This php script provides a unique random key with 32 characters and can be used to avoid the system to pass some primary keys across the url, by example.

function get_cripta()

{

        $year = date('Y');

        $month = date('m');

        $day = date('d');

        $hour = date('H');

        $min = date('i');

        $sec = date('s');

        $coef = rand(1,99999);

        $quo1 = ($year*$month*$day);

        $quo2 = ($hour+$min+$sec);

        $result = ($quo1*$quo2)*$coef;

        $final = md5($result);

        return $final;

}
