CURLOPT_PROXY_SSL_CIPHER_LIcurl_easy_setopt opCURLOPT_PROXY_SSL_CIPHER_LIST(3)

NAME
       CURLOPT_PROXY_SSL_CIPHER_LIST - specify ciphers to use for proxy TLS

SYNOPSIS
       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_CIPHER_LIST,
       char *list);

DESCRIPTION
       Pass a char *, pointing to a zero terminated string holding the list of
       ciphers  to use for the connection to the HTTPS proxy. The list must be
       syntactically correct, it consists of one or more cipher strings  sepa-
       rated  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:

        https://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.

       You'll find more details about the NSS cipher lists on this URL:

        http://git.fedora-
       hosted.org/cgit/mod_nss.git/plain/docs/mod_nss.html#Directives

       The application does not have to keep the string around  after  setting
       this option.

DEFAULT
       NULL, use internal default

PROTOCOLS
       All

EXAMPLE
       TODO

AVAILABILITY
       Added in 7.52.0

       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.
