On “Modern Alternatives to PGP”
According to parents nice talk1 you can add a verify switch that lets you compare the signature of the actual key. So a public authenticated channel is enough. 1 link to this video

Brian Warner explains the design, cryptography, and usage of magic-wormhole, a tool for secure and simple file transfers between computers.
"Speaker: Brian Warner ""magic-wormhole"" is a simple tool to move files from one computer to another, like ""scp"" but without the setup. By telling the recipient just a few secret words, the file is safely encrypted and delivered directly to the correct machine. The talk will explain the security mechanics, the cryptography (NaCl and SPAKE2), and how to use the underlying open-source library in your own applications. Slides can be found at: speakerdeck.com/pycon2016 and github.com/PyCon/2016-slides"Why it's here
3 people recommend thisWhat people say. Recommended as an excellent explanation of the SPAKE2 cryptography and design behind the magic-wormhole file transfer tool.

On “OpenDrop: An Open Source AirDrop Implementation”
Have you taken a look at magic-wormhole1? I've started using it recently and it's insanely easy to use. It does have a centralised signalling server for key exchange between peers, but it does attempt to do peer-to-peer data transfer (only falling back to a TURN-style relay if both clients are behind NATs and aren't on the same local network). An explanation of the cryptography and design was given at PyCon 20162. It also has built-in optional Tor support (though I'm not sure if it attempts to use an onion service for data transfer). 1: link 2: link to this video
