A backport of the password validation system from Django 1.9 (by Erik Romijn), for use on earlier Django versions.
Password validation isn't hard to implement yourself, but if you use this backport you'll be writing your validators to the same API that will be built-in to upcoming Django versions.
django-password-validation supports Django 1.8.2 and later on Python
2.7, 3.3, 3.4, pypy, and pypy3.
Documentation for django-password-validation is available at https://django-password-validation.readthedocs.org/
This app is available on PyPI and can be installed with pip install
django-password-validation.
