Good evening. Listen up, cryptographers and anyone who likes playing the game Clue: The CIA’s most-famous unsolved puzzle is going up for auction.

Quick background: Kryptos, a world-famous cryptography sculpture at the CIA’s headquarters in Langley, Virginia, was installed in 1990 by artist Jim Sanborn with guidance from retired CIA cryptographer Ed Scheidt. It contains four coded passages.

  • Three have been deciphered, yielding a fragment of poetry, a deliberate misspelling of “illusion,” and an account of Howard Carter peering into Tutankhamun’s tomb.
  • The final section—a 97-character passage known as K4—remains one of the world’s most famous unsolved ciphers.

Many have tried to figure it out. Sanborn told the New York Times that he’s received tens of thousands of emails over the decades from people guessing that they’ve cracked the code (they didn’t). At one point, he began charging $50 per emailed guess simply to manage the deluge of amateur solutions, and is now ready to pass the responsibility of sifting through them to someone else.

The money code: On his 80th birthday this November, Sanborn will auction off the full solution to K4, along with his original notes and prototypes, for an expected price of $300,000-$500,000.
