Basic Usage

Encrypting A Value

You may encrypt a value using the Crypt facade. All encrypted values are signed with a MAC to detect any modifications to the encrypted string.

<?php namespace App\Http\Controllers;

use Crypt;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class UserController extends Controller
{
	/**
	 * Store a secret message for the user.
	 *
	 * @param  Request  $request
	 * @param  int  $id
	 * @return Response
	 */
	public function storeSecret(Request $request, $id)
	{
		$user = User::findOrFail($id);

		$user->fill([
			'secret' => Crypt::encrypt($request->secret)
		])->save();
	}
}

Note: Be sure to set a 32 character random string in the key option of the config/app.php file. Otherwise, encrypted values will not be secure.

Decrypting A Value

Of course, you may decrypt values using the decrypt method on the Crypt facade:

$decrypted = Crypt::decrypt($encryptedValue);
