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 a 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"
