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 or Schannel. OpenSSL (versions 0.9.3 and later), Secure Transport (on iOS 5 or later, or OS X 10.7 or later) and Schannel support "P12" for PKCS#12-encoded files.

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

DEFAULT
