History of Math Project - The History of Cryptography!

Hello everyone! I just wanted to show you all a little bit of what I have been doing in my math history class: a journal article review! This is something a little different from what I usually do, but I thought: Hey! It might be a nice little addition to my YouTube Channel. Links are below: The article for the paper (Paywall, unfortunately): Charles F. Rocca Jr. (2014) Mathematics in the History of Cryptography, Cryptologia, 38:3, 232-243, DOI: 10.1080/016111942014315254 https://doi.org/10.1080/016111942014915254 The Greek Scytale: https://www.britannica.com/technology/scytale Thomas Jefferson's Wheel Cipher: https://www.monticello.org/site/research-and-collections/wheel-cipher President Garfield's Proof: https://www.maa.org/press/periodicals/convergence/mathematical-treasure-james-a-garfields-proof-of-the-pythagorean-theorem Monoalphabetical Ciphers: https://www.dcode.fr/monoalphabetic-substitution Enciphering/Deciphering/Attacking Hill Ciphers: https://www.nku.edu/~christensen/Section%209%20Hill%20cipher%20cryptanalysis%20new%20examples.pdf Thank you so much for watching!
