如何替换cakephp密码哈希算法？

namespace App\Auth;

use Cake\Auth\AbstractPasswordHasher;

class CustomPasswordHasher extends AbstractPasswordHasher
{
    public function hash($password)
    {
        // 实现自定义哈希算法
    }

    public function check($password, $hashedPassword)
    {
        // 实现自定义哈希算法的密码检查
    }
}

use App\Auth\CustomPasswordHasher;
use Cake\Auth\Middleware\FormAuthMiddleware;

// ...

$authentication = new FormAuthMiddleware([
    'loginRedirect' => '/',
    'authError' => '您无权访问该页面',
    'authenticator' => [
        'className' => 'Cake\Auth\FormAuthenticator',
        'passwordHasher' => new CustomPasswordHasher(),
    ],
]);

$middlewareQueue->add($authentication);
