NAME

CURLOPT_SSLCERTTYPE - specify type of the client SSL certificate  

SYNOPSIS

#include <curl/curl.h>

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

DESCRIPTION

Pass a pointer to a zero terminated string as parameter. The string should be the format of your certificate. 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"

CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
  curl_easy_setopt(curl, CURLOPT_SSLCERT, "client.pem");
  curl_easy_setopt(curl, CURLOPT_SSLCERTTYPE, "PEM");
  curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
  curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}
