Encryption

Introduction

Doppar's encryption services provide a simple, convenient interface for encrypting and decrypting text via PHP's OpenSSL using AES-256 and AES-128 encryption. All of Doppar's encrypted values are signed using a message authentication code (MAC) so that their underlying value cannot be modified or tampered with once encrypted.

Before using Doppar's encrypter, you must set the key configuration option in your config/app.php configuration file. This configuration value is driven by the APP_KEY environment variable. You should use the php pool key:generate command to generate this variable's value since the key:generate command will use PHP's secure random bytes generator to build a cryptographically secure key for your application. Typically, the value of the APP_KEY environment variable will be generated for you during Doppar's installation.

Encrypting a Value

To encrypt a value in Doppar, you can use the Crypt facade, which provides a simple and secure way to encrypt strings. Here's an example of how to encrypt a value in a controller:

You can use encrypt method to encrypt a string.

<?php

namespace App\Http\Controllers;

use Phaseolies\Http\Request;
use Phaseolies\Support\Facades\Crypt;

class UserController extends Controller
{
    public function store(Request $request)
    {
        $encrypted = Crypt::encrypt("Hello World");

        $encrypted // This is now encrypted
    }
}

Decrypting a Value

To decrypt a value in Doppar, you can use the Crypt facade, just like how you encrypt data. The decrypt() method provided by Phaseolies\Support\Facades\Crypt allows you to safely decrypt a previously encrypted string.

You can use decrypt method to decrypt a string.

<?php

namespace App\Http\Controllers;

use Phaseolies\Http\Request;
use Phaseolies\Support\Facades\Crypt;

class UserController extends Controller
{
    public function store(Request $request)
    {
        $decrypted = Crypt::decrypt($encrypted);

        $encrypted // This is now decrypted
    }
}
