cia kryptos sculpture code auction 2677451

An anonymous bidder has won the solution to the final unsolved puzzle of Kryptos, a famous encrypted sculpture at CIA headquarters in Virginia, for $962,500 in an online auction by R.R. Auction. The artist, Jim Sanborn, offered the handwritten code for the fourth message (K4) along with other unpublished items and a prototype, far exceeding the presale estimate of $300,000–$500,000. The sale came after the solution was accidentally leaked to journalists Jarett Kobek and Richard Byrne, who discovered the plaintext in Sanborn's papers at the Smithsonian's Archives of American Art, though they have agreed not to release it.

kryptos sculpture code cia 1234762958

An anonymous buyer paid $962,500 at an RR Auction sale for the code to the final unsolved passage of Jim Sanborn's sculpture "Kryptos," located at the CIA headquarters in Langley, Virginia. The sculpture, dedicated in 1990, contains four encrypted passages; three have been cracked by cryptologists, but the 97-character fourth passage (K4) has remained unsolved for decades. Sanborn, now 80, decided to sell the solution after growing tired of fielding inquiries from enthusiasts, despite a recent discovery of the solution in the Smithsonian's Archives of American Art that raised questions about the auction.
