NSA cracked CIA "Kryptos" sculpture before CIA

Kim Zetter: "It took more than eight years for a CIA analyst and a California computer scientist to crack three of the four coded messages on the CIA's famed Kryptos sculpture in the late '90s. Little did either of them know that a small group of cryptanalysts inside the NSA had beat them to it, and deciphered the same three sections of Kryptos years earlier — and they did it in less than a month, according to new documents obtained from the NSA."
