I don't really like how you're reusing MessageState in all of these requests. Prefer to create new structs for each call, mirroring the underlying API.

Why not reuse the struct if the all end up just being a pair of byte vecs? To perserve the typedness of the API. If you have one type of like a ServerRegistrationStartResult there's really only one thing you can do with it -- the next step in the protocol. This is good API design because its hard to misuse.

nit: I wouldn't have introduced password_file_bytes. Just file: s.serialize().

Also consider inlining the message: s.message.serialize()? here

Why does this function exist?

I'd inline this also
