Created August 24, 2012 17:01
Generating a properly secure SECRET_KEY in Django
"""
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`
