CURLOPT_DOH_SSL_VERIFYSTATUS3
Verify the doh ssl certificate's status
Usage
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_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 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.
Default
0
Protocols
DoH
Examples
int main(void)
{
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);
}
}
Return value
Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise returns CURLE_NOT_BUILT_IN.
