Hi, creator here. This is a demo of our recent work presented at Oakland (IEEE S&P): https://eprint.iacr.org/2022/368. The server and client code are written in Rust and available here: https://github.com/menonsamir/spiral-rs. The general aim of our work is to show that homomorphic encryption is practical today for real-world applications. The server we use to serve this costs $35/month! A quick overview: the client uses homomorphic encryption to encrypt the article number that they would like to retrieve. The server processes the query and…

We launched Hackerest last week. We’re a group of security engineers based in Italy (ex-Amazon, Accenture) who spent years doing pentests the traditional way and kept wondering why the workflow still looks like it did in 2010. Most pentests today (still) work like this: 1. the engagement runs for days or weeks 2. nothing is shared until everything is finished 3. the client gets a PDF long after the issues were actually discovered 4. half of the attack surface has changed by then What Hackerest does: * findings appear in real time during the active testing window, as testers discover them *…

Enc is a CLI tool for encryption, a modern and friendly alternative to GnuPG. It is easy to use, secure by default and can encrypt and decrypt files using password or encryption keys, manage and download keys, and sign data. Our goal was to make encryption available to all engineers without the need to learn a lot of new words, concepts, and commands. It is the most beginner-friendly CLI tool for encryption, and keeping it that way is our top priority.

Hello HN, we're CipherNomad, the research initiative behind this project. The Ariadne Protocol is our exploration of a different cryptographic model. The work began with an observation of primitives like the Lion transform, which use a static, hardcoded sequence of operations. This led us to ask: What if the cryptographic "program" wasn't a constant, but a dynamic, history-dependent variable? Our first step was a "Cryptographic Virtual Machine" that took an explicit list of operations (a "Path"). This worked, but required sharing the Path object—an explicit dependency that needed to be…

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 :)

hey folks! My book Real-World Cryptography was just released and is now shipping. I've been working on this thing for the last two years and a half, and the goal was to give a good overview of everything that can be classified as "real-world" about crypto. You'll find all the basics in the first half of the book, and the second half contains chapters on TLS, noise, PAKEs, post-quantum cryptography, zero-knowledge proofs, MPC, cryptocurrencies, FHE, etc. So it's a good pick if you're learning, but also if you've been in the field for a while and want an intro to some subfield you're…

Hey Hacker News, I’m excited to introduce ClassroomIO – a project that I’ve been working on for the past few months. It’s an educational platform that provides an in-browser code editor and execution environment. The idea is to make teaching programming easier by eliminating the technical barriers that educators and students often face. Feature highlights: * In-Browser coding: Write, run, and debug code directly in your browser. No more downloading software, configuring environments, and resolving compatibility issues. * Course management: Manage classes, assignments, and student…
