The cryptex is fictional, but in the book The DaVinci Code, yes I believe that he was the one that supposedly created it.
Cryptex
Like, for example, "Slay It" by Cryptex. Something that really goes well with a fight or battle scene, like some kind of future space warrior.
In The Da Vinci Code, Robert Langdon realized the Fibonacci sequence was the key to solving the cryptex puzzle by recognizing the sequence in the numbers on the Vitruvian Man painting. He used the Fibonacci sequence to determine the correct order of the letters in the password.
