Function libp2p::noise::handshake::rt15_responder

Important traits for Handshake<T, C>

impl<T, C> Future for Handshake<T, C> type Output = Result<(RemoteIdentity<C>, NoiseOutput<T>), NoiseError>;

pub fn rt15_responder<T, C>(
    io: T, 
    session: Result<HandshakeState, NoiseError>, 
    identity: KeypairIdentity, 
    identity_x: IdentityExchange
) -> Handshake<T, C> where

    T: AsyncWrite + AsyncRead + Unpin + Send + 'static, 

Creates an authenticated Noise handshake for the responder of a 1.5-roundtrip (3 message) handshake pattern.

Subject to the chosen [IdentityExchange], this message sequence identifies the local node in the second message payload and expects the remote to identify itself in the third message payload. The first (unencrypted) message payload is always empty.

This message sequence is suitable for authenticated 3-message Noise handshake patterns where the static keys of the responder and initiator are either known (i.e. appear in the pre-message pattern) or are sent with the second and third message, respectively (e.g. XX).

initiator --{}--> responder
initiator <-{id}- responder
initiator -{id}-> responder
