CURLOPT_SSL_VERIFYSTATUS(3)                           Library Functions Manual


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).
