自定义身份验证和密码加密laravel 5

目前，我正在一个laravel 5项目。我想用我的自定义加密密码，所以我做了一个功能，我尝试使用它。首先，我重写postLogin函数，并添加了新密码Encryption。自定义身份验证和密码加密laravel 5

public function postLogin(Request $request) 
{ 
    $email = $request->get('email'); 
    $password = $this->hashPassword($request->get('password')); 
    $this->validate($request, [ 
     $this->loginUsername() => 'required', 'password' => 'required', 
    ]); 

    // If the class is using the ThrottlesLogins trait, we can automatically throttle 
    // the login attempts for this application. We'll key this by the username and 
    // the IP address of the client making these requests into this application. 
    $throttles = $this->isUsingThrottlesLoginsTrait(); 

    if ($throttles && $this->hasTooManyLoginAttempts($request)) { 
     return $this->sendLockoutResponse($request); 
    } 

    $credentials = ['email' => $email, 'password' => $this->hashPassword($password)]; 

    if (Auth::attempt(['email' => $email, 'password' => $this->hashPassword($password)])) { 
     // Authentication passed... 
     return $this->handleUserWasAuthenticated($request, $throttles); 
    } 

    // If the login attempt was unsuccessful we will increment the number of attempts 
    // to login and redirect the user back to the login form. Of course, when this 
    // user surpasses their maximum number of attempts they will get locked out. 
    if ($throttles) { 
     $this->incrementLoginAttempts($request); 
    } 

    return redirect($this->loginPath()) 
     ->withInput($request->only($this->loginUsername(), 'remember')) 
     ->withErrors([ 
      $this->loginUsername() => $this->getFailedLoginMessage(), 
     ]); 
}

正如你可以在代码中看到，我调用的函数hashPassword，和这样的作品，但问题是，“验证::尝试”返回false往常一样，尽管我有我的数据库中的用户，用正确的数据。
任何解决方案，请？
非常感谢
亲切的问候
