An easy way to share clipboard (encrypted by Blowfish) on a LAN.
Make a $HOME/.copy-paste-sync.pass with a large randomly generated
password in it on both machines.
For two machines, 192.168.8.1 (macOS) and 192.168.8.2 (Linux), run the following:
Run on macOS:
$ stack run -- macos 3232 http://192.168.8.1:3232 $HOME/copy-paste-sync.pass
Run on Linux:
$ stack run -- linux 3232 http://192.168.8.2:3232 $HOME/copy-paste-sync.pass
