.TH CURLOPT_SSL_CIPHER_LIST 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_SSL_CIPHER_LIST \- specify ciphers to use for TLS
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_CIPHER_LIST, char *list);
|
|
.SH DESCRIPTION
|
|
Pass a char *, pointing to a null-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 normally set when you
|
|
compile OpenSSL.
|
|
|
|
You'll find more details about cipher lists on this URL:
|
|
|
|
https://curl.se/docs/ssl-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.
|
|
|
|
For WolfSSL, valid examples of cipher lists include
|
|
\'ECDHE-RSA-RC4-SHA\', 'AES256-SHA:AES256-SHA256', etc.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
.SH DEFAULT
|
|
NULL, use internal default
|
|
.SH PROTOCOLS
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
.SH EXAMPLE
|
|
.nf
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_SSL_CIPHER_LIST, "TLSv1");
|
|
ret = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
If built TLS enabled.
|
|
.SH 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.
