[Haskell-cafe] Password hashing

Hello, What library can be used to securely hash passwords? From what I understand, the "bcrypt" algorithm is what the experts recommend. It is described in the paper: http://www.openbsd.org/papers/bcrypt-paper.ps I couldn't find a haskell library for this. There is a BSD licensed C implementation that looks very simple here: http://www.mindrot.org/projects/py-bcrypt/ A translation to haskell should be straight forward. Alternatively, a haskell bcrypt library could directly use this implementation and provide a very light FFI wrapper. Any thoughts?
