| 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` | |
| The result is a random and safely hidden `SECRET_KEY`. | |
