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
       fails.

DEFAULT

       0

PROTOCOLS

       This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

       This option works only with the following TLS backends: GnuTLS and OpenSSL

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           /* ask for OCSP stapling */
           curl_easy_setopt(curl, CURLOPT_SSL_VERIFYSTATUS, 1L);
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       Added in curl 7.41.0

RETURN VALUE

       curl_easy_setopt(3) returns a CURLcode indicating success or error.

       CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
