Hi!

Here is a TEA (Tiny Encryption Algorithm) implementations for the flat assembler (both assembly and run time versions). Also, a XXTEA (TEA extension) included.

The code seems a dirty, but you can free optimize it.

Enjoy.

Thanks for the submission.

BTW: it crashes on my Pentium. The code uses MMX but does not check first that MMX is available. Later I'll test it on my Pentium-M.

Yes, XXTEA code uses MMX registers for improving perfomance. It can be replaced via memory variables, of course.
