bolshoibooze / secret-key-gen.py
Created May 31, 2014 15:26 — forked from ndarville/secret-key-gen.py
"""
Two things are wrong with Django's default `SECRET_KEY` system:
1. It is not random but pseudo-random
2. It saves and displays the SECRET_KEY in `settings.py`
This snippet
1. uses `SystemRandom()` instead to generate a random key
2. saves a local `secret.txt`
