What does Kryptos say?

Kryptos is a sculpture containing four encrypted messages. Only the first and part of the second message have been officially solved. Here's what we know:

* K1: This message has been solved and reads: "BETWEEN SUBTLE SHADING AND THE ABSENCE OF LIGHT LIES THE NUANCE OF IQLUSION" (Note the misspelling of "illusion" is part of the original ciphertext).

* K2: Parts of this message have been solved, with the help of hints from the sculptor, Jim Sanborn. The solved portions provide clues related to the historical context and use of specific cipher techniques. However, a significant portion remains unsolved.

* K3 & K4: These messages remain completely unsolved.

Therefore, a complete answer to "What does Kryptos say?" is not possible at this time. Only a fraction of the entire sculpture's text is publicly known.
