Hi bakers,
I am trying to write a custom validation function that checks if a
string is already hashed or not. I want to make sure that password
filed are hashed and if not then hash them. Further, I can see it
being useful in many other cases. Pertaining to custom validation, I
have two questions
1. Where should I put validation function that are generic and not
particular to any model. Is app_model is the right place ? I just
don't want to put too many things in app_model and was thinking making
another file that holds custom validation functions.
2. Can someone help me completing this function. I got the start but
not being able to complete it
/****
* Checks if a string is already hashed
* <b>Parameters</b>
* String $string - input String
* mixed $salt - either string or boolean
* <b>Returns:</b>
* boolean - true if string is hashed
* - false if string is not hased
*/
function isHashed($string, $salt = false)
{
//Check if salt value has to be used - copied from Security.php
if ($salt)
{
if (is_string($salt)) {
$string = $salt . $string;
} else {
$string = Configure::read('Security.salt') . $string;
}
}
//Check if string is already hashed
$security =& Security::getInstance();
if($secuirty->hashType == 'md5')
if(preg_match("/[A-Fa-f0-9]{32}/i", $string)) return true;
return false;
}
