Does "WW", in K3, refering to William Webster?
There was a lot of speculation on this for a long time, but Sanborn finally confirmed the answer in January 2005: WW stands for William Webster, who was the Director of the CIA at the time that Kryptos was installed, and according to Sanborn was one of the driving forces in getting more art for the Agency. When Kryptos was dedicated in 1990, Sanborn gave an envelope to Webster which allegedly contained the answers (however, Sanborn has since said that the envelope did not contain the full story).
