Found them!!

Aha, I've successfully temporarily derailed this thead. 😉

These feed are kind of handy, but it would be much nicer if you could go down to the specific thread level and even be able to read comments and such (now I'm just wishful thinking).

Thanks for looking those up P.

Ok, Onion. Nice one.

I am not going to say the password, in case someone else wants to try to solve this.

If you want to see it, you can click the link below. However, if you want to solve it on your own, do NOT click the link, as it will reveal the hidden message and the "password."

Show me the solution!

Of course, here is how I decoded it:

Show me the source code!

Incidentally, I have an image with something hidden in it too. Unfortunately, you'll need IE to see it, but here it is:

Hidden Image

Careful... it's not what you think...

Heh. You're such a joker..

[BuzzLY]

Really? Then PM me with the answer... 😉

[drag0n]

So he didnt get the right answer?
If he did, how would you know which Steganography decoder to use?

[Mordecai]

Heh, what funky font is this? 🙂

[BuzzLY]

The term "steganography decoder" is a bit of a misnomer. There are many different methods of steganography -- some simple, some complex.

For instance, you could write a message on your shaved head, and let your hair grow back to cover it up. The "steganography decoder" would be a set of clippers, and wouldn't be to hard to figure out how to use.

Once I determined that he modified the LSB, I simply iterated through each bit, and found a pattern. There was no cryptography used -- I simply used a different color depending on whether I found a 1 or a 0 at that particular pixel.

Thats the code I wrote to create the challenge.

Since Buzzly put up a SIRDS image for his challenge, I'm going to (try to..) write a SIRDS/SIS generator. For a laugh..

[Weedpacket]

onion2k: check your PMs.

'course, I didn't use PHP. I felt obligated to write some scripts to mess around, but why spend hours coding to try out an idea that could be checked in a few minutes with the Gimp?

I, for one, am stumped. Seems less like a puzzle and more like a lesson in learning steganography methods.

Aye; for this to be a PHP programming challenge, it would have been more appropriate to ask people to write something to do the embedding.

[onion2k]

Well, WeedPacket and Buzzly solved the puzzle. Well done to them.

I'll think up another one some day.
