Strong, Simple, and Precise security for Flask APIs

API security should be strong, simple, and precise like a Roman Legionary. This package aims to provide that. Using JWT tokens as implemented by PyJWT, flask_praetorian uses a very simple interface to make sure that the users accessing your API’s endpoints are provisioned with the correct roles for access.

This project was heavily influenced by Flask-Security, but intends to supply only essential functionality. Instead of trying to anticipate the needs of all users, flask-praetorian will provide a simple and secure mechanism to provide security for APIs specifically.

The flask-praetorian package can be used to:

• Encrypt (hash) passwords for storing in your database

• Verify plaintext passwords against the encrypted, stored versions

• Generate authorization tokens upon verification of passwords

• Check requests to secured endpoints for authorized tokens

• Ensure that the users associated with tokens have necessary roles for access

• Parse user information from request headers for use in client route handlers

All of this is provided in a very simple to confiure and initialize flask extension. Though simple, the security provided by flask-praetorian is strong due to the usage of the proven security technology of JWT and python’s PassLib package.
