Breaking The Code To The Catcher In The Rye discussion

I was looking for something and came across this:

https://en.m.wikipedia.org/wiki/Kryptos
The name Kryptos comes from the Greek word for "hidden", and the theme of the sculpture is "intelligence gathering." The most prominent feature is a large vertical s-shaped copper screen resembling a scroll, or piece of paper emerging from a computer printer, half of which consists of encrypted text. The characters are all found within the 26 letters of the standard Latin alphabet, along with question marks, and are cut out of the copper. The main sculpture contains four separate enigmatic messages, three of which have been deciphered.[1]
