Hi Mariano,

Hash functions are one way
(http://en.wikipedia.org/wiki/Cryptographic_hash_function) that's because
usually you don't want someone can decrypt password.

Cheers

Hi Paul, and just to be sure I understand...none of them could work as a
two-way encryption, right?
The only one is your Pharo's version of Blowfish but that only works with
8

Thanks!
