NAME
CURLOPT_PROXY_TLS13_CIPHERS - ciphers suites for proxy TLS 1.3
SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLS13_CIPHERS, char *list);
DESCRIPTION
Pass a char *, pointing to a null-terminated string holding the list of cipher suites to use for the TLS 1.3 connection to a proxy. The list must be syntactically correct, it consists of one or more cipher suite strings separated by colons. you will find more details about cipher lists on this URL: https://curl.se/docs/ssl-ciphers.html This option is currently used only when curl is built to use OpenSSL 1.1.1 or later. If you are using a different SSL backend you can try setting TLS 1.3 cipher suites by using the CURLOPT_PROXY_SSL_CIPHER_LIST option. The application does not have to keep the string around after setting this option.
DEFAULT
NULL, use internal default
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); curl_easy_setopt(curl, CURLOPT_PROXY_TLS13_CIPHERS, "TLS_CHACHA20_POLY1305_SHA256"); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); }
AVAILABILITY
Added in 7.61.0. Available when built with OpenSSL >= 1.1.1.
RETURN VALUE
Returns CURLE_OK if supported, CURLE_NOT_BUILT_IN otherwise.
