Kryptosis an code sculpture installed atCIAheadquarters in Langley , Virginia . It ’s a set of huge copper plates with enciphered textual matter chip at into them — for example , one segment readsTWTQSJQSSEKZZWATJKLUDIAWINFBNYP(though it looks a deal decent in context ) .

Although the carving was set up in 1990 , it took until 1999 for someone to actually decrypt part of the message : of the four segment of text , three were decrypted ( complete with intentional spelling error introduce by the sculptor , Jim Sanborn ) . The quaternary segment remains encrypted , though there is animpressive online effortto decrypt it . Sanborn isreportedly so frustratedthat the stay bit has not been break-dance that he start giving out hints in 2010 — still no discovery . He has also confirmed that in the event that he break down before the decryption take place , the solution can still be confirmed . Jeepers .

The sculpture is vex for many reasons . First , you have the fact that encrypt text is sit in a CIA courtyard , and part of that schoolbook is unknown — despite being surrounded by some of the world ’s bestcodebreakers . secondly , the school text thathasbeen decipher is totally bonkers , and seems to sharpen to other puzzle and even an ancient crypt . Here are the segments that have been decrypted ( take note that misspellings and rum punctuation mark are designed ):

That last bit is a reference to Howard Carter ’s opening of thetomb of King Tut , so it ’s notentirelythe ravings of a delirious artist .

Kryptosshows up occasionally in pop music civilisation — including on an episode of the Showtime seriesHomeland . It has also appeared onAliasand in Dan Brown ’s novels . Game developer Elonka Dunin is deliberate the go expert on the sculpture , and Dan Brown apparently named a character after her ( though he anagrammed and abbreviate the name to " Nola Kaye " ) .

So , the unresolved school text isstill out there . Are you good at puzzler ?
