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 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".

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

PROTOCOLS

       Used with HTTPS proxy

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");
         curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEYTYPE, "PEM");
         curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }
