CURLOPT_SSL_VERIFYSTATUS(3)curl_easy_setopt optionsCURLOPT_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.
