curl_easy_setopt options 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, oth- erwise returns CURLE_NOT_BUILT_IN.
