Breaking Unbreakable Codes: The Evolution of Cryptography | Chaos Lever

 Welcome to another episode of Chaos Lever, where Ned and Chris explore the history, intrigue, and occasional absurdity of cryptography! 🤖🧠 This week, it’s Part Two of our deep dive into codes and ciphers, from ancient Rome’s Caesar cipher to Napoleon’s overly optimistic battlefield encryption. Discover how cryptography evolved to outwit spies, soldiers, and codebreakers, setting the stage for the digital cryptography we know today. Plus: existential robots, live skeeting, and crunchy peanut butter. 🥜 📚 

In This Episode: 
✨ Why polyalphabetic ciphers were unbreakable… until they weren’t. 
✨ How the Vigenère cipher held strong for 250 years. 
✨ The curious tale of Napoleon’s cracked code. 
✨ Charles Babbage: Mathematician, cryptographer, and all-around genius.
