Information Hiding: Steganography done with JavaScript

This little demo here demonstrates the core functionality of my JavaScript library steganography.js. Basically it allows you to hide or read data in or from the alpha channel of any image.
Regarding the demo: first of all you may hide the text from the textarea inside any image - you have previously selected from your local filesystem - by using the "Hide"-button. After the new image with the text encoded inside is generated you may download it and distribute it with the secret message inside instead of the old boring messageless picture. As the second part it is possible to read a message encoded inside the selected image using the "Read"-button.
Note that there will be no message at all or some cryptic message if no alpha channel is set or the message is encoded with another algorithm, so I recommend you to use this demo to encode and decode the message.
