Passlib 1.6.4 documentation¶
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 SHA256-Crypt algorithm:
>>> # import the hash algorithm >>> from passlib.hash import sha256_crypt >>> # generate new salt, and hash a password >>> hash = sha256_crypt.encrypt("toomanysecrets") >>> hash '$5$rounds=80000$zvpXD3gCkrt7tw.1$QqeTSolNHEfgryc5oMgiq1o8qCEAcmye3FoMSuvgToC' >>> # verifying the password >>> sha256_crypt.verify("toomanysecrets", hash) True >>> sha256_crypt.verify("joshua", hash) False
Password Hashing Algorithms¶
- provides the
CryptContextclass, a flexible container for managing and migrating between multiple hash algorithms.
- predefined CryptContext objects for managing the hashes used by MySQL, PostgreSQL, OpenLDAP, and others applications.
- predefined CryptContext objects for managing the hashes found in Linux & BSD “shadow” files.
