Hello Readers ,

Their are many methods to hash password in cakephp like cakephp alias , md5 etc blowfish is also one of them . One thing we have to note down that we can’t use Blowfish if we already have a database filled with passwords hashed using another method.

In the AppController write this code .

<?php
class AppController {

    public $components = array(
        'Auth' => array(
            'authenticate' => array(
                'Form' => array(
                    'passwordHasher' => 'Blowfish'
                )
            )
        )
    );
}

Use before save method to hash the password . In the User Model.

<?php
App::uses('BlowfishPasswordHasher', 'Controller/Component/Auth');

class User extends AppModel {

    public function beforeSave($options = array()) {
        // if ID is not set, we're inserting a new user as opposed to updating
        if (!$this->id) {
            $passwordHasher = new BlowfishPasswordHasher();
            $this->data[$this->alias]['password'] = $passwordHasher->hash($this->data[$this->alias]['password']);
        }
        return true;
    }
}

In the User Controller .

<?php
class UsersController extends AppController {

    public function login() {
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                return $this->redirect($this->Auth->redirectUrl());
            } else {
                $this->Session->setFlash( __('Username or password incorrect'));
            }
        }
    }
}

And that’s all there is to it.
