f_TEA is a 128-bit encryption system based on the TEA algorithm by Roger Needham and David Wheeler for Flash and PHP. The current version (0.01 pre-alpha) is a pre-release intended for developers only. You can download it from: SourceForge.net

The f_TEA class does not encrypt your SWF file. Rather it encrypts data coming and going to/from your Flash application similar to SSL. It may be used for both online and offline applications on any human-readable format such as plain text, XML, HTML, and so on. This initial version is intended for testing and review purposes and is not integrated with its PHP counterpart. Future revisions will include secure key exchange mechanisms, full integration, and larger data capacity.

f_TEA is the first in the BNM Foundation Classes series targetted at developers for building robust, secure, portable Flash applications.
