.TH CURLOPT_SSL_VERIFYSTATUS 3 "04 Dec 2014" "libcurl 7.40.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_SSL_VERIFYSTATUS \- verify the certificate's status
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_VERIFYSTATUS, long verify);
.fi
.SH 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.
.SH DEFAULT
0
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
.SH EXAMPLE
.nf
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);
}
.fi
.SH AVAILABILITY
Added in 7.41.0. This option is currently only supported by the OpenSSL, GnuTLS
and NSS TLS backends.
.SH RETURN VALUE
Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise
returns CURLE_NOT_BUILT_IN.
