NAME

       CURLOPT_PROXY_SSLCERTTYPE - 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"
