NAME

       CURLOPT_SSL_VERIFYSTATUS - verify the certificate's status

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       Pass a long as parameter set to 1 to enable or 0 to disable.

       This  option  determines  whether libcurl verifies the status of the server cert using the
       "Certificate Status Request" TLS extension (aka. OCSP stapling).

       Note that if this option is enabled but the server does not support the TLS extension, the
       verification will fail.

DEFAULT

       0

PROTOCOLS

       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         /* ask for OSCP stapling! */
         curl_easy_setopt(curl, CURLOPT_SSL_VERIFYSTATUS, 1L);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY

       Added  in  7.41.0.  This option is currently only supported by the OpenSSL, GnuTLS and NSS
       TLS backends.

RETURN VALUE

       Returns CURLE_OK if OCSP stapling is supported  by  the  SSL  backend,  otherwise  returns
       CURLE_NOT_BUILT_IN.
