CURLOPT_SSL_VERIFYSTATUS(3)         libcurl        CURLOPT_SSL_VERIFYSTATUS(3)


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.
