Question

I have an existing database I’m trying to put a cake app on top of. The old app used crypt() in Perl to hash the passwords. I need to do the same in the PHP app.

Where is the correct place to make that change in a standard cakephp app? And what would such a change look like?

I got it working…

here is my AppController:

class AppController extends Controller {     var $components = array('Auth');      function beforeFilter() {         // this is part of cake that serves up static pages, it should be authorized by default         $this->Auth->allow('display');         // tell cake to look on the user model itself for the password hashing function         $this->Auth->authenticate = ClassRegistry::init('User');         // tell cake where our credentials are on the User entity         $this->Auth->fields = array(            'username' => 'user',            'password' => 'pass',         );         // this is where we want to go after a login... we'll want to make this dynamic at some point         $this->Auth->loginRedirect = array('controller'=>'users', 'action'=>'index');     } } 

Then here is the user:

<?php class User extends AppModel {     var $name = 'User';      // this is used by the auth component to turn the password into its hash before comparing with the DB     function hashPasswords($data) {          $data['User']['pass'] = crypt($data['User']['pass'], substr($data['User']['user'], 0, 2));          return $data;     } } ?> 

Everything else is normal, i think.
