# Laravel 5.5+ Database Encryption Package ![laravel-database-encryption banner from the documentation](docs/img/banner-1544x500.png?raw=true) [![License](]( [![Current Release](]( [![Total Downloads](]( [![Build Status](]( [![Dependency Status](]( [![Scrutinizer CI](]( [![StyleCI](]( [![Maintainability](]( [![Test Coverage](]( ## A package for automatically encrypting and decrypting Eloquent attributes in Laravel 5.5+, based on configuration settings. The purpose of this project is to create a set-it-and-forget-it package that can be installed without much effort to encrypt and decrypt Eloquent model attributes stored in your database tables, transparently. It is therefore highly opinionated but built for configuration. When enabled, it automagically begins encrypting data as it is stored in the model attributes and decrypting data as it is recalled from the model attributes. All data that is encrypted is prefixed with a header so that encrypted data can be easily identified, encryption keys rotated, and (optionally) versioning of the encrypted data format itself. This supports columns that store either encrypted or non-encrypted data to make migration easier. Data can be read from columns correctly regardless of whether it is encrypted or not but will be automatically encrypted when it is saved back into those columns. Standard Laravel Eloquent features like attribute casting will continue to work as normal, even if the underlying values stored in the database are encrypted by this package. There is [documentation for `laravel-database-encryption` online](, the source of which is in the [`docs/`]( directory. The most logical place to start are the [docs for the `HasEncryptedAttributes` trait]( ## Table of Contents * [Summary](#a-package-for-automatically-encrypting-and-decrypting-eloquent-attributes-in-laravel-55-based-on-configuration-settings) * [Requirements](#requirements) * [Schemas](#schemas) * [Installation](#installation) + [Step 1: Composer](#step-1-composer) + [Step 2: Enable the package (Optional)](#step-2-enable-the-package-optional) + [Step 3: Configure the package](#step-3-configure-the-package) * [Usage](#usage) * [Keys and IVs](#keys-and-ivs) * [Unit Tests](#unit-tests) * [Overrides](#overrides) * [FAQ](#faq) + [Can I manually encrypt or decrypt arbitrary data?](#can-i-manually-encrypt-or-decrypt-arbitrary-data) + [Can I search encrypted data?](#can-i-search-encrypted-data) + [Can I encrypt all my `User` model data?](#can-i-encrypt-all-my-user-model-data) * [Credits](#credits) * [Contributing](#contributing) * [License](#license) ## Requirements * Laravel 5.5+ * PHP >= 7.1.0 * PHP [OpenSSL extension]( ## Schemas Encrypted values are usually longer than plain text values, sometimes much longer. You may find that the column widths in your database tables need to be altered to store the encrypted values generated by this package. If you are encrypting long strings such as JSON blobs then the encrypted values may be longer than a `VARCHAR` field can support, and you will need to alter your column types to `TEXT` or `LONGTEXT`. ## Installation ### Step 1: Composer Via Composer command line: ```bash $ composer require austinheap/laravel-database-encryption ``` Or add the package to your `composer.json`: ```json { "require": { "austinheap/laravel-database-encryption": "0.1.0" } } ``` ### Step 2: Enable the package (Optional) This package implements Laravel 5.5's auto-discovery feature. After you install it the package provider and facade are added automatically. If you would like to declare the provider and/or alias explicitly, you may do so by first adding the service provider to your `config/app.php` file: ```php 'providers' => [ // AustinHeap\Database\Encryption\EncryptionServiceProvider::class, ]; ``` And then add the alias to your `config/app.php` file: ```php 'aliases' => [ // 'DatabaseEncryption' => AustinHeap\Database\EncryptionFacade::class, ]; ``` ### Step 3: Configure the package Publish the package config file: ```bash $ php artisan vendor:publish --provider="AustinHeap\Database\Encryption\EncryptionServiceProvider" ``` You may now enable automagic encryption and decryption of Eloquent models by editing the `config/database-encryption.php` file: ```php return [ 'enabled' => env('DATABASE_ENCRYPTION_ENABLED', true), ]; ``` Or simply setting the the `DATABASE_ENCRYPTION_ENABLED` environment variable to true, via the Laravel `.env` file or hosting environment. ```bash DATABASE_ENCRYPTION_ENABLED=true ``` ## Usage Use the `HasEncryptedAttributes` trait in any Eloquent model that you wish to apply encryption to and define a `protected $encrypted` array containing a list of the attributes to encrypt. For example: ```php use AustinHeap\Database\Encryption; class User extends Eloquent { use HasEncryptedAttributes; /** * The attributes that should be encrypted on save. * * @var array */ protected $encrypted = [ 'address_line_1', 'first_name', 'last_name', 'postcode' ]; } ``` You can combine `$casts` and `$encrypted` to store encrypted arrays. An array will first be converted to JSON and then encrypted. For example: ```php use AustinHeap\Database\Encryption; class User extends Eloquent { use HasEncryptedAttributes; protected $casts = ['extended_data' => 'array']; protected $encrypted = ['extended_data']; } ``` By including the `HasEncryptedAttributes` trait, the `setAttribute()` and `getAttributeFromArray()` methods provided by Eloquent are overridden to include an additional step. This additional step simply checks whether the attribute being accessed via setter/getter is included in the `$encrypted` array on the model, and then encrypts or decrypts it accordingly. ## Keys and IVs The key and encryption algorithm used is the default Laravel `Encrypter` service, and configured in your `config/app.php`: ```php 'key' => env('APP_KEY', 'SomeRandomString'), 'cipher' => 'AES-256-CBC', ``` If you're using `AES-256-CBC` as the cipher for encrypting data, use the built in command to generate your application key if you haven't already with `php artisan key:generate`. If you are encryp
