CURLOPT_PROXY_SSL_VERIFYHOST 3 "December 16, 2016" "libcurl 7.58.0" "curl_easy_setopt options"
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.
