Class CreateEgg

java.lang.Object
  CreateEgg

public class CreateEgg
extends java.lang.Object

This program can be used to generate Easter eggs for inclusion in software that is based on HTML pages. It works by accepting the query string that is to be used to access the easter egg, generating an MD5 hash of the query string that should be used to determine when the user has entered that query string in the URL (so that the clear-text query string does not appear in the application source), and then reading a file with the data that should be displayed when this egg is invoked and re-writing it to a DES-encrypted file with a key of the clear-text query string.
