TIL of Kryptos, a sculpture outside of the CIA headquarters with four cryptographic puzzles on it - only three of which have been solved in almost thirty years.

The secret to a good crypto-puzzle-pack is to make one of those puzzles unsolvable

I always think I could probably solve this but then remember I’m a fucking idiot whose functionally illiterate.

whose functionally illiterate

Can confirm.

You know, if I were to make such a statue, I would intentionally include one unsolvable puzzle. Kind of extends the "shelf life" of the monument

No, he could just use a one time pad and the ciphered text is unbreakable. If you could determine from the output if the input was 'gibberish' or not it wouldn't be a very good cipher.

Come on, Reddit! Send me to Berlin. I will look at all the clocks.

The fourth unsolved hint mentions a clock, possibly "Berlin clock."

Downvoting person for making a reference to a detail in the article is quite rude.

Come on, Reddit! You can do this!

Right!? I just feel like with the advent of crowd sourcing, the hints the creator has already given, and the HUGE interest in cryptography thanks to cryptocurrencies, not to mention advancements in computing power, distributed networking and cloud computing... it just... SHOULD BE PUBLIC BY NOW!

I like to assume a few tiny handfuls of people have figured it out and now have great careers, but I'd like to know that it's been solved before the creator passes away.

That's actually a legitimate technique. The pioneers of cryptology waaaaaay back in the day (like centuries) would often include unsolvable Cyphers in their messages to throw off anyone who might want to steal it.

I feel like the creator might be more proud if it isn’t solved in his lifetime
