+  implemented by curl.
+
+  curl considers `http://localhost` to be a *secure context*, meaning that it
+  allows and uses cookies marked with the `secure` keyword even when done over
+  plain HTTP for this host. curl does this to match how popular browsers work
+  with secure cookies.
+
+## Super cookies
+
+  A single cookie can be set for a domain that matches multiple hosts. Like if
+  set for `example.com` it gets sent to both `aa.example.com` as well as
+  `bb.example.com`.
+
+  A challenge with this concept is that there are certain domains for which
+  cookies should not be allowed at all, because they are *Public
+  Suffixes*. Similarly, a client never accepts cookies set directly for the
+  top-level domain like for example `.com`. Cookies set for *too broad*
+  domains are generally referred to as *super cookies*.
+
+  If curl is built with PSL (**Public Suffix List**) support, it detects and
+  discards cookies that are specified for such suffix domains that should not
+  be allowed to have cookies.
+
+  if curl is *not* built with PSL support, it has no ability to stop super
+  cookies.
+
+## Cookies saved to disk
+
+  Netscape once created a file format for storing cookies on disk so that they
+  would survive browser restarts. curl adopted that file format to allow
+  sharing the cookies with browsers, only to see browsers move away from that
+  format. Modern browsers no longer use it, while curl still does.
+
+  The Netscape cookie file format stores one cookie per physical line in the
+  file with a bunch of associated meta data, each field separated with
+  TAB. That file is called the cookie jar in curl terminology.
+
+  When libcurl saves a cookie jar, it creates a file header of its own in
+  which there is a URL mention that links to the web version of this document.
+
+## Cookie file format
+
+  The cookie file format is text based and stores one cookie per line. Lines
+  that start with `#` are treated as comments. An exception is lines that
+  start with `#HttpOnly_`, which is a prefix for cookies that have the
+  `HttpOnly` attribute set.
+
+  Each line that specifies a single cookie consists of seven text fields
+  separated with TAB characters. A valid line must end with a newline
+  character.
+
+### Fields in the file
+
+  Field number, what type and example data and the meaning of it:
+
+  0. string `example.com` - the domain name
+  1. boolean `FALSE` - include subdomains
+  2. string `/foobar/` - path
+  3. boolean `TRUE` - send/receive over HTTPS only
+  4. number `1462299217` - expires at - seconds since Jan 1st 1970, or 0
+  5. string `person` - name of the cookie
+  6. string `daniel` - value of the cookie
+
+## Cookies with curl the command line tool
+
+  curl has a full cookie "engine" built in. If you just activate it, you can
+  have curl receive and send cookies exactly as mandated in the specs.
+
+  Command line options:
+
+  [`-b, --cookie`](https://curl.se/docs/manpage.html#-b)
+
+  tell curl a file to read cookies from and start the cookie engine, or if it
+  is not a file it passes on the given string. `-b name=var` works and so does
+  `-b cookiefile`.
+
+  [`-j, --junk-session-cookies`](https://curl.se/docs/manpage.html#-j)
+
+  when used in combination with -b, it skips all "session cookies" on load so
+  as to appear to start a new cookie session.
+
+  [`-c, --cookie-jar`](https://curl.se/docs/manpage.html#-c)
+
+  tell curl to start the cookie engine and write cookies to the given file
+  after the request(s)
+
+## Cookies with libcurl
+
+libcurl offers several ways to enable and interface the cookie engine. These
+options are the ones provided by the native API. libcurl bindings may offer
+access to them using other means.
+
+[`CURLOPT_COOKIE`](https://curl.se/libcurl/c/CURLOPT_COOKIE.html)
+
+Is used when you want to specify the exact contents of a cookie header to
+send to the server.
+
+[`CURLOPT_COOKIEFILE`](https://curl.se/libcurl/c/CURLOPT_COOKIEFILE.html)
+
+Tell libcurl to activate the cookie engine, and to read the initial set of
+cookies from the given file. Read-only.
+
+[`CURLOPT_COOKIEJAR`](https://curl.se/libcurl/c/CURLOPT_COOKIEJAR.html)
+
+Tell libcurl to activate the cookie engine, and when the easy handle is
+closed save all known cookies to the given cookie jar file. Write-only.
+
+[`CURLOPT_COOKIELIST`](https://curl.se/libcurl/c/CURLOPT_COOKIELIST.html)
+
+Provide detailed information about a single cookie to add to the internal
+storage of cookies. Pass in the cookie as an HTTP header with all the
+details set, or pass in a line from a Netscape cookie file. This option can
+also be used to flush the cookies etc.
+
+[`CURLOPT_COOKIESESSION`](https://curl.se/libcurl/c/CURLOPT_COOKIESESSION.html)
+
+Tell libcurl to ignore all cookies it is about to load that are session
+cookies.
+
+[`CURLINFO_COOKIELIST`](https://curl.se/libcurl/c/CURLINFO_COOKIELIST.html)
+
+Extract cookie information from the internal cookie storage as a linked
+list.
+
+## Cookies with JavaScript
+
+These days a lot of the web is built up by JavaScript. The web browser loads
+complete programs that render the page you see. These JavaScript programs
+can also set and access cookies.
+
+Since curl and libcurl are plain HTTP clients without any knowledge of or
+capability to handle JavaScript, such cookies are not detected or used.
+
+Often, if you want to mimic what a browser does on such websites, you can
+record web browser HTTP traffic when using such a site and then repeat the
+cookie operations using curl or libcurl.

+
+## Resources
+
+[HTTP/3 Explained](https://http3-explained.haxx.se/en/) - the online free
+book describing the protocols involved.
+
+[quicwg.org](https://quicwg.org/) - home of the official protocol drafts
+
+## QUIC libraries
+
+QUIC libraries we are using:
+
+[ngtcp2](https://github.com/ngtcp2/ngtcp2)
+
+[quiche](https://github.com/cloudflare/quiche) - **EXPERIMENTAL**
+
+[OpenSSL 3.2+ QUIC](https://github.com/openssl/openssl) - **EXPERIMENTAL**
+
+## Experimental
+
+HTTP/3 support in curl is considered **EXPERIMENTAL** until further notice
+when built to use *quiche*. Only the *ngtcp2* backend is not experimental.
+
+Further development and tweaking of the HTTP/3 support in curl happens in the
+master branch using pull-requests, just like ordinary changes.
+
+To fix before we remove the experimental label:
+
+ - the used QUIC library needs to consider itself non-beta
+ - it is fine to "leave" individual backends as experimental if necessary
+
+# ngtcp2 version
+
+Building curl with ngtcp2 involves 3 components: `ngtcp2` itself, `nghttp3` and a QUIC supporting TLS library. The supported TLS libraries are covered below.
+
+While any version of `ngtcp2` and `nghttp3` from v1.0.0 on are expected to
+work, using the latest versions often brings functional and performance
+improvements.
+
+The build examples use `$NGHTTP3_VERSION` and `$NGTCP2_VERSION` as placeholders
+for the version you build.
+
+## Build with OpenSSL
+
+OpenSSL v3.5.0+ offers APIs for integration with *ngtcp2* v1.12.0+. Earlier
+versions do not work.
+
+Build OpenSSL (version 3.5.0 or newer):
+
+     % git clone --quiet --depth=1 -b openssl-$OPENSSL_VERSION https://github.com/openssl/openssl
+     % cd openssl
+     % ./config --prefix=<somewhere1> --libdir=lib
+     % make
+     % make install
+
+Build nghttp3:
+
+     % cd ..
+     % git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
+     % cd nghttp3
+     % git submodule update --init
+     % autoreconf -fi
+     % ./configure --prefix=<somewhere2> --enable-lib-only
+     % make
+     % make install
+
+Build ngtcp2:
+
+     % cd ..
+     % git clone -b $NGTCP2_VERSION https://github.com/ngtcp2/ngtcp2
+     % cd ngtcp2
+     % autoreconf -fi
+     % ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3> --enable-lib-only --with-openssl
+     % make
+     % make install
+
+Build curl:
+
+     % cd ..
+     % git clone https://github.com/curl/curl
+     % cd curl
+     % autoreconf -fi
+     % LDFLAGS="-Wl,-rpath,<somewhere1>/lib" ./configure PKG_CONFIG_PATH=<ngtcp2-root>/lib/pkgconfig --with-openssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2
+     % make
+     % make install
+
+## Build with quictls
+
+OpenSSL before version 3.5 does not offer the required APIs for building a
+QUIC client. You need to use a TLS library that has such APIs and that works
+with *ngtcp2*.
+
+Build quictls (any `+quic` tagged version works):
+
+     % git clone --depth 1 -b openssl-3.1.4+quic https://github.com/quictls/openssl
+     % cd openssl
+     % ./config enable-tls1_3 --prefix=<somewhere1> --libdir=lib
+     % make
+     % make install
+
+Build nghttp3:
+
+     % cd ..
+     % git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
+     % cd nghttp3
+     % git submodule update --init
+     % autoreconf -fi
+     % ./configure --prefix=<somewhere2> --enable-lib-only
+     % make
+     % make install
+
+Build ngtcp2:
+
+     % cd ..
+     % git clone -b $NGTCP2_VERSION https://github.com/ngtcp2/ngtcp2
+     % cd ngtcp2
+     % autoreconf -fi
+     % ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3> --enable-lib-only
+     % make
+     % make install
+
+Build curl:
+
+     % cd ..
+     % git clone https://github.com/curl/curl
+     % cd curl
+     % autoreconf -fi
+     % LDFLAGS="-Wl,-rpath,<somewhere1>/lib" ./configure PKG_CONFIG_PATH=<ngtcp2-root>/lib/pkgconfig --with-openssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2
+     % make
+     % make install
+
+## Build with GnuTLS
+
+Build GnuTLS:
+
+     % git clone --depth 1 https://gitlab.com/gnutls/gnutls.git
+     % cd gnutls
+     % ./bootstrap
+     % ./configure --prefix=<somewhere1>
+     % make
+     % make install
+
+Build nghttp3:
+
+     % cd ..
+     % git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
+     % cd nghttp3

+# quiche version
+
+quiche support is **EXPERIMENTAL**
+
+Since the quiche build manages its dependencies, curl can be built against the latest version. You are *probably* able to build against their main branch, but in case of problems, we recommend their latest release tag.
+
+## Build
+
+Build quiche and BoringSSL:
+
+     % git clone --recursive -b 0.22.0 https://github.com/cloudflare/quiche
+     % cd quiche
+     % cargo build --package quiche --release --features ffi,pkg-config-meta,qlog
+     % ln -s libquiche.so target/release/libquiche.so.0
+     % mkdir quiche/deps/boringssl/src/lib
+     % ln -vnf $(find target/release -name libcrypto.a -o -name libssl.a) quiche/deps/boringssl/src/lib/
+
+Build curl:
+
+     % cd ..
+     % git clone https://github.com/curl/curl
+     % cd curl
+     % autoreconf -fi
+     % ./configure LDFLAGS="-Wl,-rpath,$PWD/../quiche/target/release" --with-openssl=$PWD/../quiche/quiche/deps/boringssl/src --with-quiche=$PWD/../quiche/target/release
+     % make
+     % make install
+
+ If `make install` results in `Permission denied` error, you need to prepend
+ it with `sudo`.
+
+# OpenSSL version
+
+QUIC support is **EXPERIMENTAL**
+
+Use OpenSSL 3.3.1 or newer (QUIC support was added in 3.3.0, with
+shortcomings on some platforms like macOS). 3.4.1 or newer is recommended.
+Build via:
+
+     % cd ..
+     % git clone -b $OPENSSL_VERSION https://github.com/openssl/openssl
+     % cd openssl
+     % ./config enable-tls1_3 --prefix=<somewhere> --libdir=lib
+     % make
+     % make install
+
+Build nghttp3:
+
+     % cd ..
+     % git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
+     % cd nghttp3
+     % git submodule update --init
+     % autoreconf -fi
+     % ./configure --prefix=<somewhere2> --enable-lib-only
+     % make
+     % make install
+
+Build curl:
+
+     % cd ..
+     % git clone https://github.com/curl/curl
+     % cd curl
+     % autoreconf -fi
+     % LDFLAGS="-Wl,-rpath,<somewhere>/lib" ./configure --with-openssl=<somewhere> --with-openssl-quic --with-nghttp3=<somewhere2>
+     % make
+     % make install
+
+You can build curl with cmake:
+
+     % cd ..
+     % git clone https://github.com/curl/curl
+     % cd curl
+     % cmake -B bld -DCURL_USE_OPENSSL=ON -DUSE_OPENSSL_QUIC=ON
+     % cmake --build bld
+     % cmake --install bld
+
+ If `make install` results in `Permission denied` error, you need to prepend
+ it with `sudo`.
+
+# `--http3`
+
+Use only HTTP/3:
+
+     % curl --http3-only https://example.org:4433/
+
+Use HTTP/3 with fallback to HTTP/2 or HTTP/1.1 (see "HTTPS eyeballing" below):
+
+     % curl --http3 https://example.org:4433/
+
+Upgrade via Alt-Svc:
+
+     % curl --alt-svc altsvc.cache https://curl.se/
+
+See this [list of public HTTP/3 servers](https://bagder.github.io/HTTP3-test/)
+
+### HTTPS eyeballing
+
+With option `--http3` curl attempts earlier HTTP versions as well should the
+connect attempt via HTTP/3 not succeed "fast enough". This strategy is similar
+to IPv4/6 happy eyeballing where the alternate address family is used in
+parallel after a short delay.
+
+The IPv4/6 eyeballing has a default of 200ms and you may override that via
+`--happy-eyeballs-timeout-ms value`. Since HTTP/3 is still relatively new, we
+decided to use this timeout also for the HTTP eyeballing - with a slight
+twist.
+
+The `happy-eyeballs-timeout-ms` value is the **hard** timeout, meaning after
+that time expired, a TLS connection is opened in addition to negotiate HTTP/2
+or HTTP/1.1. At half of that value - currently - is the **soft** timeout. The
+soft timeout fires, when there has been **no data at all** seen from the
+server on the HTTP/3 connection.
+
+So, without you specifying anything, the hard timeout is 200ms and the soft is 100ms:
+
+ * Ideally, the whole QUIC handshake happens and curl has an HTTP/3 connection
+   in less than 100ms.
+ * When QUIC is not supported (or UDP does not work for this network path), no
+   reply is seen and the HTTP/2 TLS+TCP connection starts 100ms later.
+ * In the worst case, UDP replies start before 100ms, but drag on. This starts
+   the TLS+TCP connection after 200ms.
+ * When the QUIC handshake fails, the TLS+TCP connection is attempted right
+   away. For example, when the QUIC server presents the wrong certificate.
+
+The whole transfer only fails, when **both** QUIC and TLS+TCP fail to
+handshake or time out.
+
+Note that all this happens in addition to IP version happy eyeballing. If the
+name resolution for the server gives more than one IP address, curl tries all
+those until one succeeds - just as with all other protocols. If those IP
+addresses contain both IPv6 and IPv4, those attempts happen, delayed, in
+parallel (the actual eyeballing).
+
+## Known Bugs
+
+Check out the [list of known HTTP3 bugs](https://curl.se/docs/knownbugs.html#HTTP3).
+
+# HTTP/3 Test server
+
+This is not advice on how to run anything in production. This is for
+development and experimenting.
+
+## Prerequisite(s)
+
+An existing local HTTP/1.1 server that hosts files. Preferably also a few huge
+ones. You can easily create huge local files like `truncate -s=8G 8GB` - they
+are huge but do not occupy that much space on disk since they are just big
+holes.
+
+In a Debian setup you can install apache2. It runs on port 80 and has a
+document root in `/var/www/html`. Download the 8GB file from apache with `curl
+localhost/8GB -o dev/null`
+
+In this description we setup and run an HTTP/3 reverse-proxy in front of the
+HTTP/1 server.
+
+## Setup
+
+You can select either or both of these server solutions.
+
+### nghttpx
+
+Get, build and install quictls, nghttp3 and ngtcp2 as described
+above.
+
+Get, build and install nghttp2:
+
+     % git clone https://github.com/nghttp2/nghttp2.git
+     % cd nghttp2
+     % autoreconf -fi
+     % PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/daniel/build-quictls/lib/pkgconfig:/home/daniel/build-nghttp3/lib/pkgconfig:/home/daniel/build-ngtcp2/lib/pkgconfig LDFLAGS=-L/home/daniel/build-quictls/lib CFLAGS=-I/home/daniel/build-quictls/include ./configure --enable-maintainer-mode --prefix=/home/daniel/build-nghttp2 --disable-shared --enable-app --enable-http3 --without-jemalloc --without-libxml2 --without-systemd
+     % make && make install
+
+Run the local h3 server on port 9443, make it proxy all traffic through to
+HTTP/1 on localhost port 80. For local toying, we can just use the test cert
+that exists in curl's test dir.
+
+     % CERT=/path/to/stunnel.pem
+     % $HOME/bin/nghttpx $CERT $CERT --backend=localhost,80 \
+      --frontend="localhost,9443;quic"
+
+### Caddy
+
+[Install Caddy](https://caddyserver.com/docs/install). For easiest use, the binary
+should be either in your PATH or your current directory.
+
+Create a `Caddyfile` with the following content:
+~~~
+localhost:7443 {
+  respond "Hello, world! you are using {http.request.proto}"
+}
+~~~
+
+Then run Caddy:
+
+     % ./caddy start
+
+Making requests to `https://localhost:7443` should tell you which protocol is being used.
+
+You can change the hard-coded response to something more useful by replacing `respond`
+with `reverse_proxy` or `file_server`, for example: `reverse_proxy localhost:80`

+# HTTPS RR
+
+[RFC 9460](https://datatracker.ietf.org/doc/html/rfc9460) documents the HTTPS
+DNS Resource Record.
+
+curl features **experimental** support for HTTPS RR.
+
+- The ALPN list from the record is parsed and used
+- The ECH field is stored - and used if ECH is enabled in the build
+- The port number is not used (Firefox supports it, Chrome does not)
+- The target name is not used
+- The IP addresses (`Ipv6hints`, `Ipv4hints`) from the HTTPS RR are not used
+- It only supports a single HTTPS RR per hostname
+- Hostnames without A/AAAA records but *with* HTTPS RR fails
+- consider service profiles where the RR provides different addresses for TCP
+  vs QUIC etc
+
+`HTTPSRR` is listed as a feature in the `curl -V` output if curl contains
+HTTPS RR support. If c-ares is not included in the build, the HTTPS RR support
+is limited to DoH.
+
+`asyn-rr` is listed as a feature in the `curl -V` output if c-ares is used for
+additional resolves in addition to a "normal" resolve done with the threaded
+resolver.
+
+The data extracted from the HTTPS RR is stored in the in-memory DNS cache to
+be reused on subsequent uses of the same hostnames.
+
+## limitations
+
+We have decided to work on the HTTPS RR support by following what seems to be
+(widely) used, and simply wait with implementing the details of the record
+that do not seem to be deployed. HTTPS RR is a DNS field with many odd corners
+and complexities and we might as well avoid them if no one seems to want them.
+
+## build
+
+    ./configure --enable-httpsrr
+
+or
+
+    cmake -DUSE_HTTPSRR=ON
+
+## ALPN
+
+The list of ALPN IDs is parsed but may not be completely respected because of
+what the HTTP version preference is set to, which is a problem we are working
+on. Also, getting an `HTTP/1.1` ALPN in the HTTPS RR field for an HTTP://
+transfer should imply switching to HTTPS, HSTS style. Which curl currently
+does not.
+
+## DoH
+
+When HTTPS RR is enabled in the curl build, The DoH code asks for an HTTPS
+record in addition to the A and AAAA records, and if an HTTPS RR answer is
+returned, curl parses it and stores the retrieved information.
+
+## Non-DoH
+
+If DoH is not used for name resolving in an HTTPS RR enabled build, we must
+provide the ability using the regular resolver backends. We use the c-ares DNS
+library for the HTTPS RR lookup. Version 1.28.0 or later.
+
+### c-ares
+
+If curl is built to use the c-ares library for name resolves, an HTTPS RR
+enabled build makes a request for the HTTPS RR in addition to the regular
+lookup.
+
+### Threaded resolver
+
+When built to use the threaded resolver, which is the default, an HTTPS RR
+build still needs a c-ares installation provided so that a separate request
+for the HTTPS record can be done in parallel to the regular getaddrinfo()
+call.
+
+This is done by specifying both c-ares and threaded resolver to configure:
+
+    ./configure --enable-ares=... --enable-threaded-resolver
+
+or to cmake:
+
+    cmake -DENABLE_ARES=ON -DENABLE_THREADED_RESOLVER=ON
+
+Because the HTTPS record is handled separately from the A/AAAA record
+retrieval, by a separate library, there is a small risk for discrepancies.
+
+When building curl using the threaded resolver with HTTPS RR support (using
+c-ares), the `curl -V` output looks exactly like a c-ares resolver build.
+
+## HTTPS RR Options
+
+Because curl is a low level transfer tool for which users sometimes want
+detailed control, we need to offer options to control HTTPS RR use.

