Dropwire: end-to-end encrypted, no-account P2P file transfer built on iroh (alpha)

[muhamadjawdatsalemalakoum]

I built Dropwire, a free and open-source desktop app for sending files directly
device-to-device on top of iroh 1.0. Sharing it here because the iroh stack is what
made it feasible and I'd love feedback from people who know the internals.

What it does:

• Direct P2P transfer; when a direct path can't be established it falls back to an
  encrypted relay that can't read the bytes (end-to-end encrypted).
• No account, no sign-up, no cloud middleman. You pair with a one-time code or QR.
• Preview-before-accept: the receiver sees file names/sizes/count and can selectively
  download before anything lands on disk.
• Resumable transfers. Cross-platform: Windows, macOS, Linux.

Stack: Rust core with iroh 1.0 for networking, Tauri v2 for the shell. Relay and DNS
are self-hostable, so you don't have to depend on anyone's infrastructure.

Honest status: it's ALPHA and built solo, so expect rough edges. The installers are
not code-signed yet, so Windows/macOS will show an unknown-publisher warning — that's
expected for now, and the source + build instructions are public so you can build it
yourself. Licensed MIT OR Apache-2.0.

Feedback, bug reports, and brutal honesty on the networking design are all welcome.
