CIA's Kryptos -Does it Hold The Key to the Sequel to "The Da Vinci Code"?
Daily Galaxy: One of the few uncracked codes at the Central Intelligence Agency headquarters in Langley, Virginia is found in Kryptos, a wonder of technology, a sculpture sitting in a sunny corner of the headquarters courtyard.
"EMUFPHZLRFAXYUSDJKZLDKRNSHGNFIVJ" is the first line of the Kryptos sculpture, a 10-foot-tall, S-shaped copper scroll perforated with 3-inch-high letters spelling out words in code resembling a piece of paper emerging from a computer printer. Completed 15 years ago, Kryptos, which is Greek for "hidden," at first attracted interest from government code breakers who deciphered the easier parts without announcing their findings publicly.
The main sculpture is made of red granite, red and green slate, white quartz, petrified wood, lodestone and copper, and is located in the northwest corner of the headquarters courtyard. The characters consist of the 26 letters of the standard alphabet and question marks cut out of the copper. This "inscription" contains four separate enigmatic messages, each apparently encrypted with a different cipher.
Mystery lovers around the world have joined members of the national-security establishment in trying to crack the rest. So far, neither amateurs nor pros have been able to crack the code.
