.TH CURLOPT_DOH_SSL_VERIFYSTATUS 3 "11 Feb 2021" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_DOH_SSL_VERIFYSTATUS \- verify the DoH SSL certificate's 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
