WASM port of wormhole-rs brings SPAKE2 encryption to browsers without server storage.

Strengths
  • •Full wormhole-rs client in WASM maintains interoperability with existing CLI tools
  • •SPAKE2 + NaCl encryption happens entirely client-side, server only bridges WebSocket
  • •Single Rust binary with vanilla JS means no framework dependencies or build pipeline
Weaknesses
  • •Magic Wormhole CLI already exists; browser convenience doesn't solve new problem
  • •WebRTC-based alternatives like Sharedrop and Snapdrop already handle browser P2P

Post Description

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 <code>. 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.
