Usage

1. To embed the message hidden.txt into the monkey.jpg image:

   outguess -k "my secret pass phrase" -d hidden.txt monkey.jpg out.jpg

2. To extract hidden message from out.jpg

   outguess -k "my secret pass phrase" -r out.jpg message.txt

3. Embed a second message, use:

   outguess -k "secret1" -d hide1.txt -E -K "secret2" -D hide2.txt monkey.jpg out.jpg

4. Outguess will first embed hide1.txt and then hide2.txt on top of it, using error correcting codes.

5. The second message hide2.txt can be retrieved with

   outguess -k "secret2" -e -r out.jpg message.txt
