.TH CURLOPT_PROXY_SSL_VERIFYHOST 3 "16 Nov 2016" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_PROXY_SSL_VERIFYHOST \- verify the proxy certificate's name against host
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_VERIFYHOST,
|
|
long verify);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long set to 2L as asking curl to \fIverify\fP in the HTTPS proxy's
|
|
certificate name fields against the proxy name.
|
|
|
|
This option determines whether libcurl verifies that the proxy cert contains
|
|
the correct name for the name it is known as.
|
|
|
|
When \fICURLOPT_PROXY_SSL_VERIFYHOST(3)\fP is 2, the proxy certificate must
|
|
indicate that the server is the proxy to which you meant to connect to, or the
|
|
connection fails.
|
|
|
|
Curl considers the proxy the intended one when the Common Name field or a
|
|
Subject Alternate Name field in the certificate matches the host name in the
|
|
proxy string which you told curl to use.
|
|
|
|
If \fIverify\fP value is set to 1:
|
|
|
|
In 7.28.0 and earlier: treated as a debug option of some sorts, not supported
|
|
anymore due to frequently leading to programmer mistakes.
|
|
|
|
From 7.28.1 to 7.65.3: setting it to 1 made \fIcurl_easy_setopt(3)\fP return
|
|
an error and leaving the flag untouched.
|
|
|
|
From 7.66.0: treats 1 and 2 the same.
|
|
|
|
When the \fIverify\fP value is 0L, the connection succeeds regardless of the
|
|
names used in the certificate. Use that ability with caution!
|
|
|
|
See also \fICURLOPT_PROXY_SSL_VERIFYPEER(3)\fP to verify the digital signature
|
|
of the proxy certificate.
|
|
.SH DEFAULT
|
|
2
|
|
.SH PROTOCOLS
|
|
All protocols when used over an HTTPS proxy.
