Flagging a NetworkPeer as 'secure'

[Veritius]

It could be good to be able to mark a NetworkPeer as being "secure", and messages sent to them can be trusted to be invulnerable to MITM attacks. Though, encryption and authentication are distinct, so maybe there should be different tiers of security.

Something like this

enum PeerSecurity {
    Unprotected,
    Encrypted,
    Authenticated,
}
