encrypted-text-field 0.1.0

A Django app providing a custom model field for storing sensitive information.

encrypted_text_field Django App

encrypted_text_field is a Django app providing a custom model field for storing sensitive information like passwords and API keys. The data is encrypted before being saved to the database and decrypted when accessed through Django's ORM in views or other business logic. The field will be rendered in Django's admin but ensures that values are not readable or displayed back in the UI, protecting sensitive information from exposure.

Features

• EncryptedTextField Model Field: Encrypt and decrypt data automatically.
• Security in Django Admin: Displays a password widget in the admin interface to edit fields without showing existing values.
• Generate Keys via Management Command: Includes a Django management command to generate new encryption keys.

Requirements

• Django 3.2 or newer
• Cryptography

Installation
