Fernet symmetric encryption for Django model fields, using the cryptography library.
django-fernet-fields supports Django 1.8.2 and later on Python 2.7, 3.3, 3.4, pypy, and pypy3.
PostgreSQL is fully supported; SQLite is supported except for indexing and unique constraints on encrypted fields. Support for other database backends could easily be added (though indexing support is only possible on databases that support indexes on expressions).
Documentation for django-fernet-fields is available at https://django-fernet-fields.readthedocs.org/
This app is available on PyPI and can be installed with pip install django-fernet-fields.
