Passlib 1.7.1 documentation

Welcome

Passlib is a password hashing library for Python 2 & 3, which provides cross-platform implementations of over 30 password hashing algorithms, as well as a framework for managing existing password hashes. It’s designed to be useful for a wide range of tasks, from verifying a hash found in /etc/shadow, to providing full-strength password hashing for multi-user application.

As a quick sample, the following code hashes and then verifies a password using the PBKDF2-SHA256 algorithm:

>>> # import the hash algorithm
>>> from passlib.hash import pbkdf2_sha256

>>> # generate new salt, and hash a password
>>> hash = pbkdf2_sha256.hash("toomanysecrets")
>>> hash
'$pbkdf2-sha256$29000$N2YMIWQsBWBMae09x1jrPQ$1t8iyB2A.WF/Z5JZv.lfCIhXXN33N23OSgQYThBYRfk'

>>> # verifying the password
>>> pbkdf2_sha256.verify("toomanysecrets", hash)
True
>>> pbkdf2_sha256.verify("joshua", hash)
False
