I actually came across this topic earlier today and
tried my darndest to understand what OP is trying to convey. I couldn't, so I moved on and didn't respond. Archeological findings of
old cryptographic tools have already been discovered before, so he wouldn't be the first...I'm pretty sure it's a joke-type of post. However, now that you've asked the question of, "have cryptographic mathematics even existed centuries?", I couldn't resist responding here:
Yes, they most certainly have.The invention of the frequency analysis technique for breaking monoalphabetic substitution ciphers, by Al-Kindi, an Arab mathematician,[19][20] sometime around AD 800, proved to be the single most significant cryptanalytic advance until World War II.
