Synchronize clipboard between computers

The project consists of 2 parts, a server that is responsible for passing messages between client and the client which interact with the clipboard on the machine.

Simply run the server executable to start the server, by default the server listens on port 80, this can be changed by setting the PORT environment variable.

A pre-built docker image with the server is available as clipboardsync/server and a static binary is available in the releases page.

The server is currently only tested on linux, but should run on all platforms with proper rust support.

When running the client, you need to specify the websocket address of the server and the session identifier to use, all clients that share a session identifier will have their clipboards synced.

client ws://example.com my_session_key

The client is currently tested on linux(X11) and windows, but should also work fine on OSX and BSD. Prebuild binaries for windows can be found on the releases page.

clipboard-sync is build using rust and can be build using a simple

cargo build --release

which will put the server and client binary in target/release.

If multiple users have access to the machine running the clipboard-sync server it's important to take care about security to prevent other users from snooping the clipboard contents.

• Put the sync server behind an SSL proxy

  This prevents the clipboard contents from being send over the network unencrypted.
  Note that using ssl on windows is currently broken, the clipboard-sync should thus only be used in secure environments when windows support is required.

• Use a secure session key

  Everyone that knows the session key and has access to the sync server will be able to read the sync traffic. Picking a secure random key will prevent snooping of clipboard contents.
