THEY LIVE

Steganographic Decryption, of sorts

A Chrome browser extension that decrypts images on a web page that are encrypted in a very particular (and trivial) way. All images are processed as if they are encrypted, except as restricted by the browser (see Known Issues).

This project is just-for-fun, mostly to look deeper into image manipulation using Javascript and the HTML5 canvas element.

Install

  • Download the extension ** Verify the current MD5 checksum: 071f9b5e5c17e5faf4220ecc19eedb1a
  • Open the Chrome extensions page: chrome://extensions/
  • Drag the extension file (theylive.crx) into the Chrome extensions page

(Chrome will warn you that the extension can "Read and change all your data on the websites you visit". That's true, and is understandably terrifying.)

Use

Once installed, click the "THEY LIVE" button in Chrome to decrypt images on the current tab (web page).

Known Issues

Due to browser security restrictions, this plugin will operate only on images loaded from the same site as the web page in which they are embedded.

Thanks

Thanks to Ben Mullins's "Burning Man Enhancer" Chrome extension for getting this started.
