Crypto Challenge

Ok, I'll start off with an easy one. There is lots of ciphertext for whatever analysis you'd like to do. It's also not even a formal cipher, so you can still use punctuation and spacing to help. Reply with the solution, or partial solution if you're stuck.

If people are interested, but are having problems, I can start giving hints, but for now, here's the ciphertext.

Nice Crypto  (thumbsup) , Hooman. It took me like 1 and 1/2 hour to decipher it, but I'm too lazy  :yawn: and tired to write the whole text in one post  :lol:



one: conspiracy

Both wheels of the scooter left the ground as Axen sailed over the lip of the down ramp and into the tunnel that connected the hot lab with the rest of Eden colony. He touched down a third of the way along the ramp, the tires landing with a satisfying chirp that echoed off the metal-lied walls, motors whining in protest. He was breaking half a dozen safety regulation, driving like a teenager a third his biological age of forty-five.

He didn't care. First of all, he was mad, damn it it, and felt good to break a few regs(?), and second of all, nobody was around it to complain. The tunnels were almost deserted. Every adult who wasn't engaged in a service vital to the maintenance of the colony was in Nguyen's "town meeting," the meeting Axen Moon had walked out on.

... To be continued.
if anyone finds and communicate to us that which thus far has eluded our efforts, great will be our gratitude.

Yep. I took s_e01.rtf from Story.vol and encrypted it.

Care to give us any details about how you solved it? Any details you'd like to know about how it was encrypted? Or should I post another one, perhaps a little harder?

Btw, for the curious, the encryption/decryption key I used was "EDEN MISSION ONE". (Or at least the keyword used to generate the key).

Well, since you insist  :D . The first time I saw the crypto, it was really, really ,really daunting, but I gave it a shot. The trick is to look for the shortest words because they are the easier to decode; I saw words like "B", "N" ... standing alone. Those could only be "I" or "A" . You were kind enough not to alter the punctuation marks, so I looked for the apostrophes "'"; I saw stuff like "QUI'W" "QW'S" ... it looks like the letter that comes right after the "'" can only be "S" (like he's) or "T" (like can't) or "D" (it'd). It also helped to know that "'s" is most of the time preceded with pronouns or "isn" "aren"... Well, that's enough as of how I solved it. Once you get two or three letters decrypted, the other ones come by themselves.
I had a good time   ;)

I'm trying to write one, and I have to admit that it's really tedious. You have to make sure that you don't make any mistakes or don't skip any words, so I think you wrote a program that can do it for you, aren't I right? I was thinking about writing a program in C++ that could help me to do mine, but it's gonna take some time; untill I'm done, I think it would be really nice of you if you put another crypto challenge (harder).
Thx.  
if anyone finds and communicate to us that which thus far has eluded our efforts, great will be our gratitude.

Alright. I'll begin work on a harder challenge. This one I think will be a formal cipher. (All spaces and punctuation removed, and the text is broken into blocks of 5. If the text length isn't a multiple of 5, extra padding (random charaters) are added to the end to make it a multiple of 5).

And yes, I do have a program written to decipher these. Enciphering is similar, I just sorted and inverted my key by hand and used the deciphering algorithm on it. I shouldn't be so lazy and actually start writing a proper program. Maybe even release it for people attempting the challenge.

I'll be back shortly.

Oh, and btw, nice analysis. That wasn't quite what I was expecting but still very effective. And yes, there definately is a lot more info you can gain from the punctuation. That's partly why I didn't start off with a formal cipher. I figured an easier start would be more fun.

i tried to look for the most common letter (e) i knew that the letters with the highest count would be the vowels. but i gave u p in the end cos it was late

Hmm, now that sounds a little closer to the kind of thing I was expecting. (Hint, hint, nudge, nudge, for challenge #2).

Perhaps I should post some software to help out a bit? Or should I just leave people to their own devices?

just leave ppl 2 get on with it
for now

if you get no solutions then you start hinting. remeber some ppl visit the forum evry few days
and it may take time to work out
