+
+This module provides a generic mixin to symmetrically encrypt data in the database
+while maintaining a standard Python workflow for developers.
+
+Odoo natively handles `password="True"` on views by sending plaintext data
+to the client, where the browser masks it. This module intercepts reads and writes
+to implement actual "data at rest" encryption using the `cryptography` library.

+
+Configuration
+=============
+
+To use this module, you need to configure a master encryption key in your
+``odoo.conf`` file:
+
+1. Generate a URL-safe base64-encoded 32-byte key. You have two options:
+
+   **Option A (Recommended - UI Wizard):**
+   - Log in as an Administrator (with "Settings" access).
+   - Go to Settings > Technical > Security > Generate Encryption Key (Fernet).
+   - Copy the generated key.
+
+   **Option B (Terminal):**
+   .. code-block:: python
+
+      from cryptography.fernet import Fernet
+      print(Fernet.generate_key().decode())
+
+2. Add the copied key to your configuration file under the ``[options]`` section:
+
+   .. code-block:: ini
+
+      [options]
+      encryption_key = <YOUR_GENERATED_KEY>
+
+3. Restart your Odoo server.
+
+If no key is configured, or the key is invalid, the module will log a warning
+and fallback to storing data in plaintext to prevent data loss.
+
+**WARNING:** The encryption key is NOT stored in the database. If you lose
+the key, all previously encrypted fields will become permanently unreadable.
+Keep your ``odoo.conf`` safe.
+
+Usage
+=====
+
+To use the encryption capabilities in your own custom models:
+
+1. Inherit the mixin in your model:
+
+   .. code-block:: python
+
+      class MyIntegration(models.Model):
+          _name = 'my.integration'
+          _inherit = ['encryption.mixin']
+
+          api_secret = fields.Char(string="API Secret", encrypted=True)
+
+2. In your XML view, use the native `password="True"` attribute so the frontend masks it:
+
+   .. code-block:: xml
+
+      <field name="api_secret" password="True" />
+
+Internal Python code can access `record.api_secret` normally and will receive the
+decrypted plaintext value. The web client will only receive `********`.
+