+# Infrastructure in the curl project
+
+Overview of infrastructure we maintain, host and run in the project for the
+project.
+
+## git repository
+
+Since 2010, the main curl git repository has been hosted by GitHub, available
+at https://github.com/curl/curl.
+
+We also use the issue tracker, pull requests and discussions on GitHub.
+
+curl has an "enterprise account" on GitHub and is an "organization" on the
+site.
+
+We accept sponsorship via GitHub Sponsors.
+
+## CI services
+
+For every pull request and git push to the master repository, a number of
+build and testing jobs are run on a set of different CI services. The exact
+services vary over time. GitHub Actions and AppVeyor are the primary ones
+these days.
+
+## Test Clutch
+
+A [Test Clutch](https://github.com/dfandrich/testclutch) instance generates
+regular reports on curl CI test results at https://testclutch.curl.se/ as well
+as writing comments on curl pull requests whose tests have failed. The jobs
+are hosted on a Virtuozzo Application Platform PaaS instance and is managed by
+Dan Fandrich. The configuration code is available and managed at
+https://github.com/dfandrich/testclutch-curl-web
+
+## Autobuilds
+
+The curl autobuild system is a set of scripts that build and test curl and
+send all output logs back to the autobuild server. The results are
+continuously collected and visualized on the curl website at
+<https://curl.se/dev/builds.html>.
+
+The autobuild system and server is maintained by Daniel Stenberg.
+
+## OSS-Fuzz
+
+Google runs the [OSS-Fuzz](https://google.github.io/oss-fuzz/) project which
+also runs fuzzing on curl code, non-stop, in their infrastructure and they
+send us emails in the rare instances they actually find something.
+
+OSS-Fuzz notifies those that are members in the "curl team". Any curl
+maintainer who wants to is welcome to participate. It requires a Google
+account.
+
+## Coverity
+
+We regularly run our code through the [Coverity static code
+analyzer](https://scan.coverity.com/) thanks to them offering this service to
+us for free.
+
+## CodeSonar
+
+[CodeSonar](https://codesecure.com/our-products/codesonar/) analyzes the curl
+source code daily and emails Daniel Stenberg whenever it finds suspected
+problems in the source code. I hope and expect that we can invite other
+maintainers to access these reports soon.
+
+## Domain names
+
+The project runs services and website using a few different curl related
+domain names, including `curl.se` and `curl.dev`. Daniel Stenberg owns these
+domain names.
+
+Until a few years ago, the curl website was present at `curl.haxx.se`. The
+`haxx.se` domain is owned by Haxx AB, administrated by Daniel Stenberg. The
+curl.haxx.se name is meant to keep working and be redirecting to curl.se for
+the foreseeable future.
+
+## Websites
+
+The main curl website at `curl.se` is maintained by curl maintainers and the
+content is available and managed at https://github.com/curl/curl-www. The site
+updates from git and runs make every 20 minutes. Any change pushed to git can
+thus take up to 20 minutes until it takes effect on the origin server.
+
+The content on `curl.dev` is available and managed at
+https://github.com/curl/curl.dev/
+
+The content on `everything-curl.dev` is available and managed at
+https://github.com/curl/everything-curl/
+
+The machine hosting the website contents for these three sites is owned by
+Haxx AB and is primarily managed by Daniel Stenberg (co-owner of the Haxx
+company). The machine is physically located in Sweden.
+
+curl release tarballs are hosted on https://curl.se/download.html. They are
+uploaded there at release-time by the release manager.
+
+curl-for-win downloads are hosted on https://curl.se/windows and are uploaded
+to the server by Viktor Szakats.
+
+curl-for-QNX downloads are hosted on <https://curl.se/qnx> and are uploaded to
+the server by Daniel Stenberg.
+
+Daily release tarball-like snapshots are generated automatically and are
+provided for download at <https://curl.se/snapshots/>.
+
+CA certificate bundles are extracted from the Firefox source code, hosted by
+Mozilla and converted to PEM file format and is offered for download. The
+conversion checks for updates daily. The bundle is provided for download at
+<https://curl.se/docs/caextract.html>.
+
+There is an automated "download check bot" that runs twice daily to scan for
+available curl downloads to populate the curl download page appropriately with
+the correct updated information. The bot uses URLs and patterns for all
+download packages and is maintained in a database, maintained by Daniel
+Stenberg and Dan Fandrich.
+
+The TLS certificate for the origin curl web server is automatically updated
+from Let's Encrypt.
+
+## CDN
+
+Fastly runs the Content Delivery Network (CDN) that fronts all the curl
+websites. The CDN caches content that it gets from the origin server.
+Recently, roughly 99.99% of web requests are satisfied by the CDN without
+having to reach the origin.
+
+The CDN caches different content at different lengths depending on the
+content-type. The caching thus adds to the time for a change to have an effect
+on the site from the moment it gets pushed to the git repository.
+
+Using this setup, we provide four IPv4 addresses and eight IPv6 addresses for
+anycast access to the site. Should be snappy from virtually everywhere across
+the globe.
+
+The CDN servers support HTTP/1, HTTP/2 and HTTP/3. They set HSTS for a year.
+The `HTTP://` version of the site redirects to `HTTPS://`.
+
+Fastly manages the TLS certificates from Let's Encrypt for the servers they
+run on the behalf of curl.
+
+## Containers
+
+The curl project offer container builds of curl. The source repository for
+them is located at <https://github.com/curl/curl-container>.
+
+Container images are hosted at <https://quay.io/repository/curl/curl> and
+<https://hub.docker.com/r/curlimages/curl>
+
+## DNS
+
+The primary domain name, `curl.se` is managed by Kirei and is offered over
+fault-tolerant anycast servers. High availability and fast access for
+everyone.
+
+The actual physical DNS files and origin bind instance is managed by Daniel
+Stenberg.
+
+## Mailing lists
+
+The curl related mailing lists are hosted by Haxx AB on `lists.haxx.se` and
+are maintained by Daniel Stenberg. This includes the mailman2 and Postfix
+instances used for this.
+
+## Email
+
+We use a few rare additional curl related email aliases in the curl domains.
+They go through the mail server `mail.haxx.se` maintained by Daniel Stenberg
+
+## Bug-bounty
+
+We run a [bug-bounty](https://curl.se/docs/bugbounty.html) on HackerOne. The
+setup runs entirely at https://hackerone.com/curl.
+
+The money part for the bug bounty is sponsored by the [Internet Bug
+Bounty](https://hackerone.com/ibb).
+
+## Open Collective
+
+We use [Open Collective](https://opencollective.com/curl) as our "fiscal
+host". All money sent to and received by the curl project is managed by Open
+Collective.
+
+## Merchandise
+
+We have stickers, coffee mugs and coasters. They are managed by Daniel who
+sits on the inventory. The best way to get your hands on curl merchandise is
+to attend events where Daniel is physically.
+
+## Chat
+
+Some curl developers, maintainers, users and enthusiasts use IRC for real-time
+chat about curl and related topics. This done in the `#curl` channel on the
+`libra.chat` IRC network. **Daniel Stenberg** (`bagder`) is registered owner
+of the channel. We do not run any IRC servers or services ourselves.
+
+`curelbot` is a service in the channel that shows details about GitHub issues
+and pull requests when publicly mentioned using #[number]. The bot is run by
+user `TheAssassin`.
+
+There is a Matrix bridge to the IRC channel called `matrix.curl.se`. The
+bridge is setup and run by **Sergio Durigan Junior** and **Daniel Stenberg**.

+# Building with CMake
+
+This document describes how to configure, build and install curl and libcurl
+from source code using the CMake build tool. To build with CMake, you of
+course first have to install CMake. The minimum required version of CMake is
+specified in the file `CMakeLists.txt` found in the top of the curl source
+tree. Once the correct version of CMake is installed you can follow the
+instructions below for the platform you are building on.
+
+CMake builds can be configured either from the command line, or from one of
+CMake's GUIs.
+
+# Configuring
+
+A CMake configuration of curl is similar to the autotools build of curl.
+It consists of the following steps after you have unpacked the source.
+
+We recommend building with CMake on Windows. For instructions on migrating
+from the `projects/Windows` Visual Studio solution files, see
+[this section](#migrating-from-visual-studio-ide-project-files).
+
+## Using `cmake`
+
+You can configure for in source tree builds or for a build tree
+that is apart from the source tree.
+
+ - Build in the source tree.
+
+       $ cmake -B .
+
+ - Build in a separate directory (parallel to the curl source tree in this
+   example). The build directory is created for you. This is recommended over
+   building in the source tree to separate source and build artifacts.
+
+       $ cmake -B ../curl-build
+
+For the full list of CMake build configuration variables see
+[the corresponding section](#cmake-build-options).
+
+### Fallback for CMake before version 3.13
+
+CMake before version 3.13 does not support the `-B` option. In that case,
+you must create the build directory yourself, `cd` to it and run `cmake`
+from there:
+
+    $ mkdir ../curl-build
+    $ cd ../curl-build
+    $ cmake ../curl
+
+If you want to build in the source tree, it is enough to do this:
+
+    $ cmake .
+
+### Build system generator selection
+
+You can override CMake's default by using `-G <generator-name>`. For example
+on Windows with multiple build systems if you have MinGW-w64 then you could use
+`-G "MinGW Makefiles"`.
+[List of generator names](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html).
+
+## Using `ccmake`
+
+CMake comes with a curses based interface called `ccmake`. To run `ccmake`
+on a curl use the instructions for the command line cmake, but substitute
+`ccmake` for `cmake`.
+
+This brings up a curses interface with instructions on the bottom of the
+screen. You can press the "c" key to configure the project, and the "g" key to
+generate the project. After the project is generated, you can run make.
+
+## Using `cmake-gui`
+
+CMake also comes with a Qt based GUI called `cmake-gui`. To configure with
+`cmake-gui`, you run `cmake-gui` and follow these steps:
+
+ 1. Fill in the "Where is the source code" combo box with the path to
+    the curl source tree.
+ 2. Fill in the "Where to build the binaries" combo box with the path to
+    the directory for your build tree, ideally this should not be the same
+    as the source tree, but a parallel directory called curl-build or
+    something similar.
+ 3. Once the source and binary directories are specified, press the
+    "Configure" button.
+ 4. Select the native build tool that you want to use.
+ 5. At this point you can change any of the options presented in the GUI.
+    Once you have selected all the options you want, click the "Generate"
+    button.
+
+# Building
+
+Build (you have to specify the build directory).
+
+    $ cmake --build ../curl-build
+
+## Static builds
+
+The CMake build setup is primarily done to work with shared/dynamic third
+party dependencies. When linking with shared libraries, the dependency "chain"
+is handled automatically by the library loader - on all modern systems.
+
+If you instead link with a static library, you need to provide all the
+dependency libraries already at the link command line.
+
+Figuring out all the dependency libraries for a given library is hard, as it
+might involve figuring out the dependencies of the dependencies and they vary
+between platforms and can change between versions.
+
+When using static dependencies, the build scripts mostly assume that you, the
+user, provide all the necessary additional dependency libraries as additional
+arguments in the build.
+
+Building statically is not for the faint of heart.
+
+### Fallback for CMake before version 3.13
+
+CMake before version 3.13 does not support the `--build` option. In that
+case, you have to `cd` to the build directory and use the building tool that
+corresponds to the build files that CMake generated for you. This example
+assumes that CMake generates `Makefile`:
+
+    $ cd ../curl-build
+    $ make
+
+# Testing
+
+(The test suite does not yet work with the cmake build)
+
+# Installing
+
+Install to default location (you have to specify the build directory).
+
+    $ cmake --install ../curl-build
+
+Do not use `--prefix` to change the installation prefix as the output produced
+by the `curl-config` script is determined at CMake configure time. If you want
+to set a custom install prefix for curl, set
+[`CMAKE_INSTALL_PREFIX`](https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html)
+when configuring the CMake build.
+
+### Fallback for CMake before version 3.15
+
+CMake before version 3.15 does not support the `--install` option. In that
+case, you have to `cd` to the build directory and use the building tool that
+corresponds to the build files that CMake generated for you. This example
+assumes that CMake generates `Makefile`:
+
+    $ cd ../curl-build
+    $ make install
+
+# CMake usage
+
+Just as curl can be built and installed using CMake, it can also be used from
+CMake.
+
+## Using `find_package`
+
+To locate libcurl from CMake, one can use the standard
+[`find_package`](https://cmake.org/cmake/help/latest/command/find_package.html)
+command in the typical fashion:
+
+```cmake
+find_package(CURL 8.12.0 REQUIRED)  # FATAL_ERROR if CURL is not found
+```
+
+This invokes the CMake-provided
+[FindCURL](https://cmake.org/cmake/help/latest/module/FindCURL.html) find module,
+which first performs a search using the `find_package`
+[config mode](https://cmake.org/cmake/help/latest/command/find_package.html#config-mode-search-procedure).
+This is supported by the `CURLConfig.cmake` CMake config script which is
+available if the given CURL was built and installed using CMake.
+
+### Detecting CURL features/protocols
+
+Since version 8.12.0, `CURLConfig.cmake` publishes the supported CURL features
+and protocols (see [release notes](https://curl.se/ch/8.12.0.html)). These can
+be specified using the `find_package` keywords `COMPONENTS` and
+`OPTIONAL_COMPONENTS`, with protocols in all caps, e.g. `HTTPS`, `LDAP`, while
+features should be in their original sentence case, e.g. `AsynchDNS`,
+`UnixSockets`. If any of the `COMPONENTS` are missing, then CURL is considered
+as *not* found.
+
+Here is an example of using `COMPONENTS` and `OPTIONAL_COMPONENTS` in
+`find_package` with CURL:
+
+```cmake
+# CURL_FOUND is FALSE if no HTTPS but brotli and zstd can be missing
+find_package(CURL 8.12.0 COMPONENTS HTTPS OPTIONAL_COMPONENTS brotli zstd)
+```
+
+One can also check the defined `CURL_SUPPORTS_<feature-or-protocol>` variables
+if a particular feature/protocol is supported. For example:
+
+```cmake
+# check HTTPS
+if(CURL_SUPPORTS_HTTPS)
+  message(STATUS "CURL supports HTTPS")
+else()
+  message(STATUS "CURL does NOT support HTTPS")
+endif()
+```
+
+### Linking against libcurl
+
+To link a CMake target against libcurl one can use
+[`target_link_libraries`](https://cmake.org/cmake/help/latest/command/target_link_libraries.html)
+as usual:
+
+```cmake
+target_link_libraries(my_target PRIVATE CURL::libcurl)
+```

+## Feature detection variables
+
+By default this CMake build script detects the version of some dependencies
+using `check_symbol_exists`. Those checks do not work in the case that both
+CURL and its dependency are included as sub-projects in a larger build using
+`FetchContent`. To support that case, additional variables may be defined by
+the parent project, ideally in the "extra" find package redirect file:
+<https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package>
+
+Available variables:
+
+- `HAVE_DES_ECB_ENCRYPT`:                   `DES_ecb_encrypt` present in OpenSSL (or fork).
+- `HAVE_GNUTLS_SRP`:                        `gnutls_srp_verifier` present in GnuTLS.
+- `HAVE_LDAP_INIT_FD`:                      `ldap_init_fd` present in LDAP library.

+- `HAVE_OPENSSL_SRP`:                       `SSL_CTX_set_srp_username` present in OpenSSL (or fork).
+- `HAVE_QUICHE_CONN_SET_QLOG_FD`:           `quiche_conn_set_qlog_fd` present in quiche.
+- `HAVE_RUSTLS_SUPPORTED_HPKE`:             `rustls_supported_hpke` present in Rustls (unused if Rustls is detected via `pkg-config`).
+- `HAVE_SSL_SET0_WBIO`:                     `SSL_set0_wbio` present in OpenSSL (or fork).
+- `HAVE_SSL_SET1_ECH_CONFIG_LIST`:          `SSL_set1_ech_config_list` present in OpenSSL (or fork).
+- `HAVE_SSL_SET_QUIC_TLS_CBS`:              `SSL_set_quic_tls_cbs` in OpenSSL.
+- `HAVE_SSL_SET_QUIC_USE_LEGACY_CODEPOINT`: `SSL_set_quic_use_legacy_codepoint` in OpenSSL fork.
+- `HAVE_WOLFSSL_BIO_NEW`:                   `wolfSSL_BIO_new` present in wolfSSL.
+- `HAVE_WOLFSSL_BIO_SET_SHUTDOWN`:          `wolfSSL_BIO_set_shutdown` present in wolfSSL.

+- `HAVE_WOLFSSL_GET_PEER_CERTIFICATE`:      `wolfSSL_get_peer_certificate` present in wolfSSL.
+- `HAVE_WOLFSSL_SET_QUIC_USE_LEGACY_CODEPOINT`:
+                                            `wolfSSL_set_quic_use_legacy_codepoint` present in wolfSSL.
+- `HAVE_WOLFSSL_USEALPN`:                   `wolfSSL_UseALPN` present in wolfSSL.
+
+For each of the above variables, if the variable is *defined* (either to `ON`
+or `OFF`), the symbol detection is skipped. If the variable is *not defined*,
+the feature detection is performed.
+
+Note: These variables are internal and subject to change.

+# Migrating from Visual Studio IDE Project Files
+
+We recommend using CMake to build curl with MSVC.
+
+The project build files reside in project/Windows/VC\* for VS2010, VS2012 and
+VS2013.
+
+These CMake Visual Studio generators require CMake v3.24 or older. You can
+download them from <https://cmake.org/files/v3.24/>.
+
+You can also use `-G "NMake Makefiles"`, which is supported by all CMake
+versions.

