If I solved it (and I think I did) then I must kill myself for not solving it earlier... I just hadn't enough time back when it was recently posted.

And indeed... one needs the right tools, I agree with Ippiki-san there, I couldn't solve it at Uni's pc since there I didn't have the "right" tools... XDD just the default one, you know what I mean XDD.

BTW, if you're wrong, do you get the chance to try again?... and do I get a PM back saying "you failed, try again?".

Just wondering, thanks!

For this one, you could try Photoshop.

Should we analyze the images individually or together?
Are we looking at the binary because the images are black/white?

The message is stored visually, but can only be retrieved when you examine both images together.

I'm not quite familiar with photoshop but at least I managed to finish it with MSpaint with some luck :P

May I ask..what kind of program did you use to encode the message like this?

Re: Cryptography Challenge #21!
Link | by gendou on 2011-06-18 12:50:40
I wrote the program myself.
In this case, I used the Processing.org Java library.

Also managed to finish with paint. Lovely and interesting, Using a program such as paint or photoshop should be used as a hint, or considered a spoiler :d
