Enigma, an interactive web-based walkthrough.
Raw Developer Origin & Technical Request
Hacker News
May 27, 2026
I recently went on a long walk (to get newborn twins to nap) and ended up having a long discussion with ChatGPT in voice mode; asking it to explain how the Enigma machine worked and clarifying all the errors in my current understanding.I ended up going right back to basics and then subsequently spent ages failing to understand how it was cracked.
Anyway, I built this in an attempt to recreate that arc for people (like me) who find Enigma intimidating: 13 stages, ~15 minutes, ending in a sandbox machine and the "no letter encrypts to itself" flaw that doomed it.Built with React + SVG + GSAP. Rotor wirings and stepping are historically accurate; an Advanced toggle exposes Ringstellung and M4. Feedback very welcome, especially on stages that drag or lose you.
