.SH NAME
|
|
CURLOPT_DOH_SSL_VERIFYSTATUS \- verify the DoH SSL certificate\(aqs status
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_SSL_VERIFYSTATUS,
|
|
long verify);
|
|
.fi
|
|
.SH 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 \fICURLOPT_SSL_VERIFYSTATUS(3)\fP 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.
|
|
.SH DEFAULT
|
|
0
|
|
.SH PROTOCOLS
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
|
|
This option works only with the following TLS backends:
|
|
GnuTLS and OpenSSL
|
|
.SH EXAMPLE
|
|
.nf
|
|
int main(void)
|

|
|
|
|
curl_easy_setopt(curl, CURLOPT_DOH_URL,
|
|
"https://cloudflare-dns.com/dns-query");
|

/* Ask for OCSP stapling when verifying the DoH server */
|
|
