CURLOPT_PROXY_SSLVERSION(3)				     curl_easy_setopt options				       CURLOPT_PROXY_SSLVERSION(3)

NAME

       CURLOPT_PROXY_SSLVERSION - set preferred proxy TLS/SSL version

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLVERSION, long version);

DESCRIPTION

       Pass a long as parameter to control which version of SSL/TLS to attempt to use when connecting to an HTTPS proxy.

       Use one of the available defines for this purpose. The available options are:

	      CURL_SSLVERSION_DEFAULT
		     The default action. This will attempt to figure out the remote SSL protocol version.

	      CURL_SSLVERSION_TLSv1
		     TLSv1.x

	      CURL_SSLVERSION_TLSv1_0
		     TLSv1.0

	      CURL_SSLVERSION_TLSv1_1
		     TLSv1.1

	      CURL_SSLVERSION_TLSv1_2
		     TLSv1.2

	      CURL_SSLVERSION_TLSv1_3
		     TLSv1.3

	      CURL_SSLVERSION_MAX_DEFAULT
		     The  flag	defines  maximum  supported  TLS  version as TLSv1.2 or default value from SSL library. Only library NSS currently
		     allows to get maximum supported TLS version.  (Added in 7.54.0)

	      CURL_SSLVERSION_MAX_TLSv1_0
		     The flag defines maximum supported TLS version as TLSv1.0.  (Added in 7.54.0)

	      CURL_SSLVERSION_MAX_TLSv1_1
		     The flag defines maximum supported TLS version as TLSv1.1.  (Added in 7.54.0)

	      CURL_SSLVERSION_MAX_TLSv1_2
		     The flag defines maximum supported TLS version as TLSv1.2.  (Added in 7.54.0)

	      CURL_SSLVERSION_MAX_TLSv1_3
		     The flag defines maximum supported TLS version as TLSv1.3.  (Added in 7.54.0)

DEFAULT

       CURL_SSLVERSION_DEFAULT

PROTOCOLS

       All

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

	 /* ask libcurl to use TLS version 1.0 or later */
	 curl_easy_setopt(curl, CURLOPT_PROXY_SSLVERSION, CURL_SSLVERSION_TLSv1_1 |
			  CURL_SSLVERSION_MAX_DEFAULT);

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY

       Added in 7.52.0

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.

CURLOPT_PROXY_SSL_CIPHER_LIST(3)			     curl_easy_setopt options				  CURLOPT_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 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://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.fedorahosted.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.
