Create Egypt ITIDA CAdES-BES .p7s Signature (File to File)

Demonstrates how to create a .p7s signature that fits Egypt's ITIDA requirements. Chilkat2 PHP

<?php

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

$crypt = new Crypt2();

$cert = new Cert();

// There are many ways to load the certificate.
// This example was created for a customer using an ePass2003 USB token.
// Assuming the USB token is the only source of a hardware-based private key..
