Yes. As I said, the first one was easy. The first message had a 512 byte
random payload straight out of /dev/random. The second message had a
single cr for payload (outguess won't let you add zero length files).
Next step would be to use same approach on pictures of different origins
and quality. Large pictures with low compression rate.
The step after that would be telling /dev/random from an encrypted
message. Still game?
