Hi, I'm Tony Arcieri. You may remember me from such software projects as Celluloid, Reia, and Cool.io... If you're already using bcrypt, relax, you're fine, probably. However, if you're looking for a key derivation function (or in bcrypt's case, password encryption function) for a new project, bcrypt is probably not the best one you can pick. In fact, there are two algorithms which are each better
