Kryptos is a sculpture made by the US artist Jim Sanborn. It is located next to the headquarters of the CIA in Langley, VA. An encrypted message was written on the sculpture. The message consists of four independent parts.

The first three parts have been solved, but the fourth one has so far withstood every attempt at decryption.