+# How to install curl and libcurl
+
+## Installing Binary Packages
+
+Lots of people download binary distributions of curl and libcurl. This
+document does not describe how to install curl or libcurl using such a binary
+package. This document describes how to compile, build and install curl and
+libcurl from [source code](https://curl.se/download.html).
+
+## Building using vcpkg
+
+You can download and install curl and libcurl using
+the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
+
+    git clone https://github.com/Microsoft/vcpkg.git
+    cd vcpkg
+    ./bootstrap-vcpkg.sh
+    ./vcpkg integrate install
+    vcpkg install curl[tool]
+
+The curl port in vcpkg is kept up to date by Microsoft team members and
+community contributors. If the version is out of date, please [create an issue
+or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+## Building from git
+
+If you get your code off a git repository instead of a release tarball, see
+the [GIT-INFO.md](https://github.com/curl/curl/blob/master/GIT-INFO.md) file in
+the root directory for specific instructions on how to proceed.
+
+# Unix
+
+A normal Unix installation is made in three or four steps (after you have
+unpacked the source archive):
+
+    ./configure --with-openssl [--with-gnutls --with-wolfssl]
+    make
+    make test (optional)
+    make install
+
+(Adjust the configure line accordingly to use the TLS library you want.)
+
+You probably need to be root when doing the last command.
+
+Get a full listing of all available configure options by invoking it like:
+
+    ./configure --help
+
+If you want to install curl in a different file hierarchy than `/usr/local`,
+specify that when running configure:
+
+    ./configure --prefix=/path/to/curl/tree
+
+If you have write permission in that directory, you can do 'make install'
+without being root. An example of this would be to make a local install in
+your own home directory:
+
+    ./configure --prefix=$HOME
+    make
+    make install
+
+The configure script always tries to find a working SSL library unless
+explicitly told not to. If you have OpenSSL installed in the default search
+path for your compiler/linker, you do not need to do anything special. If you
+have OpenSSL installed in `/usr/local/ssl`, you can run configure like:
+
+    ./configure --with-openssl
+
+If you have OpenSSL installed somewhere else (for example, `/opt/OpenSSL`) and
+you have pkg-config installed, set the pkg-config path first, like this:
+
+    env PKG_CONFIG_PATH=/opt/OpenSSL/lib/pkgconfig ./configure --with-openssl
+
+Without pkg-config installed, use this:
+
+    ./configure --with-openssl=/opt/OpenSSL
+
+If you insist on forcing a build without SSL support, you can run configure
+like this:
+
+    ./configure --without-ssl
+
+If you have OpenSSL installed, but with the libraries in one place and the
+header files somewhere else, you have to set the `LDFLAGS` and `CPPFLAGS`
+environment variables prior to running configure. Something like this should
+work:
+
+    CPPFLAGS="-I/path/to/ssl/include" LDFLAGS="-L/path/to/ssl/lib" ./configure
+
+If you have shared SSL libs installed in a directory where your runtime
+linker does not find them (which usually causes configure failures), you can
+provide this option to gcc to set a hard-coded path to the runtime linker:
+
+    LDFLAGS=-Wl,-R/usr/local/ssl/lib ./configure --with-openssl
+
+## Static builds
+
+To force a static library compile, disable the shared library creation by
+running configure like:
+
+    ./configure --disable-shared
+
+The configure script is primarily done to work with shared/dynamic third party
+dependencies. When linking with shared libraries, the dependency "chain" is
+handled automatically by the library loader - on all modern systems.
+
+If you instead link with a static library, you need to provide all the
+dependency libraries already at the link command line.
+
+Figuring out all the dependency libraries for a given library is hard, as it
+might involve figuring out the dependencies of the dependencies and they vary
+between platforms and change between versions.
+
+When using static dependencies, the build scripts mostly assume that you, the
+user, provide all the necessary additional dependency libraries as additional
+arguments in the build. With configure, by setting `LIBS` or `LDFLAGS` on the
+command line.
+
+Building statically is not for the faint of heart.
+
+## Debug
+
+If you are a curl developer and use gcc, you might want to enable more debug
+options with the `--enable-debug` option.
+
+curl can be built to use a whole range of libraries to provide various useful
+services, and configure tries to auto-detect a decent default. If you want to
+alter it, you can select how to deal with each individual library.
+
+## Select TLS backend
+
+These options are provided to select the TLS backend to use.
+
+ - AmiSSL: `--with-amissl`
+ - GnuTLS: `--with-gnutls`.
+ - mbedTLS: `--with-mbedtls`
+ - OpenSSL: `--with-openssl` (also for BoringSSL, AWS-LC, LibreSSL, and quictls)
+ - rustls: `--with-rustls`
+ - Schannel: `--with-schannel`
+ - wolfSSL: `--with-wolfssl`
+
+You can build curl with *multiple* TLS backends at your choice, but some TLS
+backends cannot be combined: if you build with an OpenSSL fork (or wolfSSL),
+you cannot add another OpenSSL fork (or wolfSSL) simply because they have
+conflicting identical symbol names.
+
+When you build with multiple TLS backends, you can select the active one at
+runtime when curl starts up.
+
+### Selecting TLS Trust Anchors Defaults
+
+Verifying a server certificate established a chain of trust that needs to
+start somewhere. Those "root" certificates make the set of Trust Anchors.
+
+While the build system tries to find good defaults on the platform you
+use, you may specify these explicitly. The following options are provided:
+
+ - `--with-ca-bundle=FILE`: the file that libcurl loads default root
+ certificates from.
+ - `--with-ca-path=DIRECTORY`: a directory in which root certificates files
+ are found.
+ - `--with-ca-embed=FILE`: a file read *at build time* and added to `libcurl`.
+ - `--with-ca-fallback`: an OpenSSL specific option for delegating default
+ trust anchor selection to what OpenSSL thinks is best, *if* there are
+no other certificates configured by the application.
+ - `--with-apple-sectrust`: use the system "SecTrust" service on Apple
+ operating systems for verification. (Added in 8.17.0)
+
+## MultiSSL and HTTP/3
+
+HTTP/3 needs QUIC and QUIC needs TLS. Building libcurl with HTTP/3 and QUIC
+support is not compatible with the MultiSSL feature: they are mutually
+exclusive. If you need MultiSSL in your build, you cannot have HTTP/3 support
+and vice versa.
+
+libcurl can only use a single TLS library with QUIC and that *same* TLS
+library needs to be used for the other TLS using protocols.
+
+## Configure finding libs in wrong directory
+
+When the configure script checks for third-party libraries, it adds those
+directories to the `LDFLAGS` variable and then tries linking to see if it
+works. When successful, the found directory is kept in the `LDFLAGS` variable
+when the script continues to execute and do more tests and possibly check for
+more libraries.
+
+This can make subsequent checks for libraries wrongly detect another
+installation in a directory that was previously added to `LDFLAGS` by another
+library check.
+
+# Windows
+
+Building for Windows XP is required as a minimum.
+
+You can build curl with:
+
+- Microsoft Visual Studio 2008 v9.0 or later (`_MSC_VER >= 1500`)
+- MinGW-w64 3.0 or later (`__MINGW64_VERSION_MAJOR >= 3`)
+
+## Building Windows DLLs and C runtime (CRT) linkage issues
+
+ As a general rule, building a DLL with static CRT linkage is highly
+ discouraged, and intermixing CRTs in the same app is something to avoid at
+ any cost.
+
+ Reading and comprehending Microsoft Knowledge Base articles KB94248 and
+ KB140584 is a must for any Windows developer. Especially important is full
+ understanding if you are not going to follow the advice given above.
+
+ - [How To Use the C Runtime](https://learn.microsoft.com/troubleshoot/developer/visualstudio/cpp/libraries/use-c-run-time)
+ - [Runtime Library Compiler Options](https://learn.microsoft.com/cpp/build/reference/md-mt-ld-use-run-time-library)
+ - [Potential Errors Passing CRT Objects Across DLL Boundaries](https://learn.microsoft.com/cpp/c-runtime-library/potential-errors-passing-crt-objects-across-dll-boundaries)
+
+If your app is misbehaving in some strange way, or it is suffering from memory
+corruption, before asking for further help, please try first to rebuild every
+single library your app uses as well as your app using the debug
+multi-threaded dynamic C runtime.
+
+ If you get linkage errors read section 5.7 of the FAQ document.
+
+## Cygwin
+
+Almost identical to the Unix installation. Essentially run the configure script in the
+curl source tree root with `sh configure`, then run `make`.
+
+To expand on building with `cygwin` first ensure it is in your path, and there are no
+conflicting tools (*i.e. Chocolatey with sed package*). If so move `cygwin` ahead of any items
+in your path that would conflict with `cygwin` commands, making sure you have the `sh`
+executable in `/bin/` or you see the configure fail toward the end.
+
+Download the setup installer from
+[`cygwin`](https://cygwin.com/) to begin. Additional `cygwin`
+packages are needed for the install. For more on installing packages visit
+[`cygwin setup`](https://cygwin.com/faq/faq.html#faq.setup.cli).
+
+Either run setup-x86_64.exe, then search and select packages individually, or try:
+
+    setup-x86_64.exe -P binutils -P gcc-core -P libpsl-devel -P libtool -P perl -P make
+
+If the latter, matching packages should appear in the install rows (*is fickle though*) after selecting
+the download site i.e. `https://mirrors.kernel.org`. In either case, follow the GUI prompts
+until you reach the "Select Packages" window; then select packages, click next, and finish
+the `cygwin` package installation.
+
+Download the latest version of the `cygwin` packages required (*and suggested*) for a successful install:
+
+<details>
+    <summary>Package List</summary>
+
+```
+ binutil - required
+ gcc-core - required
+ libpsl-devel - required
+ libtool - required
+ perl - required
+ make - required
+ - NOTE - if there is an error regarding make, open the cygwin terminal, and run:
+   ln -s /usr/bin/make /usr/bin/gmake
+```
+
+</details>
+
+Once all the packages have been installed, begin the process of installing curl from the source code:
+
+ <details>
+     <summary>configure_options</summary>
+
+```
+    --with-gnutls
+    --with-mbedtls
+    --with-openssl (also works for OpenSSL forks)
+    --with-rustls
+    --with-wolfssl
+    --without-ssl
+```
+
+ </details>
+
+ 1. `sh configure <configure_options>`
+ 2. `make`
+
+If any error occurs during curl installation, try:
+ - reinstalling the required `cygwin` packages from the list above
+ - temporarily move `cygwin` to the top of your path
+ - install all of the suggested `cygwin` packages
+
+## MS-DOS
+
+You can use either autotools or cmake:
+
+```sh
+./configure \
+  CC=/path/to/djgpp/bin/i586-pc-msdosdjgpp-gcc \
+  AR=/path/to/djgpp/bin/i586-pc-msdosdjgpp-ar \
+  RANLIB=/path/to/djgpp/bin/i586-pc-msdosdjgpp-ranlib \
+  WATT_ROOT=/path/to/djgpp/net/watt \
+  --host=i586-pc-msdosdjgpp \
+  --with-openssl=/path/to/djgpp \
+  --with-zlib=/path/to/djgpp \
+  --without-libpsl \
+  --disable-shared
+```
+
+```sh
+cmake . \
+  -DCMAKE_SYSTEM_NAME=DOS \
+  -DCMAKE_C_COMPILER_TARGET=i586-pc-msdosdjgpp \
+  -DCMAKE_C_COMPILER=/path/to/djgpp/bin/i586-pc-msdosdjgpp-gcc \
+  -DWATT_ROOT=/path/to/djgpp/net/watt \
+  -DOPENSSL_INCLUDE_DIR=/path/to/djgpp/include \
+  -DOPENSSL_SSL_LIBRARY=/path/to/djgpp/lib/libssl.a \
+  -DOPENSSL_CRYPTO_LIBRARY=/path/to/djgpp/lib/libcrypto.a \
+  -DZLIB_INCLUDE_DIR=/path/to/djgpp/include \
+  -DZLIB_LIBRARY=/path/to/djgpp/lib/libz.a \
+  -DCURL_USE_LIBPSL=OFF
+```
+
+Notes:
+
+ - Requires DJGPP 2.04 or upper.
+
+ - Compile Watt-32 (and OpenSSL) with the same version of DJGPP. Otherwise
+   things go wrong because things like FS-extensions and `errno` values have
+   been changed between releases.
+
+## AmigaOS
+
+You can use either autotools or cmake:
+
+```sh
+./configure \
+  CC=/opt/amiga/bin/m68k-amigaos-gcc \
+  AR=/opt/amiga/bin/m68k-amigaos-ar \
+  RANLIB=/opt/amiga/bin/m68k-amigaos-ranlib \
+  --host=m68k-amigaos \
+  --with-amissl \
+  CFLAGS='-O0 -msoft-float -mcrt=clib2' \
+  CPPFLAGS=-I/path/to/AmiSSL/Developer/include \
+  LDFLAGS=-L/path/to/AmiSSL/Developer/lib/AmigaOS3 \
+  LIBS='-lnet -lm -latomic' \
+  --without-libpsl \
+  --disable-shared
+```
+
+```sh
+cmake . \
+  -DAMIGA=1 \
+  -DCMAKE_SYSTEM_NAME=Generic \
+  -DCMAKE_C_COMPILER_TARGET=m68k-unknown-amigaos \
+  -DCMAKE_C_COMPILER=/opt/amiga/bin/m68k-amigaos-gcc \
+  -DCMAKE_C_FLAGS='-O0 -msoft-float -mcrt=clib2' \

+  -DAMISSL_AUTO_LIBRARY=/path/to/AmiSSL/Developer/lib/AmigaOS3/libamisslauto.a \
+  -DCURL_USE_LIBPSL=OFF
+```
+
+## Disabling Specific Protocols in Windows builds
+
+The configure utility, unfortunately, is not available for the Windows
+environment, therefore, you cannot use the various disable-protocol options of
+the configure utility on this platform.
+
+You can use specific defines to disable specific protocols and features. See
+[CURL-DISABLE](https://github.com/curl/curl/blob/master/docs/CURL-DISABLE.md)
+for the full list.
+
+If you want to set any of these defines you have the following options:
+
+ - Modify `lib/config-win32.h`
+ - Modify `lib/curl_setup.h`
+ - Modify the "Preprocessor Definitions" in the libcurl project
+
+Note: The pre-processor settings can be found using the Visual Studio IDE
+under "Project -> Properties -> Configuration Properties -> C/C++ ->
+Preprocessor".
+
+## Using BSD-style lwIP instead of Winsock TCP/IP stack in Windows builds
+
+In order to compile libcurl and curl using BSD-style lwIP TCP/IP stack it is
+necessary to make the definition of the preprocessor symbol `USE_LWIPSOCK`
+visible to libcurl and curl compilation processes. To set this definition you
+have the following alternatives:
+
+ - Modify `lib/config-win32.h`
+ - Modify the "Preprocessor Definitions" in the libcurl project
+
+Note: The pre-processor settings can be found using the Visual Studio IDE
+under "Project -> Properties -> Configuration Properties -> C/C++ ->
+Preprocessor".
+
+Once that libcurl has been built with BSD-style lwIP TCP/IP stack support, in
+order to use it with your program it is mandatory that your program includes
+lwIP header file `<lwip/opt.h>` (or another lwIP header that includes this)
+before including any libcurl header. Your program does not need the
+`USE_LWIPSOCK` preprocessor definition which is for libcurl internals only.
+
+Compilation has been verified with lwIP 1.4.0.
+
+This BSD-style lwIP TCP/IP stack support must be considered experimental given
+that it has been verified that lwIP 1.4.0 still needs some polish, and libcurl
+might yet need some additional adjustment.
+
+## Important static libcurl usage note
+
+When building an application that uses the static libcurl library on Windows,
+you must add `-DCURL_STATICLIB` to your `CFLAGS`. Otherwise the linker looks
+for dynamic import symbols.
+
+## Legacy Windows and SSL
+
+Schannel (from Windows SSPI), is the native SSL library in Windows. However,
+Schannel in Windows <= XP is unable to connect to servers that no longer
+support the legacy handshakes and algorithms used by those versions. If you
+are using curl in one of those earlier versions of Windows you should choose
+another SSL backend such as OpenSSL.
+
+# Android
+
+When building curl for Android you can you CMake or curl's `configure` script.
+
+Before you can build curl for Android, you need to install the Android NDK
+first. This can be done using the SDK Manager that is part of Android Studio.
+Once you have installed the Android NDK, you need to figure out where it has
+been installed and then set up some environment variables before launching
+the build.
+
+Examples to compile for `aarch64` and API level 29:
+
+with CMake, where `ANDROID_NDK_HOME` points into your NDK:
+
+```sh
+cmake . \
+  -DANDROID_ABI=arm64-v8a \
+  -DANDROID_PLATFORM=android-29 \
+  -DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake" \
+  -DCURL_ENABLE_SSL=OFF \
+  -DCURL_USE_LIBPSL=OFF
+```
+
+with `configure`, on macOS:
+
+```sh
+export ANDROID_NDK_HOME=~/Library/Android/sdk/ndk/25.1.8937393 # Point into your NDK.
+# Same tag for Apple Silicon. Other OS values here:
+#   https://developer.android.com/ndk/guides/other_build_systems#overview
+export HOST_TAG=darwin-x86_64
+export TOOLCHAIN=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/$HOST_TAG
+export AR=$TOOLCHAIN/bin/llvm-ar
+export AS=$TOOLCHAIN/bin/llvm-as
+export CC=$TOOLCHAIN/bin/aarch64-linux-android29-clang
+export CXX=$TOOLCHAIN/bin/aarch64-linux-android29-clang++
+export LD=$TOOLCHAIN/bin/ld
+export RANLIB=$TOOLCHAIN/bin/llvm-ranlib
+export STRIP=$TOOLCHAIN/bin/llvm-strip
+```
+
+When building on Linux or targeting other API levels or architectures, you need
+to adjust those variables accordingly. After that you can build curl like this:
+
+    ./configure --host aarch64-linux-android --with-pic --disable-shared
+
+Note that this does not give you SSL/TLS support. If you need SSL/TLS, you
+have to build curl with an SSL/TLS library, e.g. OpenSSL, because it is
+impossible for curl to access Android's native SSL/TLS layer. To build curl
+for Android using OpenSSL, follow the OpenSSL build instructions and then
+install `libssl.a` and `libcrypto.a` to `$TOOLCHAIN/sysroot/usr/lib` and copy
+`include/openssl` to `$TOOLCHAIN/sysroot/usr/include`. Now you can build curl
+for Android using OpenSSL like this:
+
+```sh
+# For OpenSSL/BoringSSL. In general, you need to the SSL/TLS layer's transitive
+# dependencies if you are linking statically.
+LIBS='-lssl -lcrypto -lc++'
+./configure --host aarch64-linux-android --with-pic --disable-shared --with-openssl="$TOOLCHAIN/sysroot/usr"
+```
+
+# IBM i
+
+For IBM i (formerly OS/400), you can use curl in two different ways:
+
+- Natively, running in the **ILE**. The obvious use is being able to call curl
+  from ILE C or RPG applications.
+- You need to build this from source. See `packages/OS400/README` for the ILE
+  specific build instructions.
+- In the **PASE** environment, which runs AIX programs. curl is built as it
+  would be on AIX.
+- IBM provides builds of curl in their Yum repository for PASE software.
+- To build from source, follow the Unix instructions.
+
+There are some additional limitations and quirks with curl on this platform;
+they affect both environments.
+
+## Multi-threading notes
+
+By default, jobs in IBM i does not start with threading enabled. (Exceptions
+include interactive PASE sessions started by `QP2TERM` or SSH.) If you use
+curl in an environment without threading when options like asynchronous DNS
+were enabled, you get messages like:
+
+```
+getaddrinfo() thread failed to start
+```
+
+Do not panic. curl and your program are not broken. You can fix this by:
+
+- Set the environment variable `QIBM_MULTI_THREADED` to `Y` before starting
+  your program. This can be done at whatever scope you feel is appropriate.
+- Alternatively, start the job with the `ALWMLTTHD` parameter set to `*YES`.
+
+# Cross compile
+
+Download and unpack the curl package.
+
+`cd` to the new directory. (e.g. `cd curl-7.12.3`)
+
+Set environment variables to point to the cross-compile toolchain and call
+configure with any options you need. Be sure and specify the `--host` and
+`--build` parameters at configuration time. The following script is an example
+of cross-compiling for the IBM 405GP PowerPC processor using the toolchain on
+Linux.
+
+```sh
+export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
+export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
+export AR=ppc_405-ar
+export AS=ppc_405-as
+export LD=ppc_405-ld
+export RANLIB=ppc_405-ranlib
+export CC=ppc_405-gcc
+export NM=ppc_405-nm
+
+./configure \
+  --target=powerpc-hardhat-linux
+  --host=powerpc-hardhat-linux
+  --build=i586-pc-linux-gnu
+  --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local
+  --exec-prefix=/usr/local
+```
+
+The `--prefix` parameter specifies where curl gets installed. If `configure`
+completes successfully, do `make` and `make install` as usual.
+
+In some cases, you may be able to simplify the above commands to as little as:
+
+    ./configure --host=ARCH-OS
+
+# REDUCING SIZE
+
+There are a number of configure options that can be used to reduce the size of
+libcurl for embedded applications where binary size is an important factor.
+First, be sure to set the `CFLAGS` variable when configuring with any relevant
+compiler optimization flags to reduce the size of the binary. For gcc, this
+would mean at minimum the `-Os` option, and others like the following that
+may be relevant in some environments: `-march=X`, `-mthumb`, `-m32`,
+`-mdynamic-no-pic`, `-flto`, `-fdata-sections`, `-ffunction-sections`,
+`-fno-unwind-tables`, `-fno-asynchronous-unwind-tables`,
+`-fno-record-gcc-switches`, `-fsection-anchors`, `-fno-plt`,
+`-Wl,--gc-sections`, `-Wl,-Bsymbolic`, `-Wl,-s`,
+
+For example, this is how to combine a few of these options:
+
+    ./configure CC=gcc CFLAGS='-Os -ffunction-sections' LDFLAGS='-Wl,--gc-sections'...
+
+Note that newer compilers often produce smaller code than older versions
+due to improved optimization.
+
+Be sure to specify as many `--disable-` and `--without-` flags on the
+configure command-line as you can to disable all the libcurl features that you
+know your application is not going to need. Besides specifying the
+`--disable-PROTOCOL` flags for all the types of URLs your application do not
+use, here are some other flags that can reduce the size of the library by
+disabling support for some features (run `./configure --help` to see them all):
+
+ - `--disable-aws` (cryptographic authentication)
+ - `--disable-basic-auth` (cryptographic authentication)
+ - `--disable-bearer-auth` (cryptographic authentication)
+ - `--disable-digest-auth` (cryptographic authentication)
+ - `--disable-http-auth` (all HTTP authentication)
+ - `--disable-kerberos-auth` (cryptographic authentication)
+ - `--disable-negotiate-auth` (cryptographic authentication)
+ - `--disable-ntlm` (NTLM authentication)
+ - `--disable-alt-svc` (HTTP Alt-Svc)
+ - `--disable-ares` (the C-ARES DNS library)
+ - `--disable-cookies` (HTTP cookies)
+ - `--disable-dateparse` (date parsing for time conditionals)
+ - `--disable-dnsshuffle` (internal server load spreading)
+ - `--disable-doh` (DNS-over-HTTP)
+ - `--disable-form-api` (POST form API)
+ - `--disable-get-easy-options` (lookup easy options at runtime)
+ - `--disable-headers-api` (API to access headers)
+ - `--disable-hsts` (HTTP Strict Transport Security)
+ - `--disable-ipv6` (IPv6)
+ - `--disable-libcurl-option` (--libcurl C code generation support)
+ - `--disable-manual` (--manual built-in documentation)
+ - `--disable-mime` (MIME API)
+ - `--disable-netrc`  (.netrc file)
+ - `--disable-progress-meter` (graphical progress meter in library)
+ - `--disable-proxy` (HTTP and SOCKS proxies)
+ - `--disable-socketpair` (socketpair for asynchronous name resolving)
+ - `--disable-threaded-resolver`  (threaded name resolver)
+ - `--disable-tls-srp` (Secure Remote Password authentication for TLS)
+ - `--disable-unix-sockets` (Unix sockets)
+ - `--disable-verbose` (eliminates debugging strings and error code strings)
+ - `--disable-versioned-symbols` (versioned symbols)
+ - `--enable-symbol-hiding` (eliminates unneeded symbols in the shared library)
+ - `--without-brotli` (Brotli on-the-fly decompression)
+ - `--without-libpsl` (Public Suffix List in cookies)
+ - `--without-nghttp2` (HTTP/2 using nghttp2)
+ - `--without-ngtcp2` (HTTP/2 using ngtcp2)
+ - `--without-zstd` (Zstd on-the-fly decompression)
+ - `--without-libidn2` (internationalized domain names)
+ - `--without-librtmp` (RTMP)
+ - `--without-ssl` (SSL/TLS)
+ - `--without-zlib` (gzip/deflate on-the-fly decompression)
+
+Be sure also to strip debugging symbols from your binaries after compiling
+using 'strip' or an option like `-s`. If space is really tight, you may be able
+to gain a few bytes by removing some unneeded sections of the shared library
+using the -R option to objcopy (e.g. the .comment section).
+
+Using these techniques it is possible to create a basic HTTP-only libcurl
+shared library for i386 Linux platforms that is only 137 KiB in size
+(as of libcurl version 8.13.0, using gcc 14.2.0).
+
+You may find that statically linking libcurl to your application results in a
+lower total size than dynamically linking.
+
+The curl test harness can detect the use of some, but not all, of the
+`--disable` statements suggested above. Use of these can cause tests relying
+on those features to fail. The test harness can be manually forced to skip the
+relevant tests by specifying certain key words on the `runtests.pl` command
+line. Following is a list of appropriate key words for those configure options
+that are not automatically detected:
+
+ - `--disable-cookies`          !cookies
+ - `--disable-dateparse`        !RETRY-AFTER !`CURLOPT_TIMECONDITION` !`CURLINFO_FILETIME` !`If-Modified-Since` !`curl_getdate` !`-z`
+ - `--disable-libcurl-option`   !`--libcurl`
+ - `--disable-verbose`          !verbose\ logs
+
+# Ports
+
+This is a probably incomplete list of known CPU architectures and operating
+systems that curl has been compiled for. If you know a system curl compiles
+and runs on, that is not listed, please let us know.

