+# NAME
+
+CURLOPT_SSL_SIGNATURE_ALGORITHMS - signature algorithms to use for TLS
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_SIGNATURE_ALGORITHMS, char *list);
+~~~
+
+# DESCRIPTION
+
+Pass a char pointer, pointing to a null-terminated string holding the list of
+signature algorithms to use for the TLS connection. The list must be syntactically
+correct, it consists of one or more signature algorithm strings separated by colons.
+
+A valid example of a signature algorithms list with OpenSSL is:
+~~~
+"DSA+SHA256:rsa_pss_pss_sha256"
+~~~
+
+The application does not have to keep the string around after setting this
+option.
+
+Using this option multiple times makes the last set string override the
+previous ones. Set it to NULL to disable its use again.
+
+Works with OpenSSL and its BoringSSL fork (added in 8.14.0).
+
+# DEFAULT
+
+NULL, use built-in list
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+    curl_easy_setopt(curl, CURLOPT_SSL_SIGNATURE_ALGORITHMS,
+                     "DSA+SHA256:rsa_pss_pss_sha256");
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# HISTORY
+
+OpenSSL support added in 8.14.0.
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
