Hashing

Introduction

The Laravel Hash facade provides secure Bcrypt hashing for storing user passwords. If you are using the built-in LoginController and RegisterController classes that are included with your Laravel application, they will automatically use Bcrypt for registration and authentication.

Bcrypt is a great choice for hashing passwords because its "work factor" is adjustable, which means that the time it takes to generate a hash can be increased as hardware power increases.

Basic Usage

You may hash a password by calling the make method on the Hash facade:

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use App\Http\Controllers\Controller;
 
class UpdatePasswordController extends Controller
{
/**
* Update the password for the user.
*
* @param Request $request
* @return Response
*/
public function update(Request $request)
{
// Validate the new password length...
 
$request->user()->fill([
'password' => Hash::make($request->newPassword)
])->save();
}
}

The make method also allows you to manage the work factor of the bcrypt hashing algorithm using the rounds option; however, the default is acceptable for most applications:

$hashed = Hash::make('password', [
'rounds' => 12
]);

Verifying A Password Against A Hash

The check method allows you to verify that a given plain-text string corresponds to a given hash. However, if you are using the LoginController included with Laravel, you will probably not need to use this directly, as this controller automatically calls this method:

if (Hash::check('plain-text', $hashedPassword)) {
// The passwords match...
}

Checking If A Password Needs To Be Rehashed

The needsRehash function allows you to determine if the work factor used by the hasher has changed since the password was hashed:

if (Hash::needsRehash($hashed)) {
$hashed = Hash::make('plain-text');
}
