They’re encrypted with a PSK encrypted with either AES128 or AES256. It’s built into the Meshtastic firmware so that’s not something I have to handle directly, thankfully!

I started thinking about using the LoRa protocol directly for this too! My biggest concern is overwhelming the mesh. But I also had no idea what protocol would work so thanks for mentioning PPP. I haven’t thought about that since I was a kid! That would be really cool though!

Maybe just for a POC someday?

Also: how are you liking MeshCore? Did you have to pay for a license to use it? How expensive is the mesh you’re building? That is something I’ve started thinking about too for this exact reason 😂

Sadly no I’m not, but I was very inspired by him when I was in that scene! PSP hacking was my first experience with customizing any kind of device beyond what average users can do and it’s what made me fall in love with computers as a kid. I don’t think I’d be the software engineer I am today or even in this field if it wasn’t for him. My name is Alex so I thought I could pay homage to him by choosing a similar username, since he had such a massive impact on my life ☺️