+# curl internals
+
+The canonical libcurl internals documentation is now in the [everything
+curl](https://everything.curl.dev/internals) book. This file lists supported
+versions of libs and build tools.
+
+## Portability
+
+ We write curl and libcurl to compile with C89 compilers on 32-bit and up
+ machines. Most of libcurl assumes more or less POSIX compliance but that is
+ not a requirement.
+
+ We write libcurl to build and work with lots of third party tools, and we
+ want it to remain functional and buildable with these and later versions
+ (older versions may still work but is not what we work hard to maintain):
+
+## Dependencies
+
+ We aim to support these or later versions.
+
+ - OpenSSL      1.0.2a
+ - LibreSSL     2.9.1
+ - GnuTLS       3.1.10
+ - mbedTLS      3.2.0
+ - zlib         1.2.5.2
+ - libssh2      1.9.0
+ - c-ares       1.6.0
+ - libssh       0.9.0
+ - libidn2      2.0.0
+ - wolfSSL      3.4.6
+ - OpenLDAP     2.0
+ - MIT Kerberos 1.3
+ - nghttp2      1.15.0
+
+## Build tools
+
+ When writing code (mostly for generating stuff included in release tarballs)
+ we use a few "build tools" and we make sure that we remain functional with
+ these versions:
+
+ - GNU Libtool  1.4.2
+ - GNU Autoconf 2.59
+ - GNU Automake 1.7
+ - GNU M4       1.4
+ - perl         5.8
+ - roffit       0.5
+ - cmake        3.7
+
+Library Symbols
+===============
+
+ All symbols used internally in libcurl must use a `Curl_` prefix if they are
+ used in more than a single file. Single-file symbols must be made static.
+ Public ("exported") symbols must use a `curl_` prefix. Public API functions
+ are marked with `CURL_EXTERN` in the public header files so that all others
+ can be hidden on platforms where this is possible.

+# IPFS
+For an overview about IPFS, visit the [IPFS project site](https://ipfs.tech/).
+
+In IPFS there are two protocols. IPFS and IPNS (their workings are explained in detail [here](https://docs.ipfs.tech/concepts/)). The ideal way to access data on the IPFS network is through those protocols. For example to access the Big Buck Bunny video the ideal way to access it is like: `ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi`
+
+## IPFS Gateways
+
+IPFS Gateway acts as a bridge between traditional HTTP clients and IPFS.
+IPFS Gateway specifications of HTTP semantics can be found [here](https://specs.ipfs.tech/http-gateways/).
+
+### Deserialized responses
+
+By default, a gateway acts as a bridge between traditional HTTP clients and IPFS and performs necessary hash verification and deserialization. Through such gateway, users can download files, directories, and other content-addressed data stored with IPFS or IPNS as if they were stored in a traditional web server.
+
+### Verifiable responses
+
+By explicitly requesting [application/vnd.ipld.raw](https://www.iana.org/assignments/media-types/application/vnd.ipld.raw) or [application/vnd.ipld.car](https://www.iana.org/assignments/media-types/application/vnd.ipld.car) responses, by means defined in [Trustless Gateway Specification](https://specs.ipfs.tech/http-gateways/trustless-gateway/), the user is able to fetch raw content-addressed data and [perform hash verification themselves](https://docs.ipfs.tech/reference/http/gateway/#trustless-verifiable-retrieval).
+
+This enables users to use untrusted, public gateways without worrying they might return invalid/malicious bytes.
+
+## IPFS and IPNS protocol handling
+
+There are various ways to access data from the IPFS network. One such way is
+through the concept of public
+"[gateways](https://docs.ipfs.tech/concepts/ipfs-gateway/#overview)". The
+short version is that entities can offer gateway services. An example here
+that is hosted by Protocol Labs (who also makes IPFS) is `dweb.link` and
+`ipfs.io`. Both sites expose gateway functionality. Getting a file through
+`ipfs.io` looks like this:
+`https://ipfs.io/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi`
+
+If you were to be [running your own IPFS
+node](https://docs.ipfs.tech/how-to/command-line-quick-start/) then you, by
+default, also have a [local gateway](https://specs.ipfs.tech/http-gateways/)
+running. In its default configuration the earlier example would then also work
+in this link:
+
+`http://127.0.0.1:8080/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi`
+
+## cURL handling of the IPFS protocols
+
+The IPFS integration in cURL hides this gateway logic for you. Instead of
+providing a full URL to a file on IPFS like this:
+
+```
+curl http://127.0.0.1:8080/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
+```
+
+You can provide it with the IPFS protocol instead:
+```
+curl ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
+```
+
+With the IPFS protocol way of asking a file, cURL still needs to know the
+gateway. curl essentially just rewrites the IPFS based URL to a gateway URL.
+
+### IPFS_GATEWAY environment variable
+
+If the `IPFS_GATEWAY` environment variable is found, its value is used as
+gateway.
+
+### Automatic gateway detection
+
+When you provide no additional details to cURL then it:
+
+1. First looks for the `IPFS_GATEWAY` environment variable and use that if it
+   is set.
+2. Looks for the file: `~/.ipfs/gateway`. If it can find that file then it
+   means that you have a local gateway running and that file contains the URL
+   to your local gateway.
+
+If cURL fails, you are presented with an error message and a link to this page
+to the option most applicable to solving the issue.
+
+### `--ipfs-gateway` argument
+
+You can also provide a `--ipfs-gateway` argument to cURL. This overrules any
+other gateway setting. curl does not fallback to the other options if the
+provided gateway did not work.
+
+## Gateway redirects
+
+A gateway could redirect to another place. For example, `dweb.link` redirects
+[path based](https://docs.ipfs.tech/how-to/address-ipfs-on-web/#path-gateway)
+requests to [subdomain
+based](https://docs.ipfs.tech/how-to/address-ipfs-on-web/#subdomain-gateway)
+ones. A request using:
+
+    curl ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi --ipfs-gateway https://dweb.link
+
+Which would be translated to:
+
+    https://dweb.link/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
+
+redirects to:
+
+    https://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi.ipfs.dweb.link
+
+If you trust this behavior from your gateway of choice then passing the `-L`
+option follows the redirect.
+
+## Error messages and hints
+
+Depending on the arguments, cURL could present the user with an error.
+
+### Gateway file and environment variable
+
+cURL tried to look for the file: `~/.ipfs/gateway` but could not find it. It
+also tried to look for the `IPFS_GATEWAY` environment variable but could not
+find that either. This happens when no extra arguments are passed to cURL and
+letting it try to figure it out [automatically](#automatic-gateway-detection).
+
+Any IPFS implementation that has gateway support should expose its URL in
+`~/.ipfs/gateway`. If you are already running a gateway, make sure it exposes
+the file where cURL expects to find it.
+
+Alternatively you could set the `IPFS_GATEWAY` environment variable or pass
+the `--ipfs-gateway` flag to the cURL command.
+
+### Malformed gateway URL
+
+The command executed evaluates in an invalid URL. This could be anywhere in
+the URL, but a likely point is a wrong gateway URL.
+
+Inspect the URL set via the `IPFS_GATEWAY` environment variable or passed with
+the `--ipfs-gateway` flag. Alternatively opt to go for the
+[automatic](#automatic-gateway-detection) gateway detection.

