CURLOPT_PROXY_SSLCERT explained

NAME

CURLOPT_PROXY_SSLCERT - set SSL proxy client certificate

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT, char *cert);

DESCRIPTION

This option is for connecting to a HTTPS proxy, not a HTTPS server.

Pass a pointer to a zero terminated string as parameter. The string should be the file name of your client certificate used to connect to the HTTPS proxy. The default format is "P12" on Secure Transport and "PEM" on other engines, and can be changed with CURLOPT_PROXY_SSLCERTTYPE.

With NSS or Secure Transport, this can also be the nickname of the certificate you wish to authenticate with as it is named in the security database. If you want to use a file from the current directory, please precede it with "./" prefix, in order to avoid confusion with a nickname.

When using a client certificate, you most likely also need to provide a private key with CURLOPT_PROXY_SSLKEY.

The application does not have to keep the string around after setting this option.

NULL
