CURLOPT_PROXY_SSL_OPTIONS(3)				     curl_easy_setopt options				      CURLOPT_PROXY_SSL_OPTIONS(3)

NAME

       CURLOPT_PROXY_SSL_OPTIONS - set proxy SSL behavior options

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_OPTIONS, long bitmask);

DESCRIPTION

       Pass a long with a bitmask to tell libcurl about specific SSL behaviors.

       CURLSSLOPT_ALLOW_BEAST  tells  libcurl to not attempt to use any workarounds for a security flaw in the SSL3 and TLS1.0 protocols.  If this
       option isn't used or this bit is set to 0, the SSL layer libcurl uses may use a work-around for this flaw although it might cause  interop-
       erability  problems  with  some	(older)  SSL implementations. WARNING: avoiding this work-around lessens the security, and by setting this
       option to 1 you ask for exactly that.  This option is only supported for DarwinSSL, NSS and OpenSSL.

       CURLSSLOPT_NO_REVOKE tells libcurl to disable certificate revocation checks for those SSL backends where such  behavior	is  present.  Cur-
       rently  this option is only supported for WinSSL (the native Windows SSL library), with an exception in the case of Windows' Untrusted Pub-
       lishers blacklist which it seems can't be bypassed. This option may have broader support to accommodate other SSL backends in  the  future.

CURLOPT_PROXY_SSL_VERIFYHOST(3) 			     curl_easy_setopt options				   CURLOPT_PROXY_SSL_VERIFYHOST(3)

NAME

       CURLOPT_PROXY_SSL_VERIFYHOST - verify the proxy certificate's name against host

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_VERIFYHOST, long verify);

DESCRIPTION

       Pass a long set to 2L as asking curl to verify in the HTTPS proxy's certificate name fields against the proxy name.

       This option determines whether libcurl verifies that the proxy cert contains the correct name for the name it is known as.

       When  CURLOPT_PROXY_SSL_VERIFYHOST(3)  is 2, the proxy certificate must indicate that the server is the proxy to which you meant to connect
       to, or the connection fails.

       Curl considers the proxy the intended one when the Common Name field or a Subject Alternate Name field in the certificate matches the  host
       name in the proxy string which you told curl to use.

       When the verify value is 1L, curl_easy_setopt will return an error and the option value will not be changed due to old legacy reasons.

       When the verify value is 0L, the connection succeeds regardless of the names used in the certificate. Use that ability with caution!

       See  also  CURLOPT_PROXY_SSL_VERIFYPEER(3)  to  verify the digital signature of the proxy certificate.  If libcurl is built against NSS and
       CURLOPT_PROXY_SSL_VERIFYPEER(3) is zero, CURLOPT_PROXY_SSL_VERIFYHOST(3) is also set to zero and cannot be overridden.

DEFAULT

       2

PROTOCOLS

       All protocols when used over a HTTPS proxy.

EXAMPLE

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

	 /* Set the default value: strict name check please */
	 curl_easy_setopt(curl, CURLOPT_PROXY_SSL_VERIFYHOST, 2L);

	 curl_easy_perform(curl);
       }

AVAILABILITY

       Added in 7.52.0.

       If built TLS enabled.

RETURN VALUE

       Returns CURLE_OK if TLS is supported, and CURLE_UNKNOWN_OPTION if not.

       If 1 is set as argument, CURLE_BAD_FUNCTION_ARGUMENT is returned.