+
+==============================================================================
+
+1. HTTP
+
+2. TLS
+
+2.1 IMAPS connection fails with Rustls error
+
+ https://github.com/curl/curl/issues/10457
+
+2.2 Access violation sending client cert with Schannel
+
+ When using Schannel to do client certs, curl sets PKCS12_NO_PERSIST_KEY to
+ avoid leaking the private key into the filesystem. Unfortunately that flag
+ instead seems to trigger a crash.
+
+ See https://github.com/curl/curl/issues/17626
+
+2.5 Client cert handling with Issuer DN differs between backends
+
+ When the specified client certificate does not match any of the
+ server-specified DNs, the OpenSSL and GnuTLS backends behave differently.
+ The github discussion may contain a solution.
+
+ See https://github.com/curl/curl/issues/1411
+
+2.7 Client cert (MTLS) issues with Schannel
+
+ See https://github.com/curl/curl/issues/3145
+
+2.11 Schannel TLS 1.2 handshake bug in old Windows versions
+
+ In old versions of Windows such as 7 and 8.1 the Schannel TLS 1.2 handshake
+ implementation likely has a bug that can rarely cause the key exchange to
+ fail, resulting in error SEC_E_BUFFER_TOO_SMALL or SEC_E_MESSAGE_ALTERED.
+
+ https://github.com/curl/curl/issues/5488
+
+2.13 CURLOPT_CERTINFO results in CURLE_OUT_OF_MEMORY with Schannel
+
+ https://github.com/curl/curl/issues/8741
+
+2.14 mbedTLS and CURLE_AGAIN handling
+
+ https://github.com/curl/curl/issues/15801
+
+3. Email protocols
+
+3.1 IMAP SEARCH ALL truncated response
+
+ IMAP "SEARCH ALL" truncates output on large boxes. "A quick search of the
+ code reveals that pingpong.c contains some truncation code, at line 408, when
+ it deems the server response to be too large truncating it to 40 characters"
+ https://curl.se/bug/view.cgi?id=1366
+
+3.2 No disconnect command
+
+ The disconnect commands (LOGOUT and QUIT) may not be sent by IMAP, POP3 and
+ SMTP if a failure occurs during the authentication phase of a connection.
+
+3.4 AUTH PLAIN for SMTP is not working on all servers
+
+ Specifying "--login-options AUTH=PLAIN" on the command line does not seem to
+ work correctly.
+
+ See https://github.com/curl/curl/issues/4080
+
+3.5 APOP authentication fails on POP3
+
+ See https://github.com/curl/curl/issues/10073
+
+3.6 POP3 issue when reading small chunks
+
+ CURL_DBG_SOCK_RMAX=4 ./runtests.pl -v 982
+
+ See https://github.com/curl/curl/issues/12063
+
+4. Command line
+
+4.1 -T /dev/stdin may upload with an incorrect content length
+
+ -T stats the path to figure out its size in bytes to use it as Content-Length
+ if it is a regular file.
+
+ The problem with that is that, on BSDs and some other UNIXes (not Linux),
+ open(path) may not give you a file descriptor with a 0 offset from the start
+ of the file.
+
+ See https://github.com/curl/curl/issues/12177
+
+4.2 -T - always uploads chunked
+
+ When the `<` shell operator is used. curl should realise that stdin is a
+ regular file in this case, and that it can do a non-chunked upload, like it
+ would do if you used -T file.
+
+ See https://github.com/curl/curl/issues/12171
+
+5. Build and portability issues
+
+5.1 OS400 port requires deprecated IBM library
+
+ curl for OS400 requires QADRT to build, which provides ASCII wrappers for
+ libc/POSIX functions in the ILE, but IBM no longer supports or even offers
+ this library to download.
+
+ See https://github.com/curl/curl/issues/5176
+
+5.2 curl-config --libs contains private details
+
+ "curl-config --libs" include details set in LDFLAGS when configure is run
+ that might be needed only for building libcurl. Further, curl-config --cflags
+ suffers from the same effects with CFLAGS/CPPFLAGS.
+
+5.3 LDFLAGS passed too late making libs linked incorrectly
+
+ Compiling latest curl on HP-UX and linking against a custom OpenSSL (which is
+ on the default loader/linker path), fails because the generated Makefile has
+ LDFLAGS passed on after LIBS.
+
+ See https://github.com/curl/curl/issues/14893
+
+5.6 Cygwin: make install installs curl-config.1 twice
+
+ https://github.com/curl/curl/issues/8839
+
+5.12 flaky CI builds
+
+ We run many CI builds for each commit and PR on github, and especially a
+ number of the Windows builds are flaky. This means that we rarely get all CI
+ builds go green and complete without errors. This is unfortunate as it makes
+ us sometimes miss actual build problems and it is surprising to newcomers to
+ the project who (rightfully) do not expect this.
+
+ See https://github.com/curl/curl/issues/6972
+
+5.13 long paths are not fully supported on Windows
+
+ curl on Windows cannot access long paths (paths longer than 260 characters).
+ However, as a workaround, the Windows path prefix \\?\ which disables all
+ path interpretation may work to allow curl to access the path. For example:
+ \\?\c:\longpath.
+
+ See https://github.com/curl/curl/issues/8361
+
+5.15 Unicode on Windows
+
+ Passing in a Unicode filename with -o:
+
+ https://github.com/curl/curl/issues/11461
+
+ Passing in Unicode character with -d:
+
+ https://github.com/curl/curl/issues/12231
+
+ Windows Unicode builds use homedir in current locale
+
+ The Windows Unicode builds of curl use the current locale, but expect Unicode
+ UTF-8 encoded paths for internal use such as open, access and stat. The
+ user's home directory is retrieved via curl_getenv in the current locale and
+ not as UTF-8 encoded Unicode.
+
+ See https://github.com/curl/curl/pull/7252 and
+     https://github.com/curl/curl/pull/7281
+
+ Cannot handle Unicode arguments in non-Unicode builds on Windows
+
+ If a URL or filename cannot be encoded using the user's current codepage then
+ it can only be encoded properly in the Unicode character set. Windows uses
+ UTF-16 encoding for Unicode and stores it in wide characters, however curl
+ and libcurl are not equipped for that at the moment except when built with
+ _UNICODE and UNICODE defined. Except for Cygwin, Windows cannot use UTF-8 as
+ a locale.
+
+  https://curl.se/bug/?i=345
+  https://curl.se/bug/?i=731
+  https://curl.se/bug/?i=3747
+
+ NTLM authentication and Unicode
+
+ NTLM authentication involving Unicode username or password only works
+ properly if built with UNICODE defined together with the Schannel backend.
+ The original problem was mentioned in:
+ https://curl.se/mail/lib-2009-10/0024.html
+ https://curl.se/bug/view.cgi?id=896
+
+ The Schannel version verified to work as mentioned in
+ https://curl.se/mail/lib-2012-07/0073.html
+
+6. Authentication
+
+6.1 Digest auth-int for PUT/POST
+
+ We do not support auth-int for Digest using PUT or POST
+
+6.2 MIT Kerberos for Windows build
+
+ libcurl fails to build with MIT Kerberos for Windows (KfW) due to KfW's
+ library header files exporting symbols/macros that should be kept private to
+ the KfW library. See ticket #5601 at https://krbdev.mit.edu/rt/
+
+6.3 NTLM in system context uses wrong name
+
+ NTLM authentication using SSPI (on Windows) when (lib)curl is running in
+ "system context" makes it use wrong(?) username - at least when compared to
+ what winhttp does. See https://curl.se/bug/view.cgi?id=535
+
+6.5 NTLM does not support password with Unicode 'SECTION SIGN' character
+
+ https://en.wikipedia.org/wiki/Section_sign
+ https://codepoints.net/U+00A7 SECTION SIGN
+ https://github.com/curl/curl/issues/2120
+
+6.6 libcurl can fail to try alternatives with --proxy-any
+
+ When connecting via a proxy using --proxy-any, a failure to establish an
+ authentication causes libcurl to abort trying other options if the failed
+ method has a higher preference than the alternatives. As an example,
+ --proxy-any against a proxy which advertise Negotiate and NTLM, but which
+ fails to set up Kerberos authentication does not proceed to try
+ authentication using NTLM.
+
+ https://github.com/curl/curl/issues/876
+
+6.7 Do not clear digest for single realm
+
+ https://github.com/curl/curl/issues/3267
+
+6.9 SHA-256 digest not supported in Windows SSPI builds
+
+ Windows builds of curl that have SSPI enabled use the native Windows API calls
+ to create authentication strings. The call to InitializeSecurityContext fails
+ with SEC_E_QOP_NOT_SUPPORTED which causes curl to fail with CURLE_AUTH_ERROR.
+
+ Microsoft does not document supported digest algorithms and that SEC_E error
+ code is not a documented error for InitializeSecurityContext (digest).
+
+ https://github.com/curl/curl/issues/6302
+
+6.10 curl never completes Negotiate over HTTP
+
+ Apparently it is not working correctly...?
+
+ See https://github.com/curl/curl/issues/5235
+
+6.11 Negotiate on Windows fails
+
+ When using --negotiate (or NTLM) with curl on Windows, SSL/TLS handshake
+ fails despite having a valid kerberos ticket cached. Works without any issue
+ in Unix/Linux.
+
+ https://github.com/curl/curl/issues/5881
+
+6.13 Negotiate authentication against Hadoop HDFS
+
+ https://github.com/curl/curl/issues/8264
+
+7. FTP
+
+7.4 FTP with ACCT
+
+ When doing an operation over FTP that requires the ACCT command (but not when
+ logging in), the operation fails since libcurl does not detect this and thus
+ fails to issue the correct command: https://curl.se/bug/view.cgi?id=635
+
+7.12 FTPS server compatibility on Windows with Schannel
+
+ FTPS is not widely used with the Schannel TLS backend and so there may be
+ more bugs compared to other TLS backends such as OpenSSL. In the past users
+ have reported hanging and failed connections. It is likely some changes to
+ curl since then fixed the issues. None of the reported issues can be
+ reproduced any longer.
+
+ If you encounter an issue connecting to your server via FTPS with the latest
+ curl and Schannel then please search for open issues or file a new issue.
+
+9. SFTP and SCP
+
+9.1 SFTP does not do CURLOPT_POSTQUOTE correct
+
+ When libcurl sends CURLOPT_POSTQUOTE commands when connected to an SFTP
+ server using the multi interface, the commands are not being sent correctly
+ and instead the connection is "cancelled" (the operation is considered done)
+ prematurely. There is a half-baked (busy-looping) patch provided in the bug
+ report but it cannot be accepted as-is. See
+ https://curl.se/bug/view.cgi?id=748
+
+9.3 Remote recursive folder creation with SFTP
+
+ On this servers, the curl fails to create directories on the remote server
+ even when the CURLOPT_FTP_CREATE_MISSING_DIRS option is set.
+
+ See https://github.com/curl/curl/issues/5204
+
+9.4 libssh blocking and infinite loop problem
+
+ In the SSH_SFTP_INIT state for libssh, the ssh session working mode is set to
+ blocking mode. If the network is suddenly disconnected during sftp
+ transmission, curl is stuck, even if curl is configured with a timeout.
+
+ https://github.com/curl/curl/issues/8632
+
+9.5 Cygwin: "WARNING: UNPROTECTED PRIVATE KEY FILE!"
+
+ Running SCP and SFTP tests on Cygwin makes this warning message appear.
+
+ https://github.com/curl/curl/issues/11244
+
+10. Connection
+
+10.1 --interface with link-scoped IPv6 address
+
+ When you give the `--interface` option telling curl to use a specific
+ interface for its outgoing traffic in combination with an IPv6 address in the
+ URL that uses a link-local scope, curl might pick the wrong address from the
+ named interface and the subsequent transfer fails.
+
+ Example command line:
+
+    curl --interface eth0 'http://[fe80:928d:xxff:fexx:xxxx]/'
+
+ The fact that the given IP address is link-scoped should probably be used as
+ input to somehow make curl make a better choice for this.
+
+ https://github.com/curl/curl/issues/14782
+
+10.2 Does not acknowledge getaddrinfo sorting policy
+
+ Even if a user edits /etc/gai.conf to prefer IPv4, curl still prefers and
+ tries IPv6 addresses first.
+
+ https://github.com/curl/curl/issues/16718
+
+
+10.3 SOCKS-SSPI discards the security context
+
+ After a successful SSPI/GSS-API exchange, the function queries and logs the
+ authenticated username and reports the supported data-protection level, but
+ then immediately deletes the negotiated SSPI security context and frees the
+ credentials before returning. The negotiated context is not stored on the
+ connection and is therefore never used to protect later SOCKS5 traffic.
+
+11. Internals
+
+11.1 gssapi library name + version is missing in curl_version_info()
+
+ The struct needs to be expanded and code added to store this info.
+
+ See https://github.com/curl/curl/issues/13492
+
+11.2 error buffer not set if connection to multiple addresses fails
+
+ If you ask libcurl to resolve a hostname like example.com to IPv6 addresses
+ when you only have IPv4 connectivity. libcurl fails with
+ CURLE_COULDNT_CONNECT, but the error buffer set by CURLOPT_ERRORBUFFER
+ remains empty. Issue: https://github.com/curl/curl/issues/544
+
+11.4 HTTP test server 'connection-monitor' problems
+
+ The 'connection-monitor' feature of the sws HTTP test server does not work
+ properly if some tests are run in unexpected order. Like 1509 and then 1525.
+
+ See https://github.com/curl/curl/issues/868
+
+11.5 Connection information when using TCP Fast Open
+
+ CURLINFO_LOCAL_PORT (and possibly a few other) fails when TCP Fast Open is
+ enabled.
+
+ See https://github.com/curl/curl/issues/1332 and
+ https://github.com/curl/curl/issues/4296
+
+11.6 test cases sometimes timeout
+
+ Occasionally, one of the tests timeouts. Inexplicably.
+
+ See https://github.com/curl/curl/issues/13350
+
+11.7 CURLOPT_CONNECT_TO does not work for HTTPS proxy
+
+ It is unclear if the same option should even cover the proxy connection or if
+ if requires a separate option.
+
+ See https://github.com/curl/curl/issues/14481
+
+11.8 WinIDN test failures
+
+ Test 165 disabled when built with WinIDN.
+
+11.9 setting a disabled option should return CURLE_NOT_BUILT_IN
+
+ When curl has been built with specific features or protocols disabled,
+ setting such options with curl_easy_setopt() should rather return
+ CURLE_NOT_BUILT_IN instead of CURLE_UNKNOWN_OPTION to signal the difference
+ to the application
+
+ See https://github.com/curl/curl/issues/15472
+
+12. LDAP
+
+12.1 OpenLDAP hangs after returning results
+
+ By configuration defaults, OpenLDAP automatically chase referrals on
+ secondary socket descriptors. The OpenLDAP backend is asynchronous and thus
+ should monitor all socket descriptors involved. Currently, these secondary
+ descriptors are not monitored, causing OpenLDAP library to never receive
+ data from them.
+
+ As a temporary workaround, disable referrals chasing by configuration.
+
+ The fix is not easy: proper automatic referrals chasing requires a
+ synchronous bind callback and monitoring an arbitrary number of socket
+ descriptors for a single easy handle (currently limited to 5).
+
+ Generic LDAP is synchronous: OK.
+
+ See https://github.com/curl/curl/issues/622 and
+     https://curl.se/mail/lib-2016-01/0101.html
+
+12.2 LDAP on Windows does authentication wrong?
+
+ https://github.com/curl/curl/issues/3116
+
+12.3 LDAP on Windows does not work
+
+ A simple curl command line getting "ldap://ldap.forumsys.com" returns an
+ error that says "no memory" !
+
+ https://github.com/curl/curl/issues/4261
+
+12.4 LDAPS requests to ActiveDirectory server hang
+
+ https://github.com/curl/curl/issues/9580
+
+13. TCP/IP
+
+13.1 telnet code does not handle partial writes properly
+
+ It probably does not happen too easily because of how slow and infrequent
+ sends are normally performed.
+
+13.2 Trying local ports fails on Windows
+
+ This makes '--local-port [range]' to not work since curl cannot properly
+ detect if a port is already in use, so it tries the first port, uses that and
+ then subsequently fails anyway if that was actually in use.
+
+ https://github.com/curl/curl/issues/8112
+
+15. CMake
+
+15.1 cmake outputs: no version information available
+
+ Something in the SONAME generation seems to be wrong in the cmake build.
+
+ https://github.com/curl/curl/issues/11158
+
+15.6 uses -lpthread instead of Threads::Threads
+
+ See https://github.com/curl/curl/issues/6166
+
+15.7 generated .pc file contains strange entries
+
+ The Libs.private field of the generated .pc file contains -lgcc -lgcc_s -lc
+ -lgcc -lgcc_s
+
+ See https://github.com/curl/curl/issues/6167
+
+15.13 CMake build with MIT Kerberos does not work
+
+ Minimum CMake version was bumped in curl 7.71.0 (#5358) Since CMake 3.2
+ try_compile started respecting the CMAKE_EXE_FLAGS. The code dealing with
+ MIT Kerberos detection sets few variables to potentially weird mix of space,
+ and ;-separated flags. It had to blow up at some point. All the CMake checks
+ that involve compilation are doomed from that point, the configured tree
+ cannot be built.
+
+ https://github.com/curl/curl/issues/6904
+
+16. aws-sigv4
+
+16.2 aws-sigv4 does not handle multipart/form-data correctly
+
+ https://github.com/curl/curl/issues/13351
+
+17. HTTP/2
+
+17.1 HTTP/2 prior knowledge over proxy
+
+ https://github.com/curl/curl/issues/12641
+
+17.2 HTTP/2 frames while in the connection pool kill reuse
+
+ If the server sends HTTP/2 frames (like for example an HTTP/2 PING frame) to
+ curl while the connection is held in curl's connection pool, the socket is
+ found readable when considered for reuse and that makes curl think it is dead
+ and then it is closed and a new connection gets created instead.
+
+ This is *best* fixed by adding monitoring to connections while they are kept
+ in the pool so that pings can be responded to appropriately.
+
+17.3 ENHANCE_YOUR_CALM causes infinite retries
+
+ Infinite retries with 2 parallel requests on one connection receiving GOAWAY
+ with ENHANCE_YOUR_CALM error code.
+
+ See https://github.com/curl/curl/issues/5119
+
+17.4 HTTP/2 + TLS spends a lot of time in recv
+
+ It has been observed that by making the speed limit less accurate we could
+ improve this performance. (by reverting
+ https://github.com/curl/curl/commit/db5c9f4f9e0779b49624752b135281a0717b277b)
+ Can we find a golden middle ground?
+
+ See https://curl.se/mail/lib-2024-05/0026.html and
+ https://github.com/curl/curl/issues/13416
+
+18. HTTP/3
+
+18.1 connection migration does not work
+
+ https://github.com/curl/curl/issues/7695
+
+18.2 quiche: QUIC connection is draining
+
+ The transfer ends with error "QUIC connection is draining".
+
+ https://github.com/curl/curl/issues/12037
+
+18.3 OpenSSL-QUIC problems on google.com
+
+ With some specific Google servers, and seemingly timing dependent, the
+ OpenSSL-QUIC backend seems to not actually send off the HTTP/3 request which
+ makes the QUIC connection just sit idle until killed by the server. curl or
+ OpenSSL bug?
+
+ https://github.com/curl/curl/issues/18336
+
+19. RTSP
+
+19.1 Some methods do not support response bodies
+
+ The RTSP implementation is written to assume that a number of RTSP methods
+ always get responses without bodies, even though there seems to be no
+ indication in the RFC that this is always the case.
+
+ https://github.com/curl/curl/issues/12414

+# Mail etiquette
+
+## About the lists
+
+### Mailing Lists
+
+The mailing lists we have are all listed and described on the [curl
+website](https://curl.se/mail/).
+
+Each mailing list is targeted to a specific set of users and subjects, please
+use the one or the ones that suit you the most.
+
+Each mailing list has hundreds up to thousands of readers, meaning that each
+mail sent is received and read by a large number of people. People from
+various cultures, regions, religions and continents.
+
+### Netiquette
+
+Netiquette is a common term for how to behave on the Internet. Of course, in
+each particular group and subculture there are differences in what is
+acceptable and what is considered good manners.
+
+This document outlines what we in the curl project consider to be good
+etiquette, and primarily this focus on how to behave on and how to use our
+mailing lists.
+
+### Do Not Mail a Single Individual
+
+Many people send one question to one person. One person gets many mails, and
+there is only one person who can give you a reply. The question may be
+something that other people would also like to ask. These other people have no
+way to read the reply, but to ask the one person the question. The one person
+consequently gets overloaded with mail.
+
+If you really want to contact an individual and perhaps pay for his or her
+services, by all means go ahead, but if it is just another curl question, take
+it to a suitable list instead.
+
+### Subscription Required
+
+All curl mailing lists require that you are subscribed to allow a mail to go
+through to all the subscribers.
+
+If you post without being subscribed (or from a different mail address than
+the one you are subscribed with), your mail is simply silently discarded. You
+have to subscribe first, then post.
+
+The reason for this unfortunate and strict subscription policy is of course to
+stop spam from pestering the lists.
+
+### Moderation of new posters
+
+Several of the curl mailing lists automatically make all posts from new
+subscribers be moderated. After you have subscribed and sent your first mail
+to a list, that mail is not let through to the list until a mailing list
+administrator has verified that it is OK and permits it to get posted.
+
+Once a first post has been made that proves the sender is actually talking
+about curl-related subjects, the moderation "flag" is switched off and future
+posts go through without being moderated.
+
+The reason for this moderation policy is that we do suffer from spammers who
+actually subscribe and send spam to our lists.
+
+### Handling trolls and spam
+
+Despite our good intentions and hard work to keep spam off the lists and to
+maintain a friendly and positive atmosphere, there are times when spam and or
+trolls get through.
+
+Troll - "someone who posts inflammatory, extraneous, or off-topic messages in
+an online community"
+
+Spam - "use of electronic messaging systems to send unsolicited bulk messages"
+
+No matter what, we NEVER EVER respond to trolls or spammers on the list. If
+you believe the list admin should do something in particular, contact them
+off-list. The subject is taken care of as much as possible to prevent repeated
+offenses, but responding on the list to such messages never leads to anything
+good and only puts the light even more on the offender: which was the entire
+purpose of it getting sent to the list in the first place.
+
+Do not feed the trolls.
+
+### How to unsubscribe
+
+You can unsubscribe the same way you subscribed in the first place. You go to
+the page for the particular mailing list you are subscribed to and you enter
+your email address and password and press the unsubscribe button.
+
+Also, the instructions to unsubscribe are included in the headers of every
+mail that is sent out to all curl related mailing lists and there is a footer
+in each mail that links to the "admin" page on which you can unsubscribe and
+change other options.
+
+You NEVER EVER email the mailing list requesting someone else to take you off
+the list.
+
+### I posted, now what?
+
+If you are not subscribed with the same email address that you used to send
+the email, your post is silently discarded.
+
+If you posted for the first time to the mailing list, you first need to wait
+for an administrator to allow your email to go through (moderated). This
+normally happens quickly but in case we are asleep, you may have to wait a few
+hours.
+
+Once your email goes through it is sent out to several hundred or even
+thousands of recipients. Your email may cover an area that not that many
+people know about or are interested in. Or possibly the person who knows about
+it is on vacation or under a heavy work load right now. You may have to wait
+for a response and you should not expect to get a response at all. Ideally,
+you get an answer within a couple of days.
+
+You do yourself and all of us a service when you include as many details as
+possible already in your first email. Mention your operating system and
+environment. Tell us which curl version you are using and tell us what you
+did, what happened and what you expected would happen. Preferably, show us
+what you did with details enough to allow others to help point out the problem
+or repeat the steps in their locations.
+
+Failing to include details only delays responses and make people respond and
+ask for more details and you have to send follow-up emails that include them.
+
+Expect the responses to primarily help YOU debug the issue, or ask YOU
+questions that can lead you or others towards a solution or explanation to
+whatever you experience.
+
+If you are a repeat offender to the guidelines outlined in this document,
+chances are that people ignore you and your chances to get responses in the
+future greatly diminish.
+
+### Your emails are public
+
+Your email, its contents and all its headers and the details in those headers
+are received by every subscriber of the mailing list that you send your email
+to.
+
+Your email as sent to a curl mailing list ends up in mail archives, on the
+curl website and elsewhere, for others to see and read. Today and in the
+future. In addition to the archives, the mail is sent out to thousands of
+individuals. There is no way to undo a sent email.
+
+When sending emails to a curl mailing list, do not include sensitive
+information such as usernames and passwords; use fake ones, temporary ones or
+just remove them completely from the mail. Note that this includes base64
+encoded HTTP Basic auth headers.
+
+This public nature of the curl mailing lists makes automatically inserted mail
+footers about mails being "private" or "only meant for the recipient" or
+similar even more silly than usual. Because they are absolutely not private
+when sent to a public mailing list.
+
+## Sending mail
+
+### Reply or New Mail
+
+Please do not reply to an existing message as a short-cut to post a message to
+the lists.
+
+Many mail programs and web archivers use information within mails to keep them
+together as "threads", as collections of posts that discuss a certain subject.
+If you do not intend to reply on the same or similar subject, do not just hit
+reply on an existing mail and change the subject, create a new mail.
+
+### Reply to the List
+
+When replying to a message from the list, make sure that you do "group reply"
+or "reply to all", and not just reply to the author of the single mail you
+reply to.
+
+We are actively discouraging replying to the single person by setting the
+correct field in outgoing mails back asking for replies to get sent to the
+mailing list address, making it harder for people to reply to the author only
+by mistake.
+
+### Use a Sensible Subject
+
+Please use a subject of the mail that makes sense and that is related to the
+contents of your mail. It makes it a lot easier to find your mail afterwards
+and it makes it easier to track mail threads and topics.
+
+### Do Not Top-Post
+
+If you reply to a message, do not use top-posting. Top-posting is when you
+write the new text at the top of a mail and you insert the previous quoted
+mail conversation below. It forces users to read the mail in a backwards order
+to properly understand it.
+
+This is why top posting is so bad (in top posting order):
+
+    A: Because it messes up the order in which people normally read text.
+    Q: Why is top-posting such a bad thing?
+    A: Top-posting.
+    Q: What is the most annoying thing in email?
+
+Apart from the screwed up read order (especially when mixed together in a
+thread when someone responds using the mandated bottom-posting style), it also
+makes it impossible to quote only parts of the original mail.
+
+When you reply to a mail. You let the mail client insert the previous mail
+quoted. Then you put the cursor on the first line of the mail and you move
+down through the mail, deleting all parts of the quotes that do not add
+context for your comments. When you want to add a comment you do so, inline,
+right after the quotes that relate to your comment. Then you continue
+downwards again.
+
+When most of the quotes have been removed and you have added your own words,
+you are done.
+
+### HTML is not for mails
+
+Please switch off those HTML encoded messages. You can mail all those funny
+mails to your friends. We speak plain text mails.
+
+### Quoting
+
+Quote as little as possible. Just enough to provide the context you cannot
+eave out. A lengthy description can be found
+[here](https://www.netmeister.org/news/learn2quote.html).
+
+### Digest
+
+We allow subscribers to subscribe to the "digest" version of the mailing
+lists. A digest is a collection of mails lumped together in one single mail.
+
+Should you decide to reply to a mail sent out as a digest, there are two
+things you MUST consider if you really, really cannot subscribe normally
+instead:
+
+Cut off all mails and chatter that is not related to the mail you want to
+reply to.
+
+Change the subject name to something sensible and related to the subject,
+preferably even the actual subject of the single mail you wanted to reply to
+
+### Please Tell Us How You Solved The Problem
+
+Many people mail questions to the list, people spend some of their time and
+make an effort in providing good answers to these questions.
+
+If you are the one who asks, please consider responding once more in case one
+of the hints was what solved your problems. The guys who write answers feel
+good to know that they provided a good answer and that you fixed the problem.
+Far too often, the person who asked the question is never heard from again,
+and we never get to know if they are gone because the problem was solved or
+perhaps because the problem was unsolvable.
+
+Getting the solution posted also helps other users that experience the same
+problem(s). They get to see (possibly in the web archives) that the suggested
+fixes actually have helped at least one person.

