2007-02-26	0.3	hofsve	fixed: NOW you can move the output in a userdefined folder, because the created labyrinthfiles are reading out there own installationpath to correct the "installationpath" in the src-attribute of every generated <script src="..." ..></script>

Description

This userscript creates an encrypted version of your file and generates a little labyrinth of encrypted js-files (with a radomized number in the filename) around it. EnryptJS won't touch your original script-file.

It will be hard to find your enrypted script on the webserver, if now directory-listing is available.

The structure of attached example is:

• EncryptJS.html calls example_encrypted.js
  • example_encrypted.js calls example_01655034085806249.js
    • example_01655034085806249.js calls example_040666609552426813.js
      • example_040666609552426813.js calls example_07906913613952911.js
        • example_07906913613952911.js calls example_0734651380546169.js
          • example_0734651380546169.js calls example_022776101722639075.js
            

Additional information:

1. The script will prompt for then number of js-files in the labyrinth. The deault-value is 5, but you can change the number, if you think, that you need more or less files for your labyrinth.
2. Every encrypted javascript-file get it's own labyrinth!
3. All generated files will saved automaticly in the same folder as your original file.

      Include following line into your HTML-page and replace <path> by the real relative or absolute path of the JavaScript on your server.
        <script type="text/javascript" src="<path>/example_encrypted.js"></script>
      
      IMPORTANT: Make sure that all generated files are placed in the same folder.
    

Now this html-page will present, that the labyrinth works. The document contains only following "inlude":

    <script type="text/javascript" src="<path>/example_encrypted.js"></script>
    

The original file contains following line (see example.js in the example-folder):

      alert( 'Hello!\nI\'m the last script in the labyrinth!' );
    

It's encoded source was saved in file #5 ('example_022776101722639075.js').
