Products that do what P2Party – Encrypted WebRTC Room URLs does

Hi HN, I’ve been working for the past 10 months on p2party, a TypeScript/C/WASM library which you can find at https://github.com/p2party/p2party-js and demo at https://p2party.com , that lets you spin up an encrypted peer-to-peer mesh with nothing more than a shared URL. Why I built it: I wanted something between https://file.pizza and “ephemeral Signal chat”, but with my custom cryptographic idea (I know I know... WebRTC is already encrypted and it is easy to go wrong etc.). The project started as a toy for sharing large DAW files with my…

    Hi HN, This is a site where users can submit content and the shortest SHA256 value of nonce+content among them will make the site display the content. Very basic, without a blockchain. It's a static site with WebRTC and peer-to-peer. Why? I wanted r/place (Reddit canvas where users collaborate on a pixel grid), but with proof of work. This is my progress so far. It's a WebRTC app with peer to peer connectivity that forwards the best hashed values to other users, which verify them, display them and pass them on. There are many many improvements to be done (especially I should probably…

    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…

    Hey HN! I just released weron, a P2P VPN that uses WebRTC for transport which I've been working on for the last couple of months. It can create both layer 2/Ethernet and layer 3/IP overlay networks, and the underlying transport layer can be easily embedded to write your own P2P apps with Go. Compared to for example Tailscale, WireGuard and ZeroTier, its much harder to block on a network level and also significantly easier to set up, while not sacrifing much performance. I'd love to get your feedback :)

    From the cryptic terminal commands to the innumerable ways to shoot yourself in the foot, I always struggled to use TLS certificates. I love how much easier (and cheaper) Let's Encrypt made it to get certificates, but there are still plenty of things to struggle with. That's why we built Relay: a free, browser-based tool that streamlines the ACME workflow, especially for tricky setups like homelabs. Relay acts as a secure intermediary between your ACME client and public certificate authorities like Let's Encrypt. Some ways Relay provides a better experience: - really fast, streamlined…

    Hello HN. I am excited to share with you my new book, Bulletproof TLS and PKI. I've worked in this space since the very early days (think SSLv2), always frustrated with the fact that the field is vast but the documentation poor. That first led me to create SSL Labs (which ended up being very popular) and then the first edition of my book (in 2014), where I aimed to cover everything a curious person needed to know about SSL/TLS and PKI. Most importantly, it's a very practical book that you can use to just learn what you need at that moment. The second edition (just out) adds coverage of…

    Still very much a work in progress, but really wanted to share this even in it's early state. Had heaps of fun building it to learn more about WebRTC.

    I have decided to open source this project to increase trust even further. In case you have seen my previous posts, this is an update for berb.app, a WebRTC file sharing app. My goal is simple: send files between devices in real-time without installing crap or uploading to any servers.

    Made this to use my laptop terminal session on mobile without data going through a server. tt start -p mypassword → get a URL (qrcode) → open in browser → enter password → connected. Direct webrtc datachannel between your machine and browser. Signaling server is a cloudflare worker, exchanges ~2KB of sdp/ice metadata then gets out of the way. Password never transmitted - argon2id derives 256-bit key locally on both ends. All terminal i/o gets nacl secretbox encryption before hitting the datachannel. double encrypted with dtls underneath but I wanted the relay to see nothing useful…

    I built SecureShare to solve a common problem I faced: securely sharing files between devices without size limits or intermediary servers. What it does: - Direct P2P file/text/folder sharing using WebRTC - No file size limits (only constrained by local disk space) - No registration required - All data stays on your devices (no server storage) - Supports multiple simultaneous receivers - Custom retrieval IDs and QR codes for easy sharing - Works across platforms, mobile-optimized Technical details: - Built with Next.js + Tailwind + shadcn/ui - Backend: Node.js + Redis (minimal,…

    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 :)

    Hi everyone, I built a runtime to isolate untrusted code using wasm sandboxes. Basically, it protects your host system from problems that untrusted code can cause. We’ve had a great discussion about sandboxing in Python lately that elaborates a bit more on the problem [1]. In TypeScript, wasm integration is even more natural thanks to the close proximity between both ecosystems. The core is built in Rust. On top of that, I use WASI 0.2 via wasmtime and the component model, along with custom SDKs that keep things as idiomatic as possible. For example, in Python we have a simple decorator:…

    I’d like to share a open source project I’ve been working on: Weblink, a pure web-based file transfer and chat application built on WebRTC. No downloads or installations are needed—everything works directly in your browser. Key features include: - Works seamlessly as a PWA for sharing files/text through the system - File synchronization and resuming interrupted transfers - Video calling - Clipboard and folder transfer (folders are auto-compressed) Weblink uses a serverless P2P architecture, supporting multiple backends like Firebase and self-hosted WebSocket, and ensures signaling…

    Hi HN, I built [PinSend](https://pinsend.app) — a free web app for instantly sharing text between devices, using a simple 6-character PIN. - No login, no account, no install. - Peer-to-peer WebRTC transfer (no server relay, no cloud). - Cross-platform: works on any modern browser. I built PinSend for myself while developing web apps—I was always copying ngrok links and sending error logs between my laptop and mobile devices. I wanted a frictionless, instant way to move links and text between anything. *Demo:* 1. Open https://pinsend.app on your phone & laptop 2. Paste or…
