 		Maybe taking the numbers as 1337 letters and then ROTing everything...

 		Hmmm.
Has anyone tried a ROT-pi? The first letter or word ROT-3, then ROT-1, then ROT-4...

I'm trying it by hand, but it's not seeming to accomplish anything useful. Still, not being sure if it's 0-9 or 1-0, or perhaps if there's not a 0 at all... (if you put the zero at the tail after 9, it ALMOST looks like real words for a minute.)

 		Dude, I didn't know you could ROT-pi.

Sure, we just had to throw out a bit of leftover pumpkin pie from Thanksgiving that had become moldy...

 		If JohnEvans had a sibling that could post a related pun, that would be great.

Then we would really have pun-kin pie.

 		Stop! I can't take this kind of pun-ishment!

Anywho, I got the steg password! Even though I can't post the actual stegged picture, I'll spoiler the answer anyway.

Spoiler (Rollover to View):
References to Hitchhiker's Guide and having answers which aren't helpful lead to the key phrase "What's the question?" Originally I tried using jsut "question", but the nefarious Alexander elected to use the whole phrase as a password. In any case, the destegged text reads:

"?tuo ti derugiF"

Which is, of course, "Figured it out?" bacwards. That hardly seems worth the effort to steg, but hey: it's a clue.


So there we have it. Now what?

 		Got it!

Spoiler (Rollover to View):
The rotating key is "123456789A-Z" and the keystream is pi -backwards-. (got that from ?tuo ti derugiF)

ie. for the last word: mzyx with keystream 1413.

Anywho, rotting through the message does indeed get an irritating leetspeek message, which I have translated for easy reading:

"omg wtf: doo, yor workin for da black hats. Phear da technocrats, dey Nazi."

This also explains why I got this email. It's from a character in a roleplaying game I am in.


Well, that settles that. Unless I get more email from this guy, adieu. Thanks for the help!

 		As someone who is trying to become better at cryptography, I would appreciate it if you could explain what you mean by rotating key and key-stream, and how they are used to decode this message?

 		Allright, just for you Baelfael. Cause I like your style, kid. You've got chutzpah. Vim. Balls. Pith. That little something.

What was I talking about again?

Oh, right.

Spoiler (Rollover to View):
Allrighty.

We have our ciphertext:

"9099, ... btt mzyx."

We have our rotating key, which I guessed was "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ" because the ciphertext incorporated both letters and digits. It's a rotating key because the cipher works like this: you take a letter. you take a number. you move the letter forward in your key that number of spaces; ie. rotate it. W ROT-7 becomes 4.

Now what we need is a keystream, which is a series of numbers to use for rotating the letters in the text we want to encode. In this case, it's pi backwards. Because pi (as far as we know) is infinite, you can't just start with the end. So, I put the first number at the end of the message.

I suppose that's a tad confusing, so here's the practical application:

btt mzyx <-- ciphertext
295 1413 <-- keystream
D3Y N4Z1 <-- end result after rotating letters through key
dey Nazi <-- translation of stupid leetspeek


Any questions?

Yes, I'm sure we have questions, but the answer is, and will always be (of course)...42.
