Bcrypt

This is an implementation of the OpenBSD Blowfish password hashing algorithm, as described in A Future-Adaptable Password Scheme by Niels Provos and David Mazieres. It's core is based on jBcrypt, but heavily refactored, modernized and with a lot of updates and enhancements. It supports all common versions, has a security sensitive API and is fully tested against a range of test vectors and reference implementations.
