Yes that's right. The PasswordHashingFFI stuff is all one way encryption.<br>
Blowfish is two way, and the current implementation only works for 8 byte<br>
chunks. I stopped working on it when the Smalltalk bcrypt implementation I<br>
wanted proved to be 5000x times slower than the FFI version. Someone needs<br>
to add the CBC part to Blowfish to encrypt longer strings. I do not know of<br>
another in image two way encryption scheme, but there may be something in<br>
the Cryptography repo. I'm not sure.<br>
