If I pair my Android phone and my laptop, I can share files over Bluetooth from the phone to the laptop. I’ve started finding this a really convenient method for me to send files to a Linux laptop without needing to install a separate app on either the phone or my laptop. Especially when I’m away from my home network (I use SFTP at home).

How secure is this? Is there encryption by default and could someone else nearby with a receiver potentially decode the file you’re sending?

    No, thanks:

    It uses a WebRTC peer-to-peer connection. WebRTC needs a signaling server that is only used to establish a connection. The server is not involved in the file transfer.

    If your devices are paired and behind a NAT, the PairDrop TURN Server is used to route your files and messages.
