CURLOPT_PROXY_TLS13_CIPHERS(3)                        curl_easy_setopt options

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 zero 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'll find more details about cipher lists on this URL: https://curl.haxx.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, "TLS13-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.