+curl release procedure - how to do a release
+============================================
+
+in the source code repo
+-----------------------
+
+- edit `RELEASE-NOTES` to be accurate
+
+- update `docs/THANKS`
+
+- update the "past releases" section in `docs/VERSIONS.md`
+
+- make sure all relevant changes are committed on the master branch
+
+- tag the git repo in this style: `git tag -a curl-7_34_0`. -a annotates the
+  tag and we use underscores instead of dots in the version number. Make sure
+  the tag is GPG signed (using -s).
+
+- run `./scripts/dmaketgz 7.34.0` to build the release tarballs.
+
+- push the git commits and the new tag
+
+- GPG sign the 4 tarballs as `maketgz` suggests
+
+- upload the 8 resulting files to the primary download directory
+
+in the curl-www repo
+--------------------
+
+- edit `Makefile` (version number and date),
+
+- edit `_changes.html` (insert changes+bugfixes from RELEASE-NOTES)
+
+- commit all local changes
+
+- tag the repo with the same name as used for the source repo.
+
+- make sure all relevant changes are committed and pushed on the master branch
+
+  (the website then updates its contents automatically)
+
+on GitHub
+---------
+
+- edit the newly made release tag so that it is listed as the latest release
+
+inform
+------
+
+- send an email to curl-users, curl-announce and curl-library. Insert the
+  RELEASE-NOTES into the mail.
+
+- if there are any advisories associated with the release, send each markdown
+  file to the above lists as well as to `oss-security@lists.openwall.com`
+  (unless the problem is unique to the non-open operating systems)
+
+celebrate
+---------
+
+- suitable beverage intake is encouraged for the festivities
+
+curl release scheduling
+=======================
+
+Release Cycle
+-------------
+
+We normally do releases every 8 weeks on Wednesdays. If important problems
+arise, we can insert releases outside the schedule or we can move the release
+date.
+
+Each 8 week (56 days) release cycle is divided into three distinct periods:
+
+- During the first 10 calendar days after a release, we are in "cool down". We
+  do not merge features but only bug-fixes. If a regression is reported, we
+  might do a follow-up patch release.
+
+- During the following 3 weeks (21 days) there is a feature window: we allow
+  new features and changes to curl and libcurl. If we accept any such changes,
+  we bump the minor number used for the next release.
+
+- During the next 25 days we are in feature freeze. We do not merge any
+  features or changes, and we only focus on fixing bugs and polishing things
+  to make the pending release a solid one.
+
+If a future release date happens to end up on a "bad date", like in the middle
+of common public holidays or when the lead release manager is unavailable, the
+release date can be moved forwards or backwards a full week. This is then
+advertised well in advance.
+
+Release Candidates
+------------------
+
+We ship release candidate tarballs on three occasions in preparation for the
+pending release:
+
+- Release candidate one (**rc1**) ships the same Saturday the feature freeze
+  starts. Twenty-five days before the release. Tagged like `rc-7_34_0-1`.
+
+- Release candidate two (**rc2**) ships nine days later, sixteen days before
+  the release. On a Monday. Tagged like `rc-7_34_0-2`.
+
+- Release candidate tree (**rc3**) ships nine days later, seven days before
+  the release. On a Wednesday. Tagged like `rc-7_34_0-3`.
+
+Release candidate tarballs are ephemeral and each such tarball is only kept
+around for a few weeks. They are provided on their dedicated webpage at:
+https://curl.se/rc/
+
+The git tags for release candidate are temporary and remain set only for a
+limited period of time.
+
+**Do not use release candidates in production**. They are work in progress.
+Use them for testing and verification only. Use actual releases in production.
+
+Critical problems
+-----------------
+
+We can break the release cycle and do a patch release at any point if a
+critical enough problem is reported. There is no exact definition of how to
+assess such criticality, but if an issue is highly disturbing or has a
+security impact on a large enough share of the user population it might
+qualify.
+
+If you think an issue qualifies, bring it to the curl-library mailing list and
+push for it.
+
+Coming dates
+------------
+
+Based on the description above, here are some planned future release dates:
+
+- September 10, 2025
+- November 5, 2025
+- January 7, 2026
+- March 4, 2026
+- April 29, 2026

+# Rustls
+
+[Rustls is a TLS backend written in Rust](https://docs.rs/rustls/). curl can
+be built to use it as an alternative to OpenSSL or other TLS backends. We use
+the [rustls-ffi C bindings](https://github.com/rustls/rustls-ffi). This
+version of curl is compatible with `rustls-ffi` v0.15.x.
+
+## Getting rustls-ffi
+
+To build `curl` with `rustls` support you need to have `rustls-ffi` available first.
+There are three options for this:
+
+1. Install it from your package manager, if available.
+2. Download pre-built binaries.
+3. Build it from source.
+
+### Installing rustls-ffi from a package manager
+
+See the [rustls-ffi README] for packaging status. Availability and details for installation
+differ between distributions.
+
+Once installed, build `curl` using `--with-rustls`.
+
+    % git clone https://github.com/curl/curl
+    % cd curl
+    % autoreconf -fi
+    % ./configure --with-rustls
+    % make
+
+[rustls-ffi README]: https://github.com/rustls/rustls-ffi?tab=readme-ov-file
+
+### Downloading pre-built rustls-ffi binaries
+
+Pre-built binaries are available on the [releases page] on GitHub for releases since 0.15.0.
+Download the appropriate archive for your platform and extract it to a directory of your choice
+(e.g. `${HOME}/rustls-ffi-built`).
+
+Once downloaded, build `curl` using `--with-rustls` and the path to the extracted binaries.
+
+    % git clone https://github.com/curl/curl
+    % cd curl
+    % autoreconf -fi
+    % ./configure --with-rustls=${HOME}/rustls-ffi-built
+    % make
+
+[releases page]: https://github.com/rustls/rustls-ffi/releases
+
+### Building rustls-ffi from source
+
+Building `rustls-ffi` from source requires both a rust compiler, and the [cargo-c] cargo plugin.
+
+To install a Rust compiler, use [rustup] or your package manager to install
+the **1.73+** or newer toolchain.
+
+To install `cargo-c`, use your [package manager][cargo-c pkg], download
+[a pre-built archive][cargo-c prebuilt], or build it from source with `cargo install cargo-c`.
+
+Next, check out, build, and install the appropriate version of `rustls-ffi` using `cargo`:
+
+    % git clone https://github.com/rustls/rustls-ffi -b v0.15.0
+    % cd rustls-ffi
+    % cargo capi install --release --prefix=${HOME}/rustls-ffi-built
+
+Now configure and build `curl` using `--with-rustls`:
+
+    % git clone https://github.com/curl/curl
+    % cd curl
+    % autoreconf -fi
+    % ./configure --with-rustls=${HOME}/rustls-ffi-built
+    % make
+
+See the [rustls-ffi README][cryptography provider] for more information on cryptography providers and
+their build/platform requirements.

+
+# Anatomy of a curl security advisory
+
+As described in the [Security Process](https://curl.se/dev/secprocess.html)
+document, when a security vulnerability has been reported to the project and
+confirmed, we author an advisory document for the issue. It should ideally
+be written in cooperation with the reporter to make sure all the angles and
+details of the problem are gathered and described correctly and succinctly.
+
+## New document
+
+A security advisory for curl is created in the `docs/` folder in the
+[curl-www](https://github.com/curl/curl-www) repository. It should be named
+`$CVEID.md` where `$CVEID` is the full CVE Id that has been registered for the
+flaw. Like `CVE-2016-0755`. The `.md` extension of course means that the
+document is written using markdown.
+
+The standard way to go about this is to first write the `VULNERABILITY`
+section for the document, so that there is description of the flaw available,
+then paste this description into the CVE Id request.
+
+### `vuln.pm`
+
+The new issue should be entered at the top of the list in the file `vuln.pm`
+in the same directory. It holds a large array with all published curl
+vulnerabilities. All fields should be filled in accordingly, separated by a
+pipe character (`|`).
+
+The eleven fields for each CVE in `vuln.pm` are, in order:
+
+ HTML page name, first vulnerable version, last vulnerable version, name of
+ the issue, CVE Id, announce date (`YYYYMMDD`), report to the project date
+ (`YYYYMMDD`), CWE, awarded reward amount (USD), area (single word), C-issue
+ (`-` if not a C issue at all, `OVERFLOW` , `OVERREAD`, `DOUBLE_FREE`,
+ `USE_AFTER_FREE`, `NULL_MISTAKE`, `UNINIT`)
+
+### `Makefile`
+
+The new CVE webpage filename needs to be added in the `Makefile`'s `CVELIST`
+macro.
+
+When the markdown is in place and the `Makefile` and `vuln.pm` are updated,
+all other files and metadata for all curl advisories and versions get
+generated automatically using those files.
+
+## Document format
+
+The easy way is to start with a recent previously published advisory and just
+blank out old texts and save it using a new name. Save the subtitles and
+general layout.
+
+Some details and metadata are extracted from this document so it is important
+to stick to the existing format.
+
+The first list must be the title of the issue.
+
+### VULNERABILITY
+
+The first subtitle should be `VULNERABILITY`. That should then include a
+through and detailed description of the flaw. Including how it can be
+triggered and maybe something about what might happen if triggered or
+exploited.
+
+### INFO
+
+The next section is `INFO` which adds meta data information about the flaw. It
+specifically mentions the official CVE Id for the issue and it must list the
+CWE Id, starting on its own line. We write CWE identifiers in advisories with
+the full (official) explanation on the right side of a colon. Like this:
+
+`CWE-305: Authentication Bypass by Primary Weakness`
+
+### AFFECTED VERSIONS
+
+The third section first lists what versions that are affected, then adds
+clarity by stressing what versions that are *not* affected. A third line adds
+information about which specific git commit that introduced the vulnerability.
+
+The `Introduced-in` commit should be a full URL that displays the commit, but
+should work as a stand-alone commit hash if everything up to the last slash is
+cut out.
+
+An example using the correct syntax:
+
+~~~
+- Affected versions: curl 7.16.1 to and including 7.88.1
+- Not affected versions: curl < 7.16.1 and curl >= 8.0.0
+- Introduced-in: https://github.com/curl/curl/commit/2147284cad
+~~~
+
+### THE SOLUTION
+
+This section describes and discusses the fix. The only mandatory information
+here is the link to the git commit that fixes the problem.
+
+The `Fixed-in` value should be a full URL that displays the commit, but should
+work as a stand-alone commit hash if everything up to the last slash is cut
+out.
+
+Example:
+
+`- Fixed-in: https://github.com/curl/curl/commit/af369db4d3833272b8ed`
+
+### RECOMMENDATIONS
+
+This section lists the recommended actions for the users in a top to bottom
+priority order and should ideally contain three items but no less than two.
+
+The top two are almost always `upgrade curl to version XXX` and `apply the
+patch to your local version`.
+
+### TIMELINE
+
+Detail when this report was received in the project. When package distributors
+were notified (via the distros mailing list or similar)
+
+When the advisory and fixed version are released.
+
+### CREDITS
+
+Mention the reporter and patch author at least, then everyone else involved
+you think deserves a mention.
+
+If you want to mention more than one name, separate the names with comma
+(`,`).
+
+~~~
+- Reported-by: Full Name
+- Patched-by: Full Name

+
+A sponsor is someone who donates money or resources to the curl project for no
+specific service in return.
+
+curl accepts donations via [GitHub sponsors](https://github.com/sponsors/curl)
+and [Open Collective](https://opencollective.com/curl).
+
+An even better way to contribute to the project might be to pay an engineer or
+two to spend work hours on curl related tasks.
+
+We promise to use donated funds for things and activities that we believe are
+beneficial for the project and its development. That includes but is not
+limited to bug-bounties, developer conferences, infrastructure, development,
+services and hardware.
+
+Recurring donations above a certain amount of money puts the sponsor at a
+named sponsor level: **Silver**, **Gold**, **Platinum** or **Top**.
+
+Sponsors on a named level can provide their logo image and preferred URL and
+get recognition on the curl website's [sponsor
+page](https://curl.se/sponsors.html), assuming they meet the project's
+standards and requirements.
+
+- **Silver Sponsor** at least 100 USD/month
+- **Gold Sponsor** at least 500 USD/month
+- **Platinum Sponsor** at least 1000 USD/month
+- **Top Sponsor** outstanding extra valuable help
+
+## Sponsor requirements
+
+A named level sponsor is entitled a logo and link on the curl website assuming
+the company, brand and link are not deemed unsuitable. The curl team reserves
+the right to make that decision at its own discretion.
+
+Sponsors may be denied a website presence for example if involved with drugs,
+gambling, pornography, social media manipulation etc.
+
+## Past Sponsors
+
+Sponsors that stop paying are considered *Past Sponsors* and are not displayed
+on the sponsor page anymore. We thank you for your contributions.
+
+## Donations
+
+Please note that sponsorship and donations are exactly that: donations to the
+curl project. They are used to help and further the project as the project
+leadership deems best. No goods or services are expected or promised in
+return. Requests for refunds for such purposes are rejected.

+
+# SSL problems
+
+  First, let's establish that we often refer to TLS and SSL interchangeably as
+  SSL here. The current protocol is called TLS, it was called SSL a long time
+  ago.
+
+  There are several known reasons why a connection that involves SSL might
+  fail. This is a document that attempts to detail the most common ones and
+  how to mitigate them.
+
+## CA certs
+
+  CA certs are used to digitally verify the server's certificate. You need a
+  "ca bundle" for this. See lots of more details on this in the `SSLCERTS`
+  document.
+
+## CA bundle missing intermediate certificates
+
+  When using said CA bundle to verify a server cert, you may experience
+  problems if your CA store does not contain the certificates for the
+  intermediates if the server does not provide them.
+
+  The TLS protocol mandates that the intermediate certificates are sent in the
+  handshake, but as browsers have ways to survive or work around such
+  omissions, missing intermediates in TLS handshakes still happen that browser
+  users do not notice.
+
+  Browsers work around this problem in two ways: they cache intermediate
+  certificates from previous transfers and some implement the TLS "AIA"
+  extension that lets the client explicitly download such certificates on
+  demand.
+
+## Protocol version
+
+  Some broken servers fail to support the protocol negotiation properly that
+  SSL servers are supposed to handle. This may cause the connection to fail
+  completely. Sometimes you may need to explicitly select an SSL version to
+  use when connecting to make the connection succeed.
+
+  An additional complication can be that modern SSL libraries sometimes are
+  built with support for older SSL and TLS versions disabled.
+
+  All versions of SSL and the TLS versions before 1.2 are considered insecure
+  and should be avoided. Use TLS 1.2 or later.
+
+## Ciphers
+
+  Clients give servers a list of ciphers to select from. If the list does not
+  include any ciphers the server wants/can use, the connection handshake
+  fails.
+
+  curl has recently disabled the user of a whole bunch of seriously insecure
+  ciphers from its default set (slightly depending on SSL backend in use).
+
+  You may have to explicitly provide an alternative list of ciphers for curl
+  to use to allow the server to use a weak cipher for you.
+
+  Note that these weak ciphers are identified as flawed. For example, this
+  includes symmetric ciphers with less than 128 bit keys and RC4.
+
+  Schannel in Windows XP is not able to connect to servers that no longer
+  support the legacy handshakes and algorithms used by those versions, so we
+  advise against building curl to use Schannel on really old Windows versions.
+
+  Reference: [Prohibiting RC4 Cipher
+  Suites](https://datatracker.ietf.org/doc/html/draft-popov-tls-prohibiting-rc4-01)
+
+## Allow BEAST
+
+  BEAST is the name of a TLS 1.0 attack that surfaced 2011. When adding means
+  to mitigate this attack, it turned out that some broken servers out there in
+  the wild did not work properly with the BEAST mitigation in place.
+
+  To make such broken servers work, the --ssl-allow-beast option was
+  introduced. Exactly as it sounds, it re-introduces the BEAST vulnerability
+  but on the other hand it allows curl to connect to that kind of strange
+  servers.
+
+## Disabling certificate revocation checks
+
+  Some SSL backends may do certificate revocation checks (CRL, OCSP, etc)
+  depending on the OS or build configuration. The --ssl-no-revoke option was
+  introduced in 7.44.0 to disable revocation checking but currently is only
+  supported for Schannel (the native Windows SSL library), with an exception
+  in the case of Windows' Untrusted Publishers block list which it seems cannot
+  be bypassed. This option may have broader support to accommodate other SSL
+  backends in the future.

+# TLS Certificate Verification
+
+## Native vs file based
+
+If curl was built with Schannel support, then curl uses the Windows native CA
+store for verification. On Apple operating systems, it is possible to use Apple's
+"SecTrust" services for certain TLS backends, details below.
+All other TLS libraries use a file based CA store by
+default.
+
+## Verification
+
+Every trusted server certificate is digitally signed by a Certificate
+Authority, a CA.
+
+In your local CA store you have a collection of certificates from *trusted*
+certificate authorities that TLS clients like curl use to verify servers.
+
+curl does certificate verification by default. This is done by verifying the
+signature and making sure the certificate was crafted for the server name
+provided in the URL.
+
+If you communicate with HTTPS, FTPS or other TLS-using servers using
+certificates signed by a CA whose certificate is present in the store, you can
+be sure that the remote server really is the one it claims to be.
+
+If the remote server uses a self-signed certificate, if you do not install a
+CA cert store, if the server uses a certificate signed by a CA that is not
+included in the store you use or if the remote host is an impostor
+impersonating your favorite site, the certificate check fails and reports an
+error.
+
+If you think it wrongly failed the verification, consider one of the following
+sections.
+
+### Skip verification
+
+Tell curl to *not* verify the peer with `-k`/`--insecure`.
+
+We **strongly** recommend this is avoided and that even if you end up doing
+this for experimentation or development, **never** skip verification in
+production.
+
+### Use a custom CA store
+
+Get a CA certificate that can verify the remote server and use the proper
+option to point out this CA cert for verification when connecting - for this
+specific transfer only.
+
+With the curl command line tool: `--cacert [file]`
+
+If you use the curl command line tool without a native CA store, then you can
+specify your own CA cert file by setting the environment variable
+`CURL_CA_BUNDLE` to the path of your choice. `SSL_CERT_FILE` and `SSL_CERT_DIR`
+are also supported.
+
+If you are using the curl command line tool on Windows, curl searches for a CA
+cert file named `curl-ca-bundle.crt` in these directories and in this order:
+  1. application's directory
+  2. current working directory
+  3. Windows System directory (e.g. C:\Windows\System32)
+  4. Windows Directory (e.g. C:\Windows)
+  5. all directories along %PATH%
+
+curl 8.11.0 added a build-time option to disable this search behavior, and
+another option to restrict search to the application's directory.
+
+### Use the native store
+
+In several environments, in particular on Microsoft and Apple operating
+systems, you can ask curl to use the system's native CA store when verifying
+the certificate. Depending on how curl was built, this may already be the
+default.
+
+With the curl command line tool: `--ca-native`.
+
+### Modify the CA store
+
+Add the CA cert for your server to the existing default CA certificate store.
+
+Usually you can figure out the path to the local CA store by looking at the
+verbose output that `curl -v` shows when you connect to an HTTPS site.
+
+### Change curl's default CA store
+
+The default CA certificate store curl uses is set at build time. When you
+build curl you can point out your preferred path.
+
+### Extract CA cert from a server
+
+    curl -w %{certs} https://example.com > cacert.pem
+
+The certificate has `BEGIN CERTIFICATE` and `END CERTIFICATE` markers.
+
+### Get the Mozilla CA store
+
+Download a version of the Firefox CA store converted to PEM format on the [CA
+Extract](https://curl.se/docs/caextract.html) page. It always features the
+latest Firefox bundle.
+
+## Native CA store
+
+### Windows + Schannel
+
+If curl was built with Schannel, then curl uses the certificates that are
+built into the OS. These are the same certificates that appear in the
+Internet Options control panel (under Windows).
+Any custom security rules for certificates are honored.
+
+Schannel runs CRL checks on certificates unless peer verification is disabled.
+
+### Apple + OpenSSL/GnuTLS
+
+When curl is built with Apple SecTrust enabled and uses an OpenSSL compatible
+TLS backend or GnuTLS, the default verification is handled by that Apple
+service. As in:
+
+    curl https://example.com
+
+You may still provide your own certificates on the command line, such as:
+
+    curl --cacert mycerts.pem https://example.com
+
+In this situation, Apple SecTrust is **not** used and verification is done
+**only** with the trust anchors found in `mycerts.pem`. If you want **both**
+Apple SecTrust and your own file to be considered, use:
+
+    curl --ca-native --cacert mycerts.pem https://example.com
+
+
+#### Other Combinations
+
+How well the use of native CA stores work in all other combinations depends
+on the TLS backend and the OS. Many TLS backends offer functionality to access
+the native CA on a range of operating systems. Some provide this only on specific
+configurations.
+
+Specific support in curl exists for Windows and OpenSSL compatible TLS backends.
+It tries to load the certificates from the Windows "CA" and "ROOT" stores for
+transfers requesting the native CA. Due to Window's delayed population of those
+stores, this might not always find all certificates.
+
+## HTTPS proxy
+
+curl can do HTTPS to the proxy separately from the connection to the server.
+This TLS connection is handled and verified separately from the server
+connection so instead of `--insecure` and `--cacert` to control the
+certificate verification, you use `--proxy-insecure` and `--proxy-cacert`.
+With these options, you make sure that the TLS connection and the trust of the
+proxy can be kept totally separate from the TLS connection to the server.

