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 chars long. Is it like this? Or is there any other two-way encryption?
Thanks!

Yes that's right. The PasswordHashingFFI stuff is all one way encryption. Blowfish is two way, and the current implementation only works for 8 byte chunks. I stopped working on it when the Smalltalk bcrypt implementation I wanted proved to be 5000x times slower than the FFI version. Someone needs to add the CBC part to Blowfish to encrypt longer strings. I do not know of another in image two way encryption scheme, but there may be something in the Cryptography repo. I'm not sure.
Hi Paul, Sorry for the cross posting. I was using the Smalltalk version of the Blowfish you did to encrypt and decrypt things. But now I realize it is very very slow for the usage I need. You seem to have faced the same problem. I am encrypting pieces of 8 characters long. But I wonder if the *decryption* is available as well in FFI version? I see #ffiCrypt:with: but nothing to decrypt... Thanks in advance -- Mariano http://marianopeck.wordpress.com
