Breaking Enigma with the Power of Modern C++
summary
Claims a modern desktop can break Enigma using optimized C++: a C++20 implementation with C++20 parallel algorithms, compile‑time rotor wiring, spans/string_view and simple microbenching. On a 16‑core CPU the search drops from an estimated 10^26 to practical billions; naive run is ~52 hours, threaded ~3–4 hours, further pruning and crib strategies push it to minutes. It tests against a real dataset—the 370‑char U-534 message (p1030681)—and finds the daily key, so the prototype reduces search to ~8 billion and succeeds.
