Laravel Database Encryption Package

Package for encrypting and decrypting model attributes for Laravel using openssl

Key Features

• Encrypt, Decrypt database fields easily
• Minimal configuration
• Include searching encrypted data using the following: whereEncrypted and orWhereEncrypted
• uses openssl for encrypting and decrypting fields

Requirements

• Laravel: >= 5
• PHP: >= 7.3

Schema Requirements

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.

We highly recommend to alter your column types to TEXT or LONGTEXT

Installation

Step 1: Composer

Via Composer command line:

composer require elgibor-solution/laravel-database-encryption

Step 2: Add ServiceProvider to your app/config.php file (Laravel 5.4 or below)

Add the service provider to the providers array in the config/app.php config file as follows:

'providers' => [
    ...
    \ESolution\DBEncryption\Providers\DBEncryptionServiceProvider::class,
],

Usage

Use the EncryptedAttribute 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:

class User extends Eloquent {
    use EncryptedAttribute;
        
    /**
    * The attributes that should be encrypted on save.
    *
    * @var array
    */
    protected $encryptable = [
        'first_name', 'last_name'
    ];
}

By including the EncryptedAttribute trait, the setAttribute(), getAttribute() and getAttributeFromArray() methods provided by Eloquent are overridden to include an additional step.

Searching Encrypted Fields Example:

Searching encrypted field can be done by calling the whereEncrypted and orWhereEncrypted functions similar to laravel eloquent where and orWhere.

namespace App\Http\Controllers;

use App\User;
class UsersController extends Controller {
    public function index(Request $request)
    {
        $user = User::whereEncrypted('first_name','john')
                    ->orWhereEncrypted('last_name','!=','Doe')
                    ->firstOrFail();
            
        return $user;
    }
}

Encrypt your current data

If you have current data in your database you can encrypt it with the: php artisan encryptable:encryptModel 'App\User' command.

Additionally you can decrypt it using the: php artisan encryptable:decryptModel 'App\User' command.

Note: You must implement first the Encryptable trait and set $encryptable attributes

Exists and Unique Validation Rules

If you are using exists and unique rules with encrypted values replace it with exists_encrypted and unique_encrypted

$validator = validator(['email'=>'[email protected]'], ['email'=>'exists_encrypted:users,email']);
$validator = validator(['email'=>'[email protected]'], ['email'=>'unique_encrypted:users,email']);

Frequently Asked Question

Can I search encrypted data?

YES! You will able to search on attributes which are encrypted by this package because. If you need to search on data then use the whereEncrypted and orWhereEncrypted function:

User::whereEncrypted('email','[email protected]')
	->orWhereEncrypted('email','[email protected]')
	->firstOrFail();

It will automatically added on the eloquent once the model uses EncryptedAttribute

Can I encrypt all my User model data?

Aside from IDs you can encrypt everything you wan't

For example: Logging-in on encrypted email

$user = User::whereEncrypted('email','[email protected]')
    ->filter(function ($item) use ($request) {
        return Hash::check($password, $item->password);
    }
)
->where('active',1)
->first();
