Demonstrates how to use a certificate that has already been installed on a Windows PC for TLS client authentication. PHP Extension

<?php

include("chilkat.php");

$success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$http = new CkHttp();

// On Windows, a pre-installed certificate can be loaded in a number of different ways.
// This example loads by the common name:
$cert = new CkCert();
$success = $cert->LoadByCommonName('My ECA Medium Assurance Identity Certificate');
if ($success != true) {
    print $cert->lastErrorText() . "\n";
    exit;
}

// Make sure this certificate has a private key available.  
// It should be a private key such that when the certificate was installed, it was marked as "exportable"
// so that authorized programs are able to access the private key.
if ($cert->HasPrivateKey() != true) {
    print 'A private key is needed for TLS client authentication.' . "\n";
    print 'This certificate has no private key.' . "\n";
    exit;
}

// Set the certificate to be used for mutual TLS authentication
// (i.e. sets the client-side certificate for two-way TLS authentication)
$success = $http->SetSslClientCert($cert);
if ($success != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

// At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
// connection will automatically use it if the server demands a client-side cert.
