Info to Decipher Secret Message in Kryptos Sculpture at CIA HQ Auctioned for Nearly $1M (apnews.com)

An anonymous reader shared [1]this report from the Associated Press :

> The information needed to decipher the last remaining unsolved secret message embedded within a sculpture at CIA headquarters in Virginia sold at auction for nearly $1 million, the auction house announced Friday. The winner will get a private meeting with the 80-year-old artist to go over the codes and charts in hopes of continuing what he's been doing for decades: interacting with would-be cryptanalyst sleuths.

> The archive [2]owned by the artist who created Kryptos, Jim Sanborn , was sold to an anonymous bidder for $963,000, according to RR Auction of Boston. The archive includes documents and coding charts for the sculpture, dedicated in 1990. Three of the messages on the 10-foot-tall (3-meter) sculpture — known as K1, K2 and K3 — have been solved, but a solution for the fourth, K-4, [3]has frustrated the experts and enthusiasts who have [4]tried to decipher the S-shaped copper screen... One side has a series of staggered alphabets that are key to decoding the four encrypted messages on the other side.

"The purchaser's 'long-term stewardship plan' is being developed, according to the auction house."

But by looking at the author's notes rather than figuring solving the encryption.
