PCI-compliant authentication application for Django 1.4+. Uses "best of" existing libraries then fills in the gaps.

Project description

django-pci-auth

Django 1.4+ only

This library integrates the current Django “best of” PCI auth libraries into a single application then fills in the gaps. Filling in the gaps involves making decisions for you e.g.:

And adding additional functionality e.g.:

  • Database models to persist event data e.g. lockouts (See: docs/MODELS.rst).

  • Additional recently_used validator for django-passwords.

Features

  • Stronger password hashing that allows for selection of hashing algorithm scrypt, bcrypt, PBKDF2, etc. via settings.py. [1]

  • Checking for strong passwords with a default length setting overrideable in settings.py. [2]

  • Integrate strong passwords into Django Admin.

  • Lock out account for n minutes after x failed log-in attempts. [3]

  • Set inactivity timeouts.

  • Generate event/email when lock-out occurs.

  • Set flags disallowing certain accounts to be locked out.

  • Log every log-on and explicit log-out (not necessary to log timed out log-ins).

  • Track last four passwords and do not allow re-use.

  • Force password reset after X amount of time.

  • Provide JavaScript to check for strong passwords inline.

Installation

Stronger password hashing

This is a built-in feature in Django 1.4+. Documented here for convenience:

PASSWORD_HASHERS = (
    # From https://docs.djangoproject.com/en/1.4/topics/auth/:
    # "[redacted] This means that Django will use the first hash in the list
    # to store all passwords, but will support checking passwords stored with
    # the rest of the hashes in the list. If you remove a hash from the list
    # it will no longer be supported.
    'django.contrib.auth.hashers.PBKDF2PasswordHasher',
    'django.contrib.auth.hashers.PBKDF2SHA1PasswordHasher',
    'django.contrib.auth.hashers.BCryptPasswordHasher',
    'django.contrib.auth.hashers.SHA1PasswordHasher',
    'django.contrib.auth.hashers.MD5PasswordHasher',
    'django.contrib.auth.hashers.CryptPasswordHasher',
)

Password Reuse

How many old passwords will you store? This feature will prevent users from using the same passwords over and over again; it will keep the last OLD_PASSWORD_STORAGE_NUM number of passwords around and remove anything older. E.g.:

OLD_PASSWORD_STORAGE_NUM = 4
