[TEA]

Eh?. I haven´t seen anything about that. Only the more "strong" version
in the same home site.

The search "tea and cryptoana*" in Altavista gives 7 matches, not
related.

Do you have any reference?.

Why not?. I need a *simple*, *lightning* fast crypt, without setup
overhead. Streng is important but only for "domestic" attacks, since
each register is crypted using its unique "user provided but server
generated" key. In fact we are using only 64 bit keys, with up-most 64
bits set to 0. The users already have a hard time remembering 12 random
chars (64 bits coded as two 32 bit base64).

Speed and simplicity.
