How to accept multiple public keys?

[vifino]

Hey.
I've been wondering how to properly accept multiple public keys instead of just a single one.
Does simply not providing a remote_public_key(&pubkey) and checking HandshakeState.get_remote_static() work?
Using a psk works, but it's not ideal.

It could be really useful to check against a list of allowed public keys instead of just allowing a single one. I think simply not providing a remote_public_key and checking HandshakeState.get_remote_static() should work.

@vifino sorry for not getting back to you. @zserik is correct - using the X pattern (static key for sender is transmitted) will allow you to receive a static key and then verify it in whatever way you'd like.
