CURLOPT_PROXY_SSLKEYTYPE(3)                           curl_easy_setopt options

NAME
       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 an HTTPS proxy, not an HTTPS server.

       Pass a pointer to a null-terminated string as parameter. The string
       should be the format of your private key. Supported formats are "PEM",
       "DER" and "ENG".

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

PROTOCOLS

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
         curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT, "client.pem");
         curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem");
