bcrypt Blowfish password hashing py-bcrypt is an implementation the OpenBSD Blowfish password hashing algorithm, as described in "A Future-Adaptable Password Scheme" by Niels Provos and David Mazieres. This system hashes passwords using a version of Bruce Schneier's Blowfish block cipher with modifications designed to raise the cost of off-line password cracking. The computation cost of the algorithm is parametised, so it can be increased as computers get faster. Damien Miller 99ca6510db461a6772e1a620682472eb170727db 0.1
