How can i encrypt the password file and also how can use the Model

Answer 1

As you are using CakePhp go with framework's best practices.
When creating new user records you can hash a password in the
beforeSave callback of your model using appropriate password hasher
class:
App::uses('SimplePasswordHasher', 'Controller/Component/Auth');
class User extends AppModel {
public function beforeSave($options = array()) {
if (!empty($this->data[$this->alias]['password'])) {
$passwordHasher = new SimplePasswordHasher(array('hashType' => 'sha256'));
$this->data[$this->alias]['password'] = $passwordHasher->hash(
$this->data[$this->alias]['password']
);
}
return true;
}
}
You don’t need to hash passwords before calling $this->Auth->login(). The various authentication objects will hash passwords individually.
If you are using different model than User for authentication you need to define that in AppController. In your Case you need to do something like this in AppController:
$this->Auth->authenticate = array(
'Form' => array('userModel' => 'Login')
);
If you wish to hash your password, try this:
$hashedPassword = AuthComponent::password('original_password');
