This combines the cryptography of Magic Wormhole (via Fowl) and the terminal-sharing of tty-share into a secure, end-to-end encrypted, peer-to-peer terminal sharing application.
You are now sharing a single terminal running on “host”. Beware: the guest can type, run commands, etc. so only do this with humans you would hand your local keyboard over to.
Once thetwo things happen (i.e. “shwim” on the host and “shwim ” on the guest), there is a secure tunnel between both computers. The host will decide a random port and run tty-share as a server; the guest will run tty-share as a client.
On both computers, tty-share will be running as a subprocess with correct options to do networking via Magic Wormhole only. All raw-mode terminal I/O is forwarded to this tty-share process so things like curses etc work as expected.
Once either side exits, the networking forwarding is done – there is no long-term credential sharing or any other network set preserved or altered on the “host” nor “guest” computers.
