Project description

bcrypt

Modern password hashing for your software and your servers

Installation

To install bcrypt, simply:

$ pip install bcrypt

Usage

Basic

Hashing and then later checking that a password matches the previous hashed password is very simple:

>>> import bcrypt
>>> password = b"super secret password"
>>> # Hash a password for the first time, with a randomly-generated salt
>>> hashed = bcrypt.hashpw(password, bcrypt.gensalt())
>>> # Check that a unhashed password matches one that has previously been
>>> #   hashed
>>> if bcrypt.hashpw(password, hashed) == hashed:
...     print("It Matches!")
... else:
...     print("It Does not Match :(")

Adjustable Work Factor

One of bcrypt’s features is an adjustable logarithmic work factor. To adjust the work factor merely pass the desired number of rounds to bcrypt.gensalt(rounds=12) which defaults to 12):

>>> import bcrypt
>>> password = b"super secret password"
>>> # Hash a password for the first time, with a certain number of rounds
>>> hashed = bcrypt.hashpw(password, bcrypt.gensalt(14))
>>> # Check that a unhashed password matches one that has previously been
>>> #   hashed
>>> if bcrypt.hashpw(password, hashed) == hashed:
...     print("It Matches!")
... else:
...     print("It Does not Match :(")

Compatibility

This library should be compatible with py-bcrypt and it will run on Python 2.6+, 3.2+, and PyPy.
