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 zero 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"
