CURLOPT_SSL_VERIFYSTATUS(3)                           curl_easy_setopt options

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 OCSP 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.
