For 35 years, cryptographers have tried to crack the hidden code in the imposing copper sculpture in the courtyard of the CIA’s Virginia headquarters.
Kryptos, erected in 1990, features a wall of encrypted text hiding four messages, etched into what appears to be a piece of paper emerging from a printer.
