Have been following this project for a while, cool stuff!

I work a bunch with vpn-like networking on Android phones and it would be cool to have a bit of info on how I might get something like working on phones. I guess its probably not your typical usecase.

Currently since the project is a VPN client, I already intercept all of the packets, I have a pcap writer and can write to files or a tcp sockets and connect wireshark to it - but it needs a bunch of complication to setup the keys so that I can see through encryption, so anything that would make that process easier would be great.

I'm curious what your product does

I've seen that type of behavior for apps that inject ads and add affiliate marketing links

Its an internet sharing app that uses Wi-Fi direct and BLE

The wireshark stuff is only for when I'm debugging

That sounds like a hotspot with extra steps, what does it do differently?

It can do multi-hop. It can also automatically authenticate across any number of phones, sort of like how radius works with fixed wifi (android hotspots don't support radius - you can only connect with radius as a client). You can also earn money from sharing your internet.
