How to Encrypt and decrypt a string in laravel

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 the command php artisan key:generate. It will generate secure random bytes to build your code. If this value is 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 figure 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.
