# NAME
|
||
|
|
|
||
|
|
CURLOPT_DOH_SSL_VERIFYSTATUS - verify the DoH SSL certificate's status
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_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 DoH
|
||
|
|
(DNS-over-HTTPS) server cert using the "Certificate Status Request" TLS
|
||
|
|
extension (aka. OCSP stapling).
|
||
|
|
|
||
|
|
This option is the DoH equivalent of CURLOPT_SSL_VERIFYSTATUS(3) and
|
||
|
|
only affects requests to the DoH server.
|
||
|
|
|
||
|
|
If this option is enabled and the server does not support the TLS extension,
|
||
|
|
the verification fails.

# AVAILABILITY

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