Is such communication channel secure and how to verify the authenticity of the remote device? It seems that since Bluetooth 2.1 encryption is mandatory, according to Wikipedia.

How to do the reverse, like share secrets over Bluetooth from Android to Linux? What about between Android to Android? There is NFC in the latter case but not on the relative phone I have in mind:

Wifi hotspot with HTTP server can be a workaround or even clipboard access thanks to wifi hotspot and possible SSH proxy.
