django-fernet-fields-v2

What it is and what it does

django-fernet-fields-v2 is a Django app that adds encrypted model fields using Fernet symmetric encryption from the cryptography library. It lets you mark sensitive fields for automatic encryption at rest in the database, so plaintext never touches disk. The package wraps Django's BinaryField and handles encryption and decryption transparently on read and write.

It is a fork updated to support Django 4. The package is tested against PostgreSQL, SQLite, and MySQL, though any Django backend supporting BinaryField should work. It requires Django >=3.2 and Python >=3.8, but has not been maintained since August 2023.

Use it for:

• Encrypt user passwords, API keys, or authentication tokens in a Django model without application-level encryption logic.
• Store personally identifiable information encrypted at rest in PostgreSQL, SQLite, or MySQL databases.
• Add field-level encryption to an existing Django project with minimal code changes.
• Comply with data protection regulations by encrypting sensitive fields before they reach the database.
• Protect against database breaches by ensuring stolen backups contain only ciphertext, not plaintext secrets.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides Fernet symmetric encryption for Django model fields, allowing you to encrypt sensitive data at the database level using the cryptography library.

Yes, if you need field-level encryption in Django and accept the maintenance risk. The package is abandoned (last update August 2023), so it will not receive security patches or compatibility fixes for newer Django or Python versions. Install only if your Django and Python versions are locked to those it was tested on, or if you are willing to fork and maintain it yourself.

Install

django-fernet-fields-v2 on PyPI

pip install django-fernet-fields-v2

uv add django-fernet-fields-v2

poetry add django-fernet-fields-v2

Installing django-fernet-fields-v2

Before you install

Low friction install with only Django and cryptography as runtime dependencies. However, the package is abandoned—last release was 2023-08-15 and no commits since then. Use only if you accept that security or compatibility updates will not arrive.

License in practice

Licensed under MIT (permissive), so you can use, modify, and distribute freely with minimal restrictions.

Quickstart

pip install django-fernet-fields-v2

from django_fernet_fields_v2 import EncryptedTextField

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

Requires Django >=3.2 and Python >=3.8; only PostgreSQL, SQLite, and MySQL are tested.

Verify before relying

• Whether the package works with Django versions released after 2023-08-15.
• Current compatibility with Python versions beyond 3.11.
• Whether cryptography library updates since last release affect encryption/decryption.
• Whether any Django database backends other than PostgreSQL, SQLite, and MySQL work with BinaryField support.
