The Kryptos Sculpture
The Kryptos Sculpture is located in the center of the CIA Headquarters in Langley, VA. It was designed in 1990, and contains a four-part encrypted puzzle. The first three parts have been solved, but now we’ve learned that the second-part solution was wrong and here’s the corrected solution.
The fourth part remains unsolved. Wired wrote:
Sanborn has said that clues to the last section, which has only 97 letters, are contained in previously deciphered parts. Therefore getting those first three sections correct has been crucial.

Actually, many people have solved the last part. It uses the CIA’s best encryption method, and when you follow the instructions in the message to claim your prize, THEY KILL YOU! Problem solved! No need to find a better encryption method.
