I made a binary enigma machine for manual encryption
Introducing the 3D Printed Binary Enigma (10 Enigma) – the ultimate encryption and decryption device, no batteries required! Inspired by the iconic Enigma machines of WWII, this sleek and intuitive device lets you encode and decode messages “effortlessly”. Or how else are we going to send secure messages in the future?

In plain words
The 3D Printed Binary Enigma is a manually operated encryption device inspired by WWII Enigma machines. It requires no batteries and allows users to encode and decode messages by hand. The device is designed for anyone seeking a physical alternative to digital encryption, combining mechanical operation with binary-based encoding for offline message security.

I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it…
Enigma Machine and Bombe Implemented in eBPF – Turing's 113th Birthday2025 · github.com · ▲5I implemented the Enigma encryption machine and Bombe decryption device in eBPF to honor Alan Turing's legacy. This project uses eBPF to process network packets through virtual Enigma rotors and reflectors, just like the original WWII-era machines. Messages sent through virtual interfaces are not only encrypted but also decrypted in real-time, demonstrating how Turing's pioneering work can be reimagined with modern systems programming. The implementation includes configurable rotors, reflectors, and position settings.
