CURLOPT_PROXY_SSL_VERIFYHOScurl_easy_setopt optCURLOPT_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.

       If verify value is set to 1:

       In  7.28.0  and	earlier:  treated as a debug option of some sorts, not
       supported anymore due to	frequently leading to programmer mistakes.

       From 7.28.1 to 7.65.3: setting it to 1 made  curl_easy_setopt()	return
       an error	and leaving the	flag untouched.

       From 7.66.0: treats 1 and 2 the same.

       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	signa-
       ture  of	 the  proxy  certificate.  If libcurl is built against NSS and
       CURLOPT_PROXY_SSL_VERIFYPEER(3)	is   zero,   CURLOPT_PROXY_SSL_VERIFY-
       HOST(3) is also set to zero and cannot be overridden.

DEFAULT
       2

PROTOCOLS
       All protocols when used over an 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.
