    It could be, but you could produce a key to have the first 18 characters be anything. So all that was done there was pick a message then generate a key. Since the key is gibberish then I doubt it is the correct message.

    As has been pointed out, you can make the text say anything by coming up with a nonsense key. I think this is a false direction.

    I just moved all the Message X-1 stuff to this thread from "Top Menu".

    Similar to Kryptos K1 puzzle?

    While researching the autokey cipher, I came across a number of references to the Kryptos puzzle at the CIA (I think someone else mentioned Kryptos as well). There are some similarities to Kryptos. The Kryptos puzzles were named K1, K2, K3, and K4 (we have X-1). The cipher text in the Kryptos puzzles was arranged as a square, same as our puzzle. The first two Kryptos puzzles were based on autokey ciphers. We have been given a hint that our puzzle uses an autokey cipher.

    So if X-1 is inspired by Kryptos, then we may actually need to find *two* keys. The solution to Kryptos used a non-standard Alphabet key of "KRYPTOS" for the encoding table. So instead of using ABC....XYZ as the first line, it used KRYPTOSABCDEFGHIJLMNQUVWXZ (see http://www.thekryptosproject.com/kry...1_solution.php), and a key of "PALIMPSEST".

    I found an online decrypt tool online that allows you to enter both an alphabet key and and a passphrase, so you can experiment:

    I think we may need another hint.

    Yeah, I had initially been using that tool with the old "TESLAbcdfghijkmnopqruvwxyz" alphabet from a previous encrypted clue.
    But came to the (possibly mistaken) conclusion that we wouldn't have to guess an alphabet and a key at the same time!
    Oh well, time to try plan B.

    Hmmm... x-1 could be like alphabet "xywvutsrqponmlkjihgfedcbaz"...

    I fiddled with it quite a bit last night and came to the conclusion that we're missing an additional piece of information and/or set of assumptions.

    I'm not saying we haven't been given that information (or couldn't intuit the assumptions), but I don't thing we've identified them yet.

    I agree. I have been messing around with that site for an hour. Doing some tactics "TESLATESLATESLATESLA..." as the key to see if 5 letters in a row show up correctly (I shifted every thing 0-[wordlength] also. I tried a number of repeated words and wasn't getting anything promising at first glance. This leads me to believe we need to come up with the correct 'alphabet key' or 'tabula recta' in addition to the actual key.

    maybe x-1 is "abcdefghijklmnopqrstuvwyxz" 'x' shifted one to the right?

    Either way we need 2 keys to solve this cipher. A full alphabet, and then a key to start off the decoding.

    It's so amusing that even the section moderator has no clue what is going on.

    I know. I felt obligated to put in some time today. Plus I am fiercely interested again.

    And that 'alphabet key' set is going to be WAY too big to brute force. We must have some clues somewhere.

    The tool we are using fills out the alphabet for us, throwing out duplicate letters.
    So, for instance if you put in alphabet-key MODELS, you will see it shows "Alphabet Used: MODELSABCFGHIJKNPQRTUVWXYZ"
    So, I think we are just looking for two passwords (Alphabet Key + Passphrase). I already tried a bunch of combos like "ROADSTER" + "MODELS"
    "TESLA" + "MOTORS", etc.
    Also, I think we need to make sure to select the "Decrypt" option from the pulldown on the site...

    Once we find the correct two words/phrases then the text in the bottom box should show a readable message.
    At least, I think this is what we need to do.
