Authentication example

[bgokden]

Hello, I am looking for an example where two nodes authenticate with a pre-shared key.
Is it possible or should I add a new extension?

It is not possible just yet to authenticate with a pre-shared key, though exposing the option to provide a pre-shared key should be straightforward. It would involve modifying the handshake function in client.go.

However, I currently am busy right now with other projects, unfortunately. I will only be able to integrate in this option around next week. However, if you need it and able are to tackle it now, I would appreciate a PR! Happy to help out should that be the case too :).

any update on this? we're starting a project with Noise and just identified a need for this today, to prevent a "poisoned peer" situation where anyone running the noise protocol could attempt to talk to your peer network.

@haukened I actually don't have a working solution for this. I have thought of two solutions.
The first one was editing the first message exchange.
The second one was adding a new protocol that looked nicer solution, but I couldn't finish it and I am not working on it anymore.

Thanks for the update bgkoden. i think adding a protocol might be what i need here! I'll likely extend gossip to have a PSK field.

@haukened What did you end up doing? I am working on something with a similar need.
