CURLOPT_DOH_SSL_VERIFYSTATUS 3 "11 Feb 2021" "libcurl 7.76.0" "curl_easy_setopt options"
NAME
CURLOPT_DOH_SSL_VERIFYSTATUS - verify the DoH SSL certificate's status
SYNOPSIS
#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.
Note that if this option is enabled but the server does not support the TLS
extension, the verification will fail.
DEFAULT
0
PROTOCOLS
DoH
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
curl_easy_setopt(curl, CURLOPT_DOH_URL, "https://cloudflare-dns.com/dns-query");
/* Ask for OCSP stapling when verifying the DoH server */
curl_easy_setopt(curl, CURLOPT_DOH_SSL_VERIFYSTATUS, 1L);
curl_easy_perform(curl);
}
AVAILABILITY
Added in 7.76.0. 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, otherwise
returns CURLE_NOT_BUILT_IN.
