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 wrote the program myself. In this case, I used the Processing.org Java library.

Re: Cryptography Challenge #21!

| 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 |
