1. Add component file to your app

Create this file app/controllers/components/password.php

Component Class:

<?php 
class PasswordComponent extends Object {
 
/**
 * Password generator function
 *
 */
    function generatePassword ($length = 8){
        // inicializa variables
        $password = "";
        $i = 0;
        $possible = "0123456789bcdfghjkmnpqrstvwxyz"; 
        
        // agrega random
        while ($i < $length){
            $char = substr($possible, mt_rand(0, strlen($possible)-1), 1);
            
            if (!strstr($password, $char)) { 
                $password .= $char;
                $i++;
            }
        }
        return $password;
    }
}
?> or download the file password.php (
http://deldan.com/downloads/password_component.zip).

2. Reference it on your controller

Refer the components on the controller together with the other components you may be using.

Component Class:

<?php 
var $components = array('Password', 'RequestHandler', 'Email');
?>

3. Use it in your controller

To use the component password , this is a simple example:

Controller Class:

<?php 
$newpass = $this->Password->generatePassword();
?>
