Syncthing

File synchronization based on syncthing.

Syncthing is an open-source file synchronization client/server application, written in Go, implementing its own, equally free Block Exchange Protocol. All transit communications between syncthing nodes are encrypted using TLS, and all nodes are uniquely identified with cryptographic certificates.
