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
       CURL *curl = curl_easy_init();
       if(curl)	{
	 curl_easy_setopt(curl,	CURLOPT_URL, "https://example.com/");
	 curl_easy_setopt(curl,	CURLOPT_PROXY, "https://localhost");
	 curl_easy_setopt(curl,	CURLOPT_PROXY_SSL_CIPHER_LIST, "TLSv1");
	 ret = curl_easy_perform(curl);
	 curl_easy_cleanup(curl);
       }

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.
