On: TLS Everywhere, not https: URIs (2015)

In the context of sharing public keys, I'd say you merely need authentication. Web of Trust being one possible mechanism. This isn't a particularly advanced topic.

Relevant to my original post, information about whether the connection should be encrypted also merely needs to be authenticated, not encrypted itself. Of course, the HSTS preloading site uses HTTPS (with encryption) because it's easy and why not.

Thanks. So re keysharing, authentication is a form of secure channel.

I'm reading the auth and channel as independent. Auth is something of a metachannel, perhaps.

Fair enough. :)
