CURLOPT_SSL_VERIFYSTATUS3
Verify the certificate's status
Usage
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_VERIFYSTATUS, long verify);
Overview
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
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
Examples
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);
}
}
Return value
Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise returns CURLE_NOT_BUILT_IN.
