Updated to hopefully make it a bit clearer. Also there is an alternate challenge at izhack.com port 12346 but you can't read it in a browser. :)

- rachelbythebay 14y ago... just because you get a RSA thing (ahem) out of it doesn't mean it'll work with your "Step 2". Those things aren't armored, so it's possible to corrupt it and have no luck getting anywhere. Or did you intend for it to be straight-up frustrating?

- kator 14y agoNo it's designed as a challenge not designed to be frustrating. Think of reasons you think you see cipher text in it.. And there is nothing 'armored' about this thing, it's so plainly in your face I'm stunned nobody had figured it out yet.
- anonymous_ 14y agoKator, have you read Gödel, Escher, Bach: an Eternal Golden Braid?
- kator 14y agoIf you are trying to say I created a puzzle only I can solve you would be wrong. I have someone who solved it but they're into protocol analysis and crypto.
- anonymous_ 14y agoNo, I think it's solvable and even easy (depending on definition). Beforing you gave the tips I saw that "scrambled" trimmed the response always at the same byte length. Then I saw everytime it returned something different. Then, doing a "for i in $(seq 0 50); do curl izhack.com:12345 | head -7 | tail -1 | cut -c 1-250; done; I could see the pattern. Doing the same for the other lines, replacing head -7 with head -8, head -9, etc I grabbed the repetition columns for all 5 lines. Each line had different columns repeated. Creating a 5x300 grid and marking the cells where repetition occurs you see there's a symmetry. The repeats 5 times, where at column 58 every line repeats and it marks the repetition. This is where I left, I still don't know the meaning of the last line. When I first run, coincidentally the server returned "sAlt" :-) I was only asking if you knew the book because you seem to like puzzles and me too. As I liked the book I thought you might like and was trying to start a conversation. Sorry!
- anonymous_ 14y agoAh, you need a 300-column terminal to avoid line breaks :-)
- kator 14y agoI have a 254 column terminal :-) That said you will want to use code to analyze it.. You're very close..

- kator 14y agoOh you are soooo close.. And I'm not offended at all. I like puzzles but I like this have some sort of relationship to real life if possible.. :)
- rachelbythebay 14y agoLook, I got the thing extracted, or so I think. It's just not working. Go look at your syslogs and you should see the inbound failures.
- rachelbythebay 14y agoOkay, tell me this. Is this the right md5sum? 775361fdc57dca8689d99f2b390bf258 out That's including the full output from your not-really-HTTP server on 12345, specifically version "Jan 7 2013 16:37:48".
