You need enable https:// in your php.ini file:
- extension=php_openssl.dll (uncomment it)
- allow_url_include = On (change to on)
then try again with cURL using following parameters:
- curl_setopt($ch, CURLOPT_SSLCERT, "example.p12");
- curl_setopt($ch, CURLOPT_SSLCERTTYPE, "P12");
- curl_setopt($ch, CURLOPT_SSLKEYPASSWD, "password here");
