SpecShaper Encrypt Bundle

A bundle to handle encoding and decoding of parameters using OpenSSL and Doctrine lifecycle events.

Features include:

• V4 is will be Symfony 7 PHP 8.2
• V3 is Symfony 5.4|6 PHP 8. I'm moving my projects to symfony 7 so will not maintain after this v3.2.
• V2 is Symfony 5 not maintained.
• v1 is Symfony 3.4 not maintained.
• Uses OpenSSL
• Uses Lifecycle events

Features road map:

• [x] Create a factory method to expand for different encryptors
• [x] Create a twig function to decrypt encoded values
• [x] Expand parameters to allow selection of encoding method
• [x] Create CLI commands to encrypt and decrypt the entire database
• [ ] Handle DateTime data types via the bundle.

About

EncryptBundle has been written for the Parolla Plugins and Parolla websites to encode users private data. The bundle is expanded in a larger gdpr-bundle.

Reporting an issue or a feature request

Issues and feature requests are tracked in the Github issue tracker.

When reporting a bug, it may be a good idea to reproduce it in a basic project built using the Symfony Standard Edition to allow developers of the bundle to reproduce the issue by simply cloning it and following some steps.

Installation

Step 1: Install from package

Open a command console, enter your project directory and execute the following command to download the latest development version of this bundle:

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the bundle

The receipe will create a package config file under config/packages/spec_shaper_encrypt.yaml.

If required, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

Step 2: Configure the bundle

Generate a 256-bit key using the command provided in the bundle.

Copy the key into your .env file.

Maker will have created a packages yaml file. The key is resolved in there.

You can disable encryption by setting the 'is_disabled' option to true. Decryption still continues if any values contain the \ suffix.

You can extend the EncryptBundle default Subscriber and override its methods. Use the 'subscriber_class' option to point the bundle at your custom subscriber.

If you want to define your own annotation/attribute, then this can be used to trigger encryption by adding the annotation class name to the 'annotation_classes' option array.

You can pass the class name of your own encyptor service using the optional encryptorClass option.

Alternative EncryptKeyEvent

The EncryptKey can be set via a dispatched event listener, which overrides any .env or param.yml defined key. Create a listener for the EncryptKeyEvents::LOAD_KEY event and set your encryption key at that point.

Step 3: Create the entities

Add the Encrypted attribute class within the entity.

Add the attribute #[Encrypted] to the properties you want encrypted.

Note that the legacy annotation '@Encrypted' in the parameters is deprecated and will be discontinued in the next major update.

Where encrypting a field you will need to set the column type as string.

Your getters and setters may also need to be type declared.

For example, boolean should either be return declared bool, or return a bool using a ternary method.

For DateTime parameters store the date as a string, and use the getters and setters to convert that string.

You may also need to create a DataTransformer if you are using the parameter in a form with the DateType form type.

Step 4: General Use

The bundle comes with an DoctrineEncryptSubscriber. This subscriber catches the doctrine events onLoad, onFlush and postFlush.

The onLoad event subscriber will decrypt your entity parameter at loading. This means that your forms and form fields will already be decrypted.

The onFlush and postFlush event subscribers will check if encryption is enabled, and encrypt the data before entry to the database.

So, in normal CRUD operation you do not need to do anything in the controller for encrypting or decrypting the data.

Step 5: Decrypt in services and controllers

You can of course inject the EncryptorInterface service any time into classes either by using autowiring or defining the injection in your service definitions.

Or you can dispatch the EncryptEvent.

Step 5: Decrypt in templates

If you query a repository using a select with an array result then the doctrine onLoad event subscriber will not decrypt any encrypted values.

In this case, use the twig filter to decrypt your value when rendering.

Commands

You have already seen the command to generate a encryption key:

You can decrypt/encrypt the entire database using the following

The requried argument should be be decrypt or encrypt.

There is an option to define the database connection if you employ multiple connections in your application.
