Encryption DB Fields

This package allows two way encryption on all critical fields inside the database.

Allows search by encrypted field.

Installation

You can install the package via composer:

composer require oriamdev/encryption-db-fields

Setup Eloquent Model

1 - First, you need to add the trait EncryptAttributesTrait to the model when you want to encrypt fields.

    use EncryptAttributesTrait;

2 - Define the array with fields to be encrypted

    protected array $encrypts = ['name', 'email'];

3 - If you want to search by encrypted field you need to add the array $searchableEncrypts to the model.

    protected array $searchableEncrypts = ['name', 'email'];

Adapt DB Table structure

NOTES:

• The fields to be encrypted need to be text type.
• For each searchable field you need to add a string field to migration with name field_signature

Schema::create('users', function (Blueprint $table) {
    $table->id();
    $table->text('name'); 
    $table->text('email');
    $table->string('email_signature',10)->index();
    $table->string('name_signature', 10)->index();
    $table->timestamp('email_verified_at')->nullable();
    $table->string('password');
    $table->rememberToken();
    $table->timestamps();
});

Migrate database

php artisan migrate

CRUD Operations

The crud operations work the same way and the process to encrypt and decrypt fields are responsibility of the trait EncryptAttributesTrait

Validation Rules

The laravel validation rules unique and exists does not work but, not worry about it. The package has a Validation Rule Oriamdev\EncryptionUserDbAuth\Rules\Encrypted The construct need the fully qualified name of the model. User::class or Post::class

Check if field under validation is unique

After creating the new instance of Encrypted Rule you can pass the unique method

$request->validate([
     'email' => [(new Encrypted(User::class))->unique()],
]);

If the validation fails the rule return the default value of validation:unique

Check if field under validation exists

After creating the new instance of Encrypted Rule you can pass the exists method

$request->validate([
     'email' => [(new Encrypted(User::class))->unique()],
]);

If the validation fails the rule return the default value of validation:unique

$request->validate([
    'name' => [(new Encrypted(User::class))->exists()]
]);

Search by encrypted field

$user = User::findByEncrypt('email', 'mario@oriamdev.com');

The method findByEncrypt return an instance of model or null if not exists.
