Himitsu

Introduction

Himitsu is a wrapper for crypt_blowfish that provides Bcrypt hashing.

The C module and most of the code in the Bcrypt class is taken from cryptacular with Daniel Holth's permission.

Installation

Download Himitsu from Github and run the following command. Keep in mind that Himitsu has only been tested with Python 2.7 and 3.2.

python setup.py install

Or from PyPi:

pip install himitsu

And you're done.

Usage

Example:

import himitsu

b = himitsu.Bcrypt()

Create a hash:

h = b.encode('password')

Make sure a hash is valid:

print b.valid(h)

Check a hash (validity of hash is also checked):

print b.check(h, 'password')
