Products that do what Wormhole.page – Magic Wormhole file transfer in the browser via WASM does
Magic Wormhole is great but requires a CLI or app. I put a full wormhole-rs client in the browser via WebAssembly so you can send E2E encrypted files to anyone — interoperable with all standard wormhole CLIs. Drop a file, get a code, other person opens the link or types wormhole-rs receive . SPAKE2 + NaCl encryption happens client-side, the server only bridges WebSocket transit. Built this as an experiment with Claude Code + gstack. All code written by Claude. Single Rust binary, vanilla JS, no framework. https://wormhole.page…

My weekend project sendenv is a CLI tool that lets you share environment variables securely with someone else. It is built on top of magic-wormhole which allows for safe, account-free data transfer. When you send variables using sendenv, it creates a one-time code. You give this code to the person who needs the variables. They use the code in their shell to load the variables. This is handy for quickly setting up new team members or copying local environment variables to another system. Its currently in alpha obviously, but the core functionality works (I have tested sending vaults from a…

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:…

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…

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 HN. I built Payload to make file transfers easy for less-technical users who need large/fast transfers, so I have focused on auto-discovery, drag-and-drop, visually distinct device icons. It's using Tauri (an "Electron alternative" built on Rust) which keeps my binaries small and bundles to .msi, .dmg, .deb and .appimage. No CLI, iOS or Android support (yet). The network stack is a separate binary written in Go. It uses mDNS for local network discovery and TLS over TCP or Quic, with a public Ed25519 keypair for each device. The protocol is ad-hoc and symmetrical control stream using…

Capsule started as a basic HTTP server to teach myself Rust. Then I kept going, and it turned into the first full-stack thing I've fully shipped: a Rust/Axum server, a Rust CLI, an Android app (my first, same story as the Rust one), and a fully featured web UI. It quickly grew as I realized I could solve my file transfer problem by turning a basic webserver into an actual daily use tool. Entire project is open source, code can be found at: https://github.com/withcapsule/ Would love to hear anyone's thoughts on this.

Hey HN, At work, I was annoyed about having to download logs by writing them out to files and transferring them over to my local over HTTP (admittedly, this is because of a rather novel architectural situation). So, I built a tool in Go that lets you pipe contents into an SSH server for sending and reading them out on another connection. You can also use this tool to transfer files. Just cat the file on the sender end and redirect the output of the receiver end to a file. Please note that the transfer rate is heavily dependent on your connection and proximity to the public ssh.beam.camp…

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…