+# The Art Of Scripting HTTP Requests Using curl
+
+## Background
+
+ This document assumes that you are familiar with HTML and general networking.
+
+ The increasing amount of applications moving to the web has made "HTTP
+ Scripting" more frequently requested and wanted. To be able to automatically
+ extract information from the web, to fake users, to post or upload data to
+ web servers are all important tasks today.
+
+ curl is a command line tool for doing all sorts of URL manipulations and
+ transfers, but this particular document focuses on how to use it when doing
+ HTTP requests for fun and profit. This documents assumes that you know how to
+ invoke `curl --help` or `curl --manual` to get basic information about it.
+
+ curl is not written to do everything for you. It makes the requests, it gets
+ the data, it sends data and it retrieves the information. You probably need
+ to glue everything together using some kind of script language or repeated
+ manual invokes.
+
+## The HTTP Protocol
+
+ HTTP is the protocol used to fetch data from web servers. It is a simple
+ protocol that is built upon TCP/IP. The protocol also allows information to
+ get sent to the server from the client using a few different methods, as is
+ shown here.
+
+ HTTP is plain ASCII text lines being sent by the client to a server to
+ request a particular action, and then the server replies a few text lines
+ before the actual requested content is sent to the client.
+
+ The client, curl, sends an HTTP request. The request contains a method (like
+ GET, POST, HEAD etc), a number of request headers and sometimes a request
+ body. The HTTP server responds with a status line (indicating if things went
+ well), response headers and most often also a response body. The "body" part
+ is the plain data you requested, like the actual HTML or the image etc.
+
+## See the Protocol
+
+ Using curl's option [`--verbose`](https://curl.se/docs/manpage.html#-v) (`-v`
+ as a short option) displays what kind of commands curl sends to the server,
+ as well as a few other informational texts.
+
+ `--verbose` is the single most useful option when it comes to debug or even
+ understand the curl<->server interaction.
+
+ Sometimes even `--verbose` is not enough. Then
+ [`--trace`](https://curl.se/docs/manpage.html#-trace) and
+ [`--trace-ascii`](https://curl.se/docs/manpage.html#--trace-ascii)
+ offer even more details as they show **everything** curl sends and
+ receives. Use it like this:
+
+    curl --trace-ascii debugdump.txt http://www.example.com/
+
+## See the Timing
+
+ Many times you may wonder what exactly is taking all the time, or you just
+ want to know the amount of milliseconds between two points in a transfer. For
+ those, and other similar situations, the
+ [`--trace-time`](https://curl.se/docs/manpage.html#--trace-time) option is
+ what you need. It prepends the time to each trace output line:
+
+    curl --trace-ascii d.txt --trace-time http://example.com/
+
+## See which Transfer
+
+ When doing parallel transfers, it is relevant to see which transfer is doing
+ what. When response headers are received (and logged) you need to know which
+ transfer these are for.
+ [`--trace-ids`](https://curl.se/docs/manpage.html#--trace-ids) option is what
+ you need. It prepends the transfer and connection identifier to each trace
+ output line:
+
+    curl --trace-ascii d.txt --trace-ids http://example.com/
+
+## See the Response
+
+ By default curl sends the response to stdout. You need to redirect it
+ somewhere to avoid that, most often that is done with `-o` or `-O`.
+
+# URL
+
+## Spec
+
+ The Uniform Resource Locator format is how you specify the address of a
+ particular resource on the Internet. You know these, you have seen URLs like
+ https://curl.se or https://example.com a million times. RFC 3986 is the
+ canonical spec. The formal name is not URL, it is **URI**.
+
+## Host
+
+ The hostname is usually resolved using DNS or your /etc/hosts file to an IP
+ address and that is what curl communicates with. Alternatively you specify
+ the IP address directly in the URL instead of a name.
+
+ For development and other trying out situations, you can point to a different
+ IP address for a hostname than what would otherwise be used, by using curl's
+ [`--resolve`](https://curl.se/docs/manpage.html#--resolve) option:
+
+    curl --resolve www.example.org:80:127.0.0.1 http://www.example.org/
+
+## Port number
+
+ Each protocol curl supports operates on a default port number, be it over TCP
+ or in some cases UDP. Normally you do not have to take that into
+ consideration, but at times you run test servers on other ports or
+ similar. Then you can specify the port number in the URL with a colon and a
+ number immediately following the hostname. Like when doing HTTP to port
+ 1234:
+
+    curl http://www.example.org:1234/
+
+ The port number you specify in the URL is the number that the server uses to
+ offer its services. Sometimes you may use a proxy, and then you may
+ need to specify that proxy's port number separately from what curl needs to
+ connect to the server. Like when using an HTTP proxy on port 4321:
+
+    curl --proxy http://proxy.example.org:4321 http://remote.example.org/
+
+## Username and password
+
+ Some services are setup to require HTTP authentication and then you need to
+ provide name and password which is then transferred to the remote site in
+ various ways depending on the exact authentication protocol used.
+
+ You can opt to either insert the user and password in the URL or you can
+ provide them separately:
+
+    curl http://user:password@example.org/
+
+ or
+
+    curl -u user:password http://example.org/
+
+ You need to pay attention that this kind of HTTP authentication is not what
+ is usually done and requested by user-oriented websites these days. They tend
+ to use forms and cookies instead.
+
+## Path part
+
+ The path part is just sent off to the server to request that it sends back
+ the associated response. The path is what is to the right side of the slash
+ that follows the hostname and possibly port number.
+
+# Fetch a page
+
+## GET
+
+ The simplest and most common request/operation made using HTTP is to GET a
+ URL. The URL could itself refer to a webpage, an image or a file. The client
+ issues a GET request to the server and receives the document it asked for.
+ If you issue the command line
+
+    curl https://curl.se
+
+ you get a webpage returned in your terminal window. The entire HTML document
+ this URL identifies.
+
+ All HTTP replies contain a set of response headers that are normally hidden,
+ use curl's [`--include`](https://curl.se/docs/manpage.html#-i) (`-i`)
+ option to display them as well as the rest of the document.
+
+## HEAD
+
+ You can ask the remote server for ONLY the headers by using the
+ [`--head`](https://curl.se/docs/manpage.html#-I) (`-I`) option which makes
+ curl issue a HEAD request. In some special cases servers deny the HEAD method
+ while others still work, which is a particular kind of annoyance.
+
+ The HEAD method is defined and made so that the server returns the headers
+ exactly the way it would do for a GET, but without a body. It means that you
+ may see a `Content-Length:` in the response headers, but there must not be an
+ actual body in the HEAD response.
+
+## Multiple URLs in a single command line
+
+ A single curl command line may involve one or many URLs. The most common case
+ is probably to just use one, but you can specify any amount of URLs. Yes any.
+ No limits. You then get requests repeated over and over for all the given
+ URLs.
+
+ Example, send two GET requests:
+
+    curl http://url1.example.com http://url2.example.com
+
+ If you use [`--data`](https://curl.se/docs/manpage.html#-d) to POST to
+ the URL, using multiple URLs means that you send that same POST to all the
+ given URLs.
+
+ Example, send two POSTs:
+
+    curl --data name=curl http://url1.example.com http://url2.example.com
+
+
+## Multiple HTTP methods in a single command line
+
+ Sometimes you need to operate on several URLs in a single command line and do
+ different HTTP methods on each. For this, you might enjoy the
+ [`--next`](https://curl.se/docs/manpage.html#-:) option. It is basically a
+ separator that separates a bunch of options from the next. All the URLs
+ before `--next` get the same method and get all the POST data merged into
+ one.
+
+ When curl reaches the `--next` on the command line, it resets the method and
+ the POST data and allow a new set.
+
+ Perhaps this is best shown with a few examples. To send first a HEAD and then
+ a GET:
+
+    curl -I http://example.com --next http://example.com
+
+ To first send a POST and then a GET:
+
+    curl -d score=10 http://example.com/post.cgi --next http://example.com/results.html
+
+# HTML forms
+
+## Forms explained
+
+ Forms are the general way a website can present an HTML page with fields for
+ the user to enter data in, and then press some kind of 'OK' or 'Submit'
+ button to get that data sent to the server. The server then typically uses
+ the posted data to decide how to act. Like using the entered words to search
+ in a database, or to add the info in a bug tracking system, display the
+ entered address on a map or using the info as a login-prompt verifying that
+ the user is allowed to see what it is about to see.
+
+ Of course there has to be some kind of program on the server end to receive
+ the data you send. You cannot just invent something out of the air.
+
+## GET
+
+ A GET-form uses the method GET, as specified in HTML like:
+
+```html
+<form method="GET" action="junk.cgi">
+  <input type=text name="birthyear">
+  <input type=submit name=press value="OK">
+</form>
+```
+
+ In your favorite browser, this form appears with a text box to fill in and a
+ press-button labeled "OK". If you fill in '1905' and press the OK button,
+ your browser then creates a new URL to get for you. The URL gets
+ `junk.cgi?birthyear=1905&press=OK` appended to the path part of the previous
+ URL.
+
+ If the original form was seen on the page `www.example.com/when/birth.html`,
+ the second page you get becomes
+ `www.example.com/when/junk.cgi?birthyear=1905&press=OK`.
+
+ Most search engines work this way.
+
+ To make curl do the GET form post for you, just enter the expected created
+ URL:
+
+    curl "http://www.example.com/when/junk.cgi?birthyear=1905&press=OK"
+
+## POST
+
+ The GET method makes all input field names get displayed in the URL field of
+ your browser. That is generally a good thing when you want to be able to
+ bookmark that page with your given data, but it is an obvious disadvantage if
+ you entered secret information in one of the fields or if there are a large
+ amount of fields creating a long and unreadable URL.
+
+ The HTTP protocol then offers the POST method. This way the client sends the
+ data separated from the URL and thus you do not see any of it in the URL
+ address field.
+
+ The form would look similar to the previous one:
+
+```html
+<form method="POST" action="junk.cgi">
+  <input type=text name="birthyear">
+  <input type=submit name=press value=" OK ">
+</form>
+```
+
+ And to use curl to post this form with the same data filled in as before, we
+ could do it like:
+
+    curl --data "birthyear=1905&press=%20OK%20" http://www.example.com/when/junk.cgi
+
+ This kind of POST uses the Content-Type `application/x-www-form-urlencoded`
+ and is the most widely used POST kind.
+
+ The data you send to the server MUST already be properly encoded, curl does
+ not do that for you. For example, if you want the data to contain a space,
+ you need to replace that space with `%20`, etc. Failing to comply with this
+ most likely causes your data to be received wrongly and messed up.
+
+ Recent curl versions can in fact url-encode POST data for you, like this:
+
+    curl --data-urlencode "name=I am Daniel" http://www.example.com
+
+ If you repeat `--data` several times on the command line, curl concatenates
+ all the given data pieces - and put a `&` symbol between each data segment.
+
+## File Upload POST
+
+ Back in late 1995 they defined an additional way to post data over HTTP. It
+ is documented in the RFC 1867, why this method sometimes is referred to as
+ RFC 1867-posting.
+
+ This method is mainly designed to better support file uploads. A form that
+ allows a user to upload a file could be written like this in HTML:
+
+    <form method="POST" enctype='multipart/form-data' action="upload.cgi">
+      <input name=upload type=file>
+      <input type=submit name=press value="OK">
+    </form>
+
+ This clearly shows that the Content-Type about to be sent is
+ `multipart/form-data`.
+
+ To post to a form like this with curl, you enter a command line like:
+
+    curl --form upload=@localfilename --form press=OK [URL]
+
+## Hidden Fields
+
+ A common way for HTML based applications to pass state information between
+ pages is to add hidden fields to the forms. Hidden fields are already filled
+ in, they are not displayed to the user and they get passed along just as all
+ the other fields.
+
+ A similar example form with one visible field, one hidden field and one
+ submit button could look like:
+
+```html
+<form method="POST" action="foobar.cgi">
+  <input type=text name="birthyear">
+  <input type=hidden name="person" value="daniel">
+  <input type=submit name="press" value="OK">
+</form>
+```
+
+ To POST this with curl, you do not have to think about if the fields are
+ hidden or not. To curl they are all the same:
+
+    curl --data "birthyear=1905&press=OK&person=daniel" [URL]
+
+## Figure Out What A POST Looks Like
+
+ When you are about to fill in a form and send it to a server by using curl
+ instead of a browser, you are of course interested in sending a POST exactly
+ the way your browser does.
+
+ An easy way to get to see this, is to save the HTML page with the form on
+ your local disk, modify the 'method' to a GET, and press the submit button
+ (you could also change the action URL if you want to).
+
+ You then clearly see the data get appended to the URL, separated with a
+ `?`-letter as GET forms are supposed to.
+
+# HTTP upload
+
+## PUT
+
+ Perhaps the best way to upload data to an HTTP server is to use PUT. Then
+ again, this of course requires that someone put a program or script on the
+ server end that knows how to receive an HTTP PUT stream.
+
+ Put a file to an HTTP server with curl:
+
+    curl --upload-file uploadfile http://www.example.com/receive.cgi
+
+# HTTP Authentication
+
+## Basic Authentication
+
+ HTTP Authentication is the ability to tell the server your username and
+ password so that it can verify that you are allowed to do the request you are
+ doing. The Basic authentication used in HTTP (which is the type curl uses by
+ default) is **plain text** based, which means it sends username and password
+ only slightly obfuscated, but still fully readable by anyone that sniffs on
+ the network between you and the remote server.
+
+ To tell curl to use a user and password for authentication:
+
+    curl --user name:password http://www.example.com
+
+## Other Authentication
+
+ The site might require a different authentication method (check the headers
+ returned by the server), and then
+ [`--ntlm`](https://curl.se/docs/manpage.html#--ntlm),
+ [`--digest`](https://curl.se/docs/manpage.html#--digest),
+ [`--negotiate`](https://curl.se/docs/manpage.html#--negotiate) or even
+ [`--anyauth`](https://curl.se/docs/manpage.html#--anyauth) might be
+ options that suit you.
+
+## Proxy Authentication
+
+ Sometimes your HTTP access is only available through the use of an HTTP
+ proxy. This seems to be especially common at various companies. An HTTP proxy
+ may require its own user and password to allow the client to get through to
+ the Internet. To specify those with curl, run something like:
+
+    curl --proxy-user proxyuser:proxypassword curl.se
+
+ If your proxy requires the authentication to be done using the NTLM method,
+ use [`--proxy-ntlm`](https://curl.se/docs/manpage.html#--proxy-ntlm), if
+ it requires Digest use
+ [`--proxy-digest`](https://curl.se/docs/manpage.html#--proxy-digest).
+
+ If you use any one of these user+password options but leave out the password
+ part, curl prompts for the password interactively.
+
+## Hiding credentials
+
+ Do note that when a program is run, its parameters might be possible to see
+ when listing the running processes of the system. Thus, other users may be
+ able to watch your passwords if you pass them as plain command line
+ options. There are ways to circumvent this.
+
+ It is worth noting that while this is how HTTP Authentication works, many
+ websites do not use this concept when they provide logins etc. See the Web
+ Login chapter further below for more details on that.
+
+# More HTTP Headers
+
+## Referer
+
+ An HTTP request may include a 'referer' field (yes it is misspelled), which
+ can be used to tell from which URL the client got to this particular
+ resource. Some programs/scripts check the referer field of requests to verify
+ that this was not arriving from an external site or an unknown page. While
+ this is a stupid way to check something so easily forged, many scripts still
+ do it. Using curl, you can put anything you want in the referer-field and
+ thus more easily be able to fool the server into serving your request.
+
+ Use curl to set the referer field with:
+
+    curl --referer http://www.example.come http://www.example.com
+
+## User Agent
+
+ Similar to the referer field, all HTTP requests may set the User-Agent
+ field. It names what user agent (client) that is being used. Many
+ applications use this information to decide how to display pages. Silly web
+ programmers try to make different pages for users of different browsers to
+ make them look the best possible for their particular browsers. They usually
+ also do different kinds of JavaScript etc.
+
+ At times, you may learn that getting a page with curl does not return the
+ same page that you see when getting the page with your browser. Then you know
+ it is time to set the User Agent field to fool the server into thinking you
+ are one of those browsers.
+
+ By default, curl uses curl/VERSION, such as User-Agent: curl/8.11.0.
+
+ To make curl look like Internet Explorer 5 on a Windows 2000 box:
+
+    curl --user-agent "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)" [URL]
+
+ Or why not look like you are using Netscape 4.73 on an old Linux box:
+
+    curl --user-agent "Mozilla/4.73 [en] (X11; U; Linux 2.2.15 i686)" [URL]
+
+## Redirects
+
+## Location header
+
+ When a resource is requested from a server, the reply from the server may
+ include a hint about where the browser should go next to find this page, or a
+ new page keeping newly generated output. The header that tells the browser to
+ redirect is `Location:`.
+
+ curl does not follow `Location:` headers by default, but simply displays such
+ pages in the same manner it displays all HTTP replies. It does however
+ feature an option that makes it attempt to follow the `Location:` pointers.
+
+ To tell curl to follow a Location:
+
+    curl --location http://www.example.com
+
+ If you use curl to POST to a site that immediately redirects you to another
+ page, you can safely use [`--location`](https://curl.se/docs/manpage.html#-L)
+ (`-L`) and `--data`/`--form` together. curl only uses POST in the first
+ request, and then revert to GET in the following operations.
+
+## Other redirects
+
+ Browsers typically support at least two other ways of redirects that curl
+ does not: first the html may contain a meta refresh tag that asks the browser
+ to load a specific URL after a set number of seconds, or it may use
+ JavaScript to do it.
+
+# Cookies
+
+## Cookie Basics
+
+ The way the web browsers do "client side state control" is by using
+ cookies. Cookies are just names with associated contents. The cookies are
+ sent to the client by the server. The server tells the client for what path
+ and hostname it wants the cookie sent back, and it also sends an expiration
+ date and a few more properties.
+
+ When a client communicates with a server with a name and path as previously
+ specified in a received cookie, the client sends back the cookies and their
+ contents to the server, unless of course they are expired.
+
+ Many applications and servers use this method to connect a series of requests
+ into a single logical session. To be able to use curl in such occasions, we
+ must be able to record and send back cookies the way the web application
+ expects them. The same way browsers deal with them.
+
+## Cookie options
+
+ The simplest way to send a few cookies to the server when getting a page with
+ curl is to add them on the command line like:
+
+    curl --cookie "name=Daniel" http://www.example.com
+
+ Cookies are sent as common HTTP headers. This is practical as it allows curl
+ to record cookies simply by recording headers. Record cookies with curl by
+ using the [`--dump-header`](https://curl.se/docs/manpage.html#-D) (`-D`)
+ option like:
+
+    curl --dump-header headers_and_cookies http://www.example.com
+
+ (Take note that the
+ [`--cookie-jar`](https://curl.se/docs/manpage.html#-c) option described
+ below is a better way to store cookies.)
+
+ curl has a full blown cookie parsing engine built-in that comes in use if you
+ want to reconnect to a server and use cookies that were stored from a
+ previous connection (or hand-crafted manually to fool the server into
+ believing you had a previous connection). To use previously stored cookies,
+ you run curl like:
+
+    curl --cookie stored_cookies_in_file http://www.example.com
+
+ curl's "cookie engine" gets enabled when you use the
+ [`--cookie`](https://curl.se/docs/manpage.html#-b) option. If you only
+ want curl to understand received cookies, use `--cookie` with a file that
+ does not exist. Example, if you want to let curl understand cookies from a
+ page and follow a location (and thus possibly send back cookies it received),
+ you can invoke it like:
+
+    curl --cookie nada --location http://www.example.com
+
+ curl has the ability to read and write cookie files that use the same file
+ format that Netscape and Mozilla once used. It is a convenient way to share
+ cookies between scripts or invokes. The `--cookie` (`-b`) switch
+ automatically detects if a given file is such a cookie file and parses it,
+ and by using the `--cookie-jar` (`-c`) option you make curl write a new
+ cookie file at the end of an operation:
+
+    curl --cookie cookies.txt --cookie-jar newcookies.txt \
+      http://www.example.com
+
+# HTTPS
+
+## HTTPS is HTTP secure
+
+ There are a few ways to do secure HTTP transfers. By far the most common
+ protocol for doing this is what is generally known as HTTPS, HTTP over
+ SSL. SSL encrypts all the data that is sent and received over the network and
+ thus makes it harder for attackers to spy on sensitive information.
+
+ SSL (or TLS as the current version of the standard is called) offers a set of
+ advanced features to do secure transfers over HTTP.
+
+ curl supports encrypted fetches when built to use a TLS library and it can be
+ built to use one out of a fairly large set of libraries - `curl -V` shows
+ which one your curl was built to use (if any). To get a page from an HTTPS
+ server, simply run curl like:
+
+    curl https://secure.example.com
+
+## Certificates
+
+ In the HTTPS world, you use certificates to validate that you are the one you
+ claim to be, as an addition to normal passwords. curl supports client- side
+ certificates. All certificates are locked with a passphrase, which you need
+ to enter before the certificate can be used by curl. The passphrase can be
+ specified on the command line or if not, entered interactively when curl
+ queries for it. Use a certificate with curl on an HTTPS server like:
+
+    curl --cert mycert.pem https://secure.example.com
+
+ curl also tries to verify that the server is who it claims to be, by
+ verifying the server's certificate against a locally stored CA cert bundle.
+ Failing the verification causes curl to deny the connection. You must then
+ use [`--insecure`](https://curl.se/docs/manpage.html#-k) (`-k`) in case you
+ want to tell curl to ignore that the server cannot be verified.
+
+ More about server certificate verification and ca cert bundles can be read in
+ the [`SSLCERTS` document](https://curl.se/docs/sslcerts.html).
+
+ At times you may end up with your own CA cert store and then you can tell
+ curl to use that to verify the server's certificate:
+
+    curl --cacert ca-bundle.pem https://example.com/
+
+# Custom Request Elements
+
+## Modify method and headers
+
+ Doing fancy stuff, you may need to add or change elements of a single curl
+ request.
+
+ For example, you can change the POST method to `PROPFIND` and send the data
+ as `Content-Type: text/xml` (instead of the default `Content-Type`) like
+ this:
+
+    curl --data "<xml>" --header "Content-Type: text/xml" \
+      --request PROPFIND example.com
+
+ You can delete a default header by providing one without content. Like you
+ can ruin the request by chopping off the `Host:` header:
+
+    curl --header "Host:" http://www.example.com
+
+ You can add headers the same way. Your server may want a `Destination:`
+ header, and you can add it:
+
+    curl --header "Destination: http://nowhere" http://example.com
+
+## More on changed methods
+
+ It should be noted that curl selects which methods to use on its own
+ depending on what action to ask for. `-d` makes a POST, `-I` makes a HEAD and
+ so on. If you use the [`--request`](https://curl.se/docs/manpage.html#-X) /
+ `-X` option you can change the method keyword curl selects, but you do not
+ modify curl's behavior. This means that if you for example use -d "data" to
+ do a POST, you can modify the method to a `PROPFIND` with `-X` and curl still
+ thinks it sends a POST. You can change the normal GET to a POST method by
+ simply adding `-X POST` in a command line like:
+
+    curl -X POST http://example.org/
+
+ curl however still acts as if it sent a GET so it does not send any request
+ body etc.
+
+# Web Login
+
+## Some login tricks
+
+ While not strictly just HTTP related, it still causes a lot of people
+ problems so here's the executive run-down of how the vast majority of all
+ login forms work and how to login to them using curl.
+
+ It can also be noted that to do this properly in an automated fashion, you
+ most certainly need to script things and do multiple curl invokes etc.
+
+ First, servers mostly use cookies to track the logged-in status of the
+ client, so you need to capture the cookies you receive in the responses.
+ Then, many sites also set a special cookie on the login page (to make sure
+ you got there through their login page) so you should make a habit of first
+ getting the login-form page to capture the cookies set there.
+
+ Some web-based login systems feature various amounts of JavaScript, and
+ sometimes they use such code to set or modify cookie contents. Possibly they
+ do that to prevent programmed logins, like this manual describes how to...
+ Anyway, if reading the code is not enough to let you repeat the behavior
+ manually, capturing the HTTP requests done by your browsers and analyzing the
+ sent cookies is usually a working method to work out how to shortcut the
+ JavaScript need.
+
+ In the actual `<form>` tag for the login, lots of sites fill-in
+ random/session or otherwise secretly generated hidden tags and you may need
+ to first capture the HTML code for the login form and extract all the hidden
+ fields to be able to do a proper login POST. Remember that the contents need
+ to be URL encoded when sent in a normal POST.
+
+# Debug
+
+## Some debug tricks
+
+ Many times when you run curl on a site, you notice that the site does not
+ seem to respond the same way to your curl requests as it does to your
+ browser's.
+
+ Then you need to start making your curl requests more similar to your
+ browser's requests:
+
+ - Use the `--trace-ascii` option to store fully detailed logs of the requests
+   for easier analyzing and better understanding
+
+ - Make sure you check for and use cookies when needed (both reading with
+   `--cookie` and writing with `--cookie-jar`)
+
+ - Set user-agent (with [`-A`](https://curl.se/docs/manpage.html#-A)) to
+   one like a recent popular browser does
+
+ - Set referer (with [`-E`](https://curl.se/docs/manpage.html#-E)) like
+   it is set by the browser
+
+ - If you use POST, make sure you send all the fields and in the same order as
+   the browser does it.
+
+## Check what the browsers do
+
+ A good helper to make sure you do this right, is the web browsers' developers
+ tools that let you view all headers you send and receive (even when using
+ HTTPS).
+
+ A more raw approach is to capture the HTTP traffic on the network with tools
+ such as Wireshark or tcpdump and check what headers that were sent and
+ received by the browser. (HTTPS forces you to use `SSLKEYLOGFILE` to do
+ that.)

