Decrypting Kryptos

angkor writes "Kryptos is a sculpture located on the grounds of CIA headquarters in Langley, Virginia. Installed in 1990, its thousands of characters contain encrypted messages, of which three have been solved (so far). There is still a fourth section at the bottom consisting of 97 or 98 characters which remains uncracked."

Is there a solution?

[mistersooreams]

Forgive me for being cynical, but how can we be sure that this final piece is actually crackable? I mean, it would be a cruel joke by Jim Sanborn (the structure's creator) to just include a load of junk, but who's to say he didn't? The fact that the other parts have been deciphered suggests that this last part will give way eventually, but maybe that's just to make the final joke even crueler?

I hope I'm wrong because that would make this story a lot less interesting, but I just thought it should be mentioned.

It's certainly possible that the area people call "part 4" is actually random junk stuck in to fill up that section of the sculpture (the width of that portion is determined by the first two parts, and the height by the table on the right), and that the final solution to the sculpture uses entirely different elements.

If the end of the text is part 4, there's probably at least a part 5, because there's a bunch of other stuff in the installation not yet used in any solutions (including, for example, a compass that points the wrong way).

I wouldn't be surprised, from the known decryptions, if you had to stand with a candle at a certain point and notices the letters cut in the shadow cast by the sculpture at particular points. It seems to me like the bottom rows would be most likely as the letters for this, so it may be that some of the letters are important, but that there's no way to solve it by just looking at a transcript.

As a wonderful sci-fi connection, I suggest reading Cryptonomicron, by Neal Stephenson. Besides providing an excellent story (like all his books), it provides an extensive discussion of how code-breaking works, and how historically it evolved.

metaphorically solved section 4

Weird. This guy apparently metaphorically solved section 4. But he got an email from Jim saying "Dear John, this is not the way" Did he cheat? :)

My girlfriend took one look at it and saw an image embedded in the way the characters are laid out. She figures that a real message would be too obvious and since its art, the real purpose could simply be to see what is not plainly there.

Maybe the boys at Langley are being too literal at trying to solve it.
