How to Authenticate CryptoCard KT-1 Tokens using PHP

This page links to all the information I've collected about how to authenticate CryptoCard KT-1 tokens using PHP.

My usage of KT-1 tokens is a bit unconventional in that:

• It works best in my application to initialize the tokens on a Windows machine but to authenticate them on a Linux machine.  (Reason: the server that I use is about 100 miles away from the location from which it is used.)
• I'm using the AuthEngine product from CryptoCard (rather than a server product).  (AuthEngine is essentially a set of token initialization and authentication libraries for both Linux and Windows.)

There were several subtasks to complete:

• Programming CryptoCard KT-1 Tokens Using a Windows Platform.
• Securing Sensitive Data Between a PHP Script and the Compiled C Program that Authenticates the Token.
• Design of a Compiled C Program to Authenticate the KT-1 Token Using AuthEngine SDK.
• Calling the Compiled C Program From PHP and Processing the Results.
• Generating Random Numbers to Use as KT-1 Token AES-192 Keys From PHP.
• KT-1 Token Authentication and Resynchronization Demonstration Page.  (Source Code)
