# NAME
|
||
|
|
|
||
|
|
CURLOPT_SSL_VERIFYSTATUS - verify the certificate's status
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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 fails.
|
||
|
|
|
||
|
|
# DEFAULT
|
||
|
|
|
||
|
|
0
|
||
|
|
|
||
|
|
# PROTOCOLS
|
||
|
|
|
||
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
||
|

|

# EXAMPLE
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
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);
|

|
|
GnuTLS TLS backends.
|
||
|
|
|
||
|
|
# RETURN VALUE
|
||
|
|
|
||
|
|
Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise
|
||
|
|
returns CURLE_NOT_BUILT_IN.
