I've been working with this multi-threaded SSH server that I made and I've encountered an issue. I need a way to get the credentials each channel used for authentication. For example, in handle after I accept a channel from the transport, I'd like to know what credentials that channel used to authenticate itself to the server, something like channel.get_credentials() -> (username, password). Reading the docs, I couldn't find a way, but hopefully someone out there knows something I don't.
