Assume this is public because is used above (Protocol.key_challenge). In that case, perhaps will be better add a :nodoc: marker to avoid this showing up in the documentation?

Yes, this needs to be accessible from WebSocketHandler.
The entire Protocol class is just internal implementation and not documented.

Let's have WebSocket::Protocol::VERSION_STRING too, or something like that. I'd like to avoid a to_s call for each socket upgrade.

Good catch 👍 It's only used as a string anyway, so I'll just change the datatype of the constant.
