CURLOPT_PROXY_SSLKEYTYPE - set type of the proxy private key file

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLKEYTYPE, char *type);

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 format of your private key. Supported formats are "PEM", "DER" and "ENG".
