CURLOPT_SSL_CIPHER_LIST(3) curl_easy_setopt options CURLOPT_SSL_CIPHER_LIST(3)NAMECURLOPT_SSL_CIPHER_LIST - specify ciphers to use for TLS
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_CIPHER_LIST, char
*list);
DESCRIPTION
Pass a char *, pointing to a zero terminated string holding the list of
ciphers to use for the SSL connection. The list must be syntactically
correct, it consists of one or more cipher strings separated by colons.
Commas or spaces are also acceptable separators but colons are normally
used, !, - and + can be used as operators.
For OpenSSL and GnuTLS valid examples of cipher lists include
'RC4-SHA', ´SHA1+DES´, 'TLSv1' and 'DEFAULT'. The default list is nor‐
mally set when you compile OpenSSL.
You'll find more details about cipher lists on this URL:
http://www.openssl.org/docs/apps/ciphers.html
For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5',
´rsa_aes_128_sha´, etc. With NSS you don't add/remove ciphers. If one
uses this option then all known ciphers are disabled and only those
passed in are enabled.

DEFAULT
NULL, use internal default
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
TODO
AVAILABILITY
If built TLS enabled.
RETURN VALUE
Returns CURLE_OK if TLS is supported, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
