How to Encrypt and decrypt a string in laravel * DevRohit Think simplified

Hi guys,

In this tutorial, we’ll learn how to encrypt and decrypt a string in Laravel. AES-256 and AES-128 encryptions are provided by Laravel using the OpenSSL algorithm. To encrypt information, Laravel employs a message authentication code. After encrypted values not be modified.

Configuration:-

After running command php artisan key:generate. It will generate secure random bytes to build your code. If this value does not set accurately, all values encrypted by laravel will be insecure.

Using The Encrypter:-

You are encrypting a value using an encrypting method of Crypt Facade. They encrypt all encrypted values with OpenSSL and AES-256-CBC cipher.

<?php 
namespace App\Http\Controllers; 
use App\Http\Controllers\Controller; 
use App\User; 
use Illuminate\Http\Request; 
use Illuminate\Support\Facades\Crypt; 
class UserController extends Controller 
{ 
    /** 
     * Store secret message for the user. 
     * 
     * @param Request $request 
     * @param int $id 
     * @return Response 
    */ 
    public function storeSecret(Request $request, $id) 
    { 
        $user = User::findOrFail($id); 
        $user->fill([ 
           'secret' => Crypt::encryptString($request->secret), 
 ])->save(); 
    } 
}

DecryptString:

You can decrypt values using the decryptString method of Crypt Facade. If the value does not decrypt well, it will throw an exception of DecryptException.

use Illuminate\Contracts\Encryption\DecryptException; 
use Illuminate\Support\Facades\Crypt; 
try { 
      $decrypted = Crypt::decryptString($encryptedValue); 
 } catch (DecryptException $e) { // }

I hope that this post (How To Encrypt And Decrypt A String In Laravel) has helped you’ve figured out how to set up the encryption key. It can also encrypt and decode strings. I used this site to write this post. Please leave a remark if you have any queries, and I will answer as quickly as possible.
