24 alternatives to 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?
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made a binary enigma machine for manual encryption launched in 2024; newer entries below may have overtaken it.

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…

I 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.

The core question: how did HP's scientific calculators actually work at the gate level? That rabbit hole led to building one from scratch. The architectural decision everything else follows from: a decimal calculator should store numbers as BCD — one decimal digit per 4-bit nibble. A standard byte-oriented CPU (Z80, 6502) fights that layout constantly. So I designed a small custom CPU in Verilog where 4 bits is the natural data width and memory is nibble addressable. What the project covers: - Custom CPU: Harvard architecture, 12-bit ISA, 8-state execution FSM, hardware stack guard with a…

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 +…

Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

Good morning HN! For a while now I have been toying with this idea and now finally have a working prototype. This project allows you to encode secret messages into ordinary looking text by using arithmetic coding with a probability model derived from an LLM. By encrypting the message and then decompressing the encrypted message using the arithmetic coder, you get output which looks just like randomly sampled output from the LLM. Except, it actually encodes your secret messages in the specific choices of tokens. By using authenticated encryption, only a user who knows the key can know that a…
