hi teknoid,
Thanks..I liked the idea of behavior..below is a attached behavior...
but still I need someone's help to complete the isHashed Method
<?php
App::import('Core', 'Security');
class CustomValidationBehavior extends ModelBehavior
{
function setup(&$model, $config = array())
{
}
/****
* Checks if a string is already hashed
* <b>Parameters</b>
* Model $model - reference to parent model
* Array $value - array
* Mixed $salt - either Salt String or boolean
* <b>Returns:</b>
* boolean - true if string is hashed
* - false if string is not hased
*/
function isHashed(&$model, $value = array(), $salt = false)
{
$string = array_shift($value);
//Check if salt value has to be used
if ($salt)
{
if (is_string($salt)) {
$string = $salt . $data[$this->name]['passwd'];
} else {
$string = Configure::read('Security.salt') . $string;
}
}
//Get Instance of Security
$security =& Security::getInstance();
//Check if string is md5 hashed
if($security->hashType == 'md5' && preg_match("/[A-Fa-f0-9]{32}/
i", $string)) return true;
//Check if String sha1 hashed
if($security->hashType == 'sha1' /* condition for sha1 */)
return false;
return false;
}
}
?>
