+# NAME
+
+CURLOPT_TLS13_CIPHERS - ciphers suites to use for TLS 1.3
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLS13_CIPHERS, char *list);
+~~~
+
+# DESCRIPTION
+
+Pass a char pointer, pointing to a null-terminated string holding the list of
+cipher suites to use for the TLS 1.3 connection. The list must be
+syntactically correct, it consists of one or more cipher suite strings
+separated by colons.
+
+For setting TLS 1.2 (1.1, 1.0) ciphers see CURLOPT_SSL_CIPHER_LIST(3).
+
+A valid example of a cipher list is:
+~~~c
+"TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256"
+~~~
+
+Find more details about cipher lists on this URL:
+
+ https://curl.se/docs/ssl-ciphers.html
+
+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 restore to internal default.
+
+# DEFAULT
+
+NULL, use internal built-in
+
+# %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_TLS13_CIPHERS,
+                     "TLS_CHACHA20_POLY1305_SHA256");
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}

+# HISTORY
+
+OpenSSL support added in 7.61.0, available when built with OpenSSL \>= 1.1.1.
+LibreSSL support added in 8.3.0, available when built with LibreSSL \>= 3.4.1.
+wolfSSL support added in 8.10.0.
+mbedTLS support added in 8.10.0, available when built with mbedTLS \>= 3.6.0.
+Rustls support added in 8.10.0.
+
+Before curl 8.10.0 with mbedTLS or wolfSSL, TLS 1.3 cipher suites were set
+by using the CURLOPT_SSL_CIPHER_LIST(3) option.
+
+# %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).
