CURLOPT_PROXY_SSLCERTTYPE(3)                          curl_easy_setopt options

NAME
       CURLOPT_PROXY_SSLCERTTYPE - specify type of the proxy client SSL
       certificate

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Pass a pointer to a null-terminated string as parameter. The string
       should be the format of your client certificate used when connecting to
       an HTTPS proxy.

       Supported formats are "PEM" and "DER", except with Secure Transport.
       OpenSSL (versions 0.9.3 and later) and Secure Transport (on iOS 5 or
       later, or OS X 10.7 or later) also support "P12" for PKCS#12-encoded
       files.

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

DEFAULT
       "PEM"

PROTOCOLS
       All

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");

         curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT, "client.pem");
