# 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.
|
||
|
|
Schannel support added in 7.85.0.
|
||
|
|
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 where set
|
||
|
|
by using the CURLOPT_SSL_CIPHER_LIST(3) option.
|
||
