# CURLOPT\_DOH\_SSL\_VERIFYSTATUS(3)

verify the DoH SSL certificate's status

## 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)](/CURLOPT_SSL_VERIFYSTATUS/3.md)* 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

## EXAMPLE

```
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);
  }
}
```

## AVAILABILITY

Added in 7.76.0. This option is currently only supported by the OpenSSL, and GnuTLS TLS backends.

## RETURN VALUE

Returns CURLE\_OK if OCSP stapling is supported by the SSL backend, otherwise returns CURLE\_NOT\_BUILT\_IN.
