As long as we can communicate securely, everything will be fine. In this talk I will present how one can build an entire decentralised and distributed encrypted network to carry data, voice, text and more - all based on the sanctum project I presented at SEC-t last year. From peer-to-peer and end-to-end encrypted tunnels between laptops, desktops and phones to full on group voice-calls and chatting between these devices, using only sanctum and its underlying protocol. I will deep dive into said protocol, how it works, what the tradeoffs are and how to put this up yourself in a safe and secure way. So put on your hacker hat, and let's hack.
