With trembling hands, I made a tiny breach in the upper left hand corner… widening the hole a little, I inserted the candle and peered in… at first I could see nothing, the hot air escaping from the chamber causing the candle to flicker. Presently, details of the room emerged slowly from the mist, strange animals, statues and gold – everywhere the glint of gold. For the moment – an eternity it must have seemed to the others standing by – I was struck dumb with amazement, and when Lord Carnarvon, unable to stand in suspense any longer, inquired anxiously “Can you see anything?”, it was all I could do to get out the words “Yes, wonderful things”.

Kryptos at CIA headquarters in Langley, Virginia
KRYPTOS is a sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the four encrypted messages it bears. Of the four messages, the first three have been solved, while the fourth message remains as one of the most famous unsolved codes in the world. The sculpture continues to be of interest to cryptanalysts, both amateur and professional, who are attempting to decipher the fourth passage. The artist has so far given two clues to this passage.
In this post, I present the solution to Section III of the cypher as explained by the NSA. As I explained before, I do not like this method/explanation for several reasons. I do not think that this technique would appeal to an artist such Sanborn. Moreover, the way the question mark is handled is highly dubious. And finally, there is no explanation for the mysterious “Q” at the end of the message. Follow us on Twitter: @INTEL_TODAY Continue reading →
