.TH CURLOPT_CERTINFO 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_CERTINFO \- request SSL certificate information
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CERTINFO, long certinfo);
|
|
.SH DESCRIPTION
|
|
Pass a long set to 1 to enable libcurl's certificate chain info gatherer. With
|
|
this enabled, libcurl will extract lots of information and data about the
|
|
certificates in the certificate chain used in the SSL connection. This data
|
|
may then be retrieved after a transfer using \fIcurl_easy_getinfo(3)\fP and
|
|
its option \fICURLINFO_CERTINFO(3)\fP.
|
|
.SH DEFAULT
|
|
0
|
|
.SH PROTOCOLS
|
|
All TLS-based
