The Laravel Hash facade provides secure Bcrypt hashing for storing user passwords. If you are using the AuthController controller that is included with your Laravel application, it 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:


namespace App\Http\Controllers;

use Hash;
use App\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class UserController extends Controller
     * Update the password for the user.
     * @param  Request  $request
     * @param  int  $id
     * @return Response
    public function updatePassword(Request $request, $id)
        $user = User::findOrFail($id);

        // Validate the new password length...

            'password' => Hash::make($request->newPassword)

Alternatively, you may also use the global bcrypt helper function:


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 AuthController included with Laravel, you will probably not need to use this directly, as the included authentication 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');
