Bcrypt is an implementation of a modern password hashing algorithm, based on the Blowfish block cipher, by Niels Provos and David Mazieres. It has been the default password scheme since OpenBSD 2.1.

A paper on the algorithm that explains its design decisions is available here:

The most important property of bcrypt is that it is adaptable to future processor performance improvements, allowing you to arbitrarily increase the processing cost of checking a password while still maintaining compatibility with your older password hashes.

This package provides a high level object oriented wrapper around bcrypt, as well as low level bindings to the C library. It uses the random number generator random.SystemRandom() to create the salts.


To build the module from source code, read documentation on doc/source.txt.


Yamlog manages the error catching code and error reporting. Read its documentation if want to be set up.


Typical usage:

import bcryptor

hasher = bcryptor.Bcrypt()
hash = hasher.create('crack my pass')

And to validate:

>>> hasher.valid('crack my pass', hash)
>>> hasher.valid('Crack my pass', hash)
