Demystifying the Enigma Machine
Ever wondered how WWII’s notorious cipher device can be built with pure functions? This talk takes you on a journey from the Enigma’s rotors, reflector, and plugboard to an elegant F# pipeline using fold/reduce patterns. You’ll see how threading machine state through a series of functions not only models the device perfectly, but also makes the code super readable.
Along the way we’ll sprinkle in property-based tests to prove encryption/decryption symmetry, plus unit tests for each component. It’s a fun mix of historical cryptography lore and modern functional programming tricks that’ll leave you inspired to tackle complex systems in your own code.
