Introduction

Note: TEA Total hasn't been under active development for over a decade but I have decided to leave it up in case it is useful to anyone.

TEA Total is a very small 128 bit private key based encryption/decryption system which uses the block variant of TEA (Tiny Encryption Algorithm) by David Wheeler and Roger Needham of the Cambridge Computer Laboratory. TEA Total was written by Alex Holden. You can contact me at alex [at] alexholden [dot] net

TEA is said to be several times faster than DES, as well as being much smaller and possibly more secure. It also isn't encumbered by any patents and the reference implementation is in the public domain.

About TEA Total

Currently TEA Total only supports encryption and decryption of files (with optional compression and/or Base64 ASCII encoding). I am writing a set of TEA based encrypted tunnel programs which will allow you to wrap applications such that their input and output will be transparently forwarded over a network in encrypted form.

About the name: TEA Total is a play on the TEA encryption algorithm which is at the heart of the package, and the phrase "tee total"; a term used to refer to a person who does not drink alcohol. This is appropriate because I am tee total myself.

License

In the spirit of the TEA implementation itself, I have placed TEA Total in the public domain. You can do whatever you like with it, though I would prefer you to contribute any bug fixes back to me if possible.
