RubyConf 2024 Workshop: Building the Unbreakable Code Whose Breaking Won WWII by Aji Slater

After the last carrier pigeon but before digital encryption algorithms, there was the Enigma machine. An ingenious piece of pre-atomic age technology encoded German military secrets during World War II, baffling code-breakers with mere physical rotors, and switches, without elliptic curves or private keys. Delve into object-oriented programming and bring the Enigma machine back to life with an emulator built in Ruby. Use Test Driven Development to unravel the secrets of this nigh-unbreakable cipher device, witness OO principles unlock its mysteries, discover the power and versatility of the patterns we use as developers and how they mirror the Enigma's inner workings.
