Kryptos is one of the biggest, most enticing unsolved mysteries around, so it’s tempting to think that there’s some sort of greater X-Files conspiracy behind the release of the third clue. However, according to the New York Times, the answer is likely much simpler. Sculptor Jim Sanborn is 74 years old, and he’s been fielding constant questions about the cyphered messages for no less than three decades. He says he didn’t believe the mystery would take this long to solve, and it’s probably safe to say he certainly didn’t expect cryptography enthusiasts to actually turn up at his door to discuss the possible solution. As Sanborn is fairly old and starting to find the whole Kryptos mess “exhausting,” he has started to look into ways to pass on his arcane knowledge (of the solution of the fourth text, that is). He says he has actually decided to auction off the secret, complete with his patented online solution verification process that costs $50 per attempt. 

The New York Times article insinuates pretty heavily that the release of the third clue may simply be an attempt to have someone finally solve the mystery, so Sanborn doesn’t have to bother with anything Kryptos-related ever again. Still, even if the secret eventually goes to auction and will be bought by the cryptography community’s equivalent to Martin Shkreli, at least Sanborn has made sure that the profits will be directed to funding climate research. So, you know, silver linings.
