Strange Loop

Famous Unsolved Codes: Kryptos

Kryptos is an encrypted sculpture in the middle of CIA Headquarters in Langley, Virginia. Comprised of large copper sheets engraved with thousands of characters, it carries a series of ciphers. Three of the four have been solved, but the fourth section, 97 characters at the very bottom, remains uncracked. It is one of the most famous unsolved codes in the world, even referred to in Dan Brown’s “Da Vinci Code”-sequel “The Lost Symbol”. St. Louis cryptographer Elonka Dunin (namesake for the "Nola Kaye" character in Brown’s novel), and one of the few people from outside the CIA to have seen the sculpture in person, will review the sculpture’s history, going over the parts that have been solved, and discussing efforts to crack the famous unsolved section, K4.
