Helps the user indicating, if he entered the correct password, by showing him a calculated image.
This script adds no functionality to the page. Its use case is to show the user, if he entered the correct password by showing him an image. This image is calculated by the entered password. If he mistypes a character, the image will be a different. So he instantly knows that it is wrong, before sending it to the server.