+# URL syntax and their use in curl
+
+## Specifications
+
+The official "URL syntax" is primarily defined in these two different
+specifications:
+
+ - [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986) (although URL is called
+   "URI" in there)
+ - [The WHATWG URL Specification](https://url.spec.whatwg.org/)
+
+RFC 3986 is the earlier one, and curl has always tried to adhere to that one
+(since it shipped in January 2005).
+
+The WHATWG URL spec was written later, is incompatible with the RFC 3986 and
+changes over time.
+
+## Variations
+
+URL parsers as implemented in browsers, libraries and tools usually opt to
+support one of the mentioned specifications. Bugs, differences in
+interpretations and the moving nature of the WHATWG spec does however make it
+unlikely that multiple parsers treat URLs the same way.
+
+## Security
+
+Due to the inherent differences between URL parser implementations, it is
+considered a security risk to mix different implementations and assume the
+same behavior.
+
+For example, if you use one parser to check if a URL uses a good hostname or
+the correct auth field, and then pass on that same URL to a *second* parser,
+there is always a risk it treats the same URL differently. There is no right
+and wrong in URL land, only differences of opinions.
+
+libcurl offers a separate API to its URL parser for this reason, among others.
+
+Applications may at times find it convenient to allow users to specify URLs
+for various purposes and that string would then end up fed to curl. Getting a
+URL from an external untrusted party and using it with curl brings several
+security concerns:
+
+1. If you have an application that runs as or in a server application, getting
+   an unfiltered URL can trick your application to access a local resource
+   instead of a remote resource. Protecting yourself against localhost accesses
+   is hard when accepting user provided URLs.
+
+2. Such custom URLs can access other ports than you planned as port numbers
+   are part of the regular URL format. The combination of a local host and a
+   custom port number can allow external users to play tricks with your local
+   services.
+
+3. Such a URL might use other schemes than you thought of or planned for.
+
+## "RFC 3986 plus"
+
+curl recognizes a URL syntax that we call "RFC 3986 plus". It is grounded on
+the well established RFC 3986 to make sure previously written command lines
+and curl using scripts remain working.
+
+curl's URL parser allows a few deviations from the spec in order to
+inter-operate better with URLs that appear in the wild.
+
+### Spaces
+
+A URL provided to curl cannot contain spaces. They need to be provided URL
+encoded to be accepted in a URL by curl.
+
+An exception to this rule: `Location:` response headers that indicate to a
+client where a resource has been redirected to, sometimes contain spaces. This
+is a violation of RFC 3986 but is fine in the WHATWG spec. curl handles these
+by re-encoding them to `%20`.
+
+### Non-ASCII
+
+Byte values in a provided URL that are outside of the printable ASCII range
+are percent-encoded by curl.
+
+### Multiple slashes
+
+An absolute URL always starts with a "scheme" followed by a colon. For all the
+schemes curl supports, the colon must be followed by two slashes according to
+RFC 3986 but not according to the WHATWG spec - which allows one to infinity
+amount.
+
+curl allows one, two or three slashes after the colon to still be considered a
+valid URL.
+
+### "scheme-less"
+
+curl supports "URLs" that do not start with a scheme. This is not supported by
+any of the specifications. This is a shortcut to entering URLs that was
+supported by browsers early on and has been mimicked by curl.
+
+Based on what the hostname starts with, curl "guesses" what protocol to use:
+
+ - `ftp.` means FTP
+ - `dict.` means DICT
+ - `ldap.` means LDAP
+ - `imap.` means IMAP
+ - `smtp.` means SMTP
+ - `pop3.` means POP3
+ - all other means HTTP
+
+### Globbing letters
+
+The curl command line tool supports "globbing" of URLs. It means that you can
+create ranges and lists using `[N-M]` and `{one,two,three}` sequences. The
+letters used for this (`[]{}`) are reserved in RFC 3986 and can therefore not
+legitimately be part of such a URL.
+
+They are however not reserved or special in the WHATWG specification, so
+globbing can mess up such URLs. Globbing can be turned off for such occasions
+(using `--globoff`).
+
+# URL syntax details
+
+A URL may consist of the following components - many of them are optional:
+
+    [scheme][divider][userinfo][hostname][port number][path][query][fragment]
+
+Each component is separated from the following component with a divider
+character or string.
+
+For example, this could look like:
+
+    http://user:password@www.example.com:80/index.html?foo=bar#top
+
+## Scheme
+
+The scheme specifies the protocol to use. A curl build can support a few or
+many different schemes. You can limit what schemes curl should accept.
+
+curl supports the following schemes on URLs specified to transfer. They are
+matched case insensitively:
+
+`dict`, `file`, `ftp`, `ftps`, `gopher`, `gophers`, `http`, `https`, `imap`,
+`imaps`, `ldap`, `ldaps`, `mqtt`, `pop3`, `pop3s`, `rtmp`, `rtmpe`, `rtmps`,
+`rtmpt`, `rtmpte`, `rtmpts`, `rtsp`, `smb`, `smbs`, `smtp`, `smtps`, `telnet`,
+`tftp`
+
+When the URL is specified to identify a proxy, curl recognizes the following
+schemes:
+
+`http`, `https`, `socks4`, `socks4a`, `socks5`, `socks5h`, `socks`
+
+## Userinfo
+
+The userinfo field can be used to set username and password for
+authentication purposes in this transfer. The use of this field is discouraged
+since it often means passing around the password in plain text and is thus a
+security risk.
+
+URLs for IMAP, POP3 and SMTP also support *login options* as part of the
+userinfo field. They are provided as a semicolon after the password and then
+the options.
+
+## Hostname
+
+The hostname part of the URL contains the address of the server that you want
+to connect to. This can be the fully qualified domain name of the server, the
+local network name of the machine on your network or the IP address of the
+server or machine represented by either an IPv4 or IPv6 address (within
+brackets). For example:
+
+    http://www.example.com/
+
+    http://hostname/
+
+    http://192.168.0.1/
+
+    http://[2001:1890:1112:1::20]/
+
+### "localhost"
+
+Starting in curl 7.77.0, curl uses loopback IP addresses for the name
+`localhost`: `127.0.0.1` and `::1`. It does not resolve the name using the
+resolver functions.
+
+This is done to make sure the host accessed is truly the localhost - the local
+machine.
+
+### IDNA
+
+If curl was built with International Domain Name (IDN) support, it can also
+handle hostnames using non-ASCII characters.
+
+When built with libidn2, curl uses the IDNA 2008 standard. This is equivalent
+to the WHATWG URL spec, but differs from certain browsers that use IDNA 2003
+Transitional Processing. The two standards have a huge overlap but differ
+slightly, perhaps most famously in how they deal with the
+[German "double s"](https://en.wikipedia.org/wiki/%c3%9f).
+
+When WinIDN is used, curl uses IDNA 2003 Transitional Processing, like the rest
+of Windows.
+
+## Port number
+
+If there is a colon after the hostname, that should be followed by the port
+number to use. 1 - 65535. curl also supports a blank port number field - but
+only if the URL starts with a scheme.
+
+If the port number is not specified in the URL, curl uses a default port
+number based on the provide scheme:
+
+DICT 2628, FTP 21, FTPS 990, GOPHER 70, GOPHERS 70, HTTP 80, HTTPS 443,
+IMAP 132, IMAPS 993, LDAP 369, LDAPS 636, MQTT 1883, POP3 110, POP3S 995,
+RTMP 1935, RTMPS 443, RTMPT 80, RTSP 554, SCP 22, SFTP 22, SMB 445, SMBS 445,
+SMTP 25, SMTPS 465, TELNET 23, TFTP 69
+
+# Scheme specific behaviors
+
+## FTP
+
+The path part of an FTP request specifies the file to retrieve and from which
+directory. If the file part is omitted then libcurl downloads the directory
+listing for the directory specified. If the directory is omitted then the
+directory listing for the root / home directory is returned.
+
+FTP servers typically put the user in its "home directory" after login, which
+then differs between users. To explicitly specify the root directory of an FTP
+server, start the path with double slash `//` or `/%2f` (2F is the hexadecimal
+value of the ASCII code for the slash).
+
+## FILE
+
+When a `FILE://` URL is accessed on Windows systems, it can be crafted in a
+way so that Windows attempts to connect to a (remote) machine when curl wants
+to read or write such a path.
+
+curl only allows the hostname part of a FILE URL to be one out of these three
+alternatives: `localhost`, `127.0.0.1` or blank ("", zero characters).
+Anything else makes curl fail to parse the URL.
+
+### Windows-specific FILE details
+
+curl accepts that the FILE URL's path starts with a "drive letter". That is a
+single letter `a` to `z` followed by a colon or a pipe character (`|`).
+
+The Windows operating system itself converts some file accesses to perform
+network accesses over SMB/CIFS, through several different file path patterns.
+This way, a `file://` URL passed to curl *might* be converted into a network
+access inadvertently and unknowingly to curl. This is a Windows feature curl
+cannot control or disable.
+
+## IMAP
+
+The path part of an IMAP request not only specifies the mailbox to list or
+select, but can also be used to check the `UIDVALIDITY` of the mailbox, to
+specify the `UID`, `SECTION` and `PARTIAL` octets of the message to fetch and
+to specify what messages to search for.
+
+A top level folder list:
+
+    imap://user:password@mail.example.com
+
+A folder list on the user's inbox:
+
+    imap://user:password@mail.example.com/INBOX
+
+Select the user's inbox and fetch message with `uid = 1`:
+
+    imap://user:password@mail.example.com/INBOX/;UID=1
+
+Select the user's inbox and fetch the first message in the mail box:
+
+    imap://user:password@mail.example.com/INBOX/;MAILINDEX=1
+
+Select the user's inbox, check the `UIDVALIDITY` of the mailbox is 50 and
+fetch message 2 if it is:
+
+    imap://user:password@mail.example.com/INBOX;UIDVALIDITY=50/;UID=2
+
+Select the user's inbox and fetch the text portion of message 3:
+
+    imap://user:password@mail.example.com/INBOX/;UID=3/;SECTION=TEXT
+
+Select the user's inbox and fetch the first 1024 octets of message 4:
+
+    imap://user:password@mail.example.com/INBOX/;UID=4/;PARTIAL=0.1024
+
+Select the user's inbox and check for NEW messages:
+
+    imap://user:password@mail.example.com/INBOX?NEW
+
+Select the user's inbox and search for messages containing "shadows" in the
+subject line:
+
+    imap://user:password@mail.example.com/INBOX?SUBJECT%20shadows
+
+Searching via the query part of the URL `?` is a search request for the
+results to be returned as message sequence numbers (`MAILINDEX`). It is
+possible to make a search request for results to be returned as unique ID
+numbers (`UID`) by using a custom curl request via `-X`. `UID` numbers are
+unique per session (and multiple sessions when `UIDVALIDITY` is the same). For
+example, if you are searching for `"foo bar"` in header+body (`TEXT`) and you
+want the matching `MAILINDEX` numbers returned then you could search via URL:
+
+    imap://user:password@mail.example.com/INBOX?TEXT%20%22foo%20bar%22
+
+If you want matching `UID` numbers you have to use a custom request:
+
+    imap://user:password@mail.example.com/INBOX -X "UID SEARCH TEXT \"foo bar\""
+
+For more information about IMAP commands please see RFC 9051. For more
+information about the individual components of an IMAP URL please see RFC 5092.
+
+* Note old curl versions would `FETCH` by message sequence number when `UID`
+was specified in the URL. That was a bug fixed in 7.62.0, which added
+`MAILINDEX` to `FETCH` by mail sequence number.
+
+## LDAP
+
+The path part of an LDAP request can be used to specify the: Distinguished
+Name, Attributes, Scope, Filter and Extension for an LDAP search. Each field
+is separated by a question mark and when that field is not required an empty
+string with the question mark separator should be included.
+
+Search for the `DN` as `My Organization`:
+
+    ldap://ldap.example.com/o=My%20Organization
+
+the same search but only return `postalAddress` attributes:
+
+    ldap://ldap.example.com/o=My%20Organization?postalAddress
+
+Search for an empty `DN` and request information about the
+`rootDomainNamingContext` attribute for an Active Directory server:
+
+    ldap://ldap.example.com/?rootDomainNamingContext
+
+For more information about the individual components of an LDAP URL please see
+[RFC 4516](https://datatracker.ietf.org/doc/html/rfc4516).
+
+## POP3
+
+The path part of a POP3 request specifies the message ID to retrieve. If the
+ID is not specified then a list of waiting messages is returned instead.
+
+## SCP
+
+The path part of an SCP URL specifies the path and file to retrieve or
+upload. The file is taken as an absolute path from the root directory on the
+server.
+
+To specify a path relative to the user's home directory on the server, prepend
+`~/` to the path portion.
+
+## SFTP
+
+The path part of an SFTP URL specifies the file to retrieve or upload. If the
+path ends with a slash (`/`) then a directory listing is returned instead of a
+file. If the path is omitted entirely then the directory listing for the root
+/ home directory is returned.
+
+## SMB
+The path part of an SMB request specifies the file to retrieve and from what
+share and directory or the share to upload to and as such, may not be omitted.
+If the username is embedded in the URL then it must contain the domain name
+and as such, the backslash must be URL encoded as %2f.
+
+When uploading to SMB, the size of the file needs to be known ahead of time,
+meaning that you can upload a file passed to curl over a pipe like stdin.
+
+curl supports SMB version 1 (only)
+
+## SMTP
+
+The path part of an SMTP request specifies the hostname to present during
+communication with the mail server. If the path is omitted, then libcurl
+attempts to resolve the local computer's hostname. However, this may not
+return the fully qualified domain name that is required by some mail servers
+and specifying this path allows you to set an alternative name, such as your
+machine's fully qualified domain name, which you might have obtained from an
+external function such as gethostname or getaddrinfo.
+
+The default smtp port is 25. Some servers use port 587 as an alternative.
+
+## RTMP
+
+There is no official URL spec for RTMP so libcurl uses the URL syntax supported
+by the underlying librtmp library. It has a syntax where it wants a
+traditional URL, followed by a space and a series of space-separated
+`name=value` pairs.
+
+While space is not typically a "legal" letter, libcurl accepts them. When a
+user wants to pass in a `#` (hash) character it is treated as a fragment and
+it gets cut off by libcurl if provided literally. You have to escape it by
+providing it as backslash and its ASCII value in hexadecimal: `\23`.
