如何替换cakephp密码哈希算法？

我有一个现有的数据库,我正试图把蛋糕应用程序放在上面.旧的应用程序在Perl中使用crypt()来散列密码.我需要在PHP应用程序中执行相同的操作.

在标准的cakephp应用程序中进行更改的正确位置在哪里？这样的改变会是什么样的？

我搞定了......

这是我的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');
    }
}

然后这是用户:

我认为其他一切都很正常.
