django-fernet-encrypted-fields 0.2.0

This is inspired by django-encrypted-fields.

Django Fernet Encrypted Fields

This package was created as a successor to django-encrypted-fields.

Getting Started

$ pip install django-fernet-encrypted-fields

In your settings.py, set random SALT_KEY

SALT_KEY = '0123456789abcdefghijklmnopqrstuvwxyz'

Then, in models.py

from encrypted_fields.fields import EncryptedTextField

class MyModel(models.Model):
    text_field = EncryptedTextField()

Use your model as normal and your data will be encrypted in the database.

Rotating SALT keys

You can rotate salt keys by turning the SALT_KEY settings.py entry into a list. The first key will be used to encrypt all new data, and decryption of existing values will be attempted with all given keys in order. This is useful for key rotation: place a new key at the head of the list for use with all new or changed data, but existing values encrypted with old keys will still be accessible

SALT_KEY = [
    'zyxwvutsrqponmlkjihgfedcba9876543210',
    '0123456789abcdefghijklmnopqrstuvwxyz'
]

If you wish to update the existing encrypted records simply load and re-save the models to use the new key.

for obj in MuModel.objects.all():
    obj.save()
