NAME

6       CURLOPT_PROXY_TLS13_CIPHERS - ciphers suites for proxy TLS 1.3
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_PROXY_TLS13_CIPHERS,
12       char *list);
13

DESCRIPTION

15       Pass a char *, pointing to a null-terminated string holding the list of
16       cipher  suites  to  use for the TLS 1.3 connection to a proxy. The list
17       must be syntactically correct, it consists of one or more cipher  suite
18       strings separated by colons.
19
20       You'll find more details about cipher lists on this URL:
21
22        https://curl.se/docs/ssl-ciphers.html
23
24       This  option  is  currently used only when curl is built to use OpenSSL
25       1.1.1 or later. If you are using a different SSL backend  you  can  try
26       setting  TLS  1.3  cipher  suites  by  using  the CURLOPT_PROXY_SSL_CI‐
27       PHER_LIST option.
28
29       The application does not have to keep the string around  after  setting
30       this option.
31

DEFAULT

33       NULL, use internal default
34

PROTOCOLS

36       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE

39       CURL *curl = curl_easy_init();
40       if(curl) {
41         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
42         curl_easy_setopt(curl, CURLOPT_PROXY_TLS13_CIPHERS,
43                          "TLS13-CHACHA20-POLY1305-SHA256");
44         ret = curl_easy_perform(curl);
45         curl_easy_cleanup(curl);
46       }
