Ændre script - md5

Heey drenge...

Hvordan laver man dette script om så den gemmer som kryptet pass? (altså det der md5)

<?php
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;   
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "oprettelse")) {
  $insertSQL = sprintf("INSERT INTO oprettelse (Navn, `By`, Email, IP, KFROM, username, password, account) VALUES (%s, %s, %s, %s, %s, %s, %s, %s)",
                      GetSQLValueString($_POST['navn'], "text"),
                      GetSQLValueString($_POST['by'], "text"),
                      GetSQLValueString($_POST['email'], "text"),
                      GetSQLValueString($_POST['ip'], "text"),
                      GetSQLValueString($_POST['kfrom'], "text"),
                      GetSQLValueString($_POST['wishuser'], "text"),
                      GetSQLValueString($_POST['wishpass'], "text"),
                      GetSQLValueString($_POST['account'], "text"));
