How to put up an Adobe Air Flex 3 encryption system

This tutorial series shows you how to put up an Adobe Air Flex 3 Encryption System. One of the weak points of Adobe AIR and Flex is there is no encryption system built in, making your data and applications vulnerable. But that's ok, because this tutorial will show you how to remedy the problem by adding an AES encryption system.
In part 1, Mike Lively of Northern Kentucky University discusses the AES (Advanced Encryption Standard) encryption system and show where to download the actionscript 3 encryption classes and how to get them running in Adobe Flex.
Part 2: demonstrate how to decouple the tab keys from the encrypt and decrypt source code so the code can be used for more advanced applications.
