Demystifying the Enigma Machine – a Functional Journey
Ever wondered how the WWII Enigma cipher box actually worked (and why it eventually got busted)? Isaac Abraham takes you on a time-traveling ride through its history and inner mechanics—rotors, reflector, plugboard and all—then shows how you can model that very same machinery in F# using slick pipelines of pure functions.
Along the way you’ll get a crash course in functional design patterns (fold/reduce, anyone?) and see how property-based testing and good old unit tests make sure your F# version locks and unlocks messages just like the real deal. It’s part crypto-mystery, part coding deep-dive, and 100% nerdy fun.
