Struct libp2p_noise::NoiseConfig

pub struct NoiseConfig<P, C: Zeroize, R = ()> { /* private fields */ }

👎Deprecated: Use libp2p_noise::Config instead. All other handshake patterns are deprecated and will be removed.

The protocol upgrade configuration.

Implementations

impl<H, C: Zeroize, R> NoiseConfig<H, C, R>

pub fn into_authenticated(self) -> NoiseAuthenticated<H, C, R>

Turn the NoiseConfig into an authenticated upgrade for use with a Swarm.

pub fn with_prologue(self, prologue: Vec<u8>) -> Self

Set the noise prologue.

pub fn set_legacy_config(&mut self, cfg: LegacyConfig) -> &mut Self

👎Deprecated since 0.42.0: LegacyConfig will be removed without replacement.

Sets the legacy configuration options to use, if any.

impl<C> NoiseConfig<IX, C>where C: Protocol<C> + Zeroize,

pub fn ix(dh_keys: AuthenticKeypair<C>) -> Self

Create a new NoiseConfig for the IX handshake pattern.

impl<C> NoiseConfig<XX, C>where C: Protocol<C> + Zeroize,

pub fn xx(dh_keys: AuthenticKeypair<C>) -> Self

Create a new NoiseConfig for the XX handshake pattern.

impl<C> NoiseConfig<IK, C>where C: Protocol<C> + Zeroize,

pub fn ik_listener(dh_keys: AuthenticKeypair<C>) -> Self

Create a new NoiseConfig for the IK handshake pattern (recipient side).

Since the identity of the local node is known to the remote, this configuration does not transmit a static DH public key or public identity key to the remote.

impl<C> NoiseConfig<IK, C, (PublicKey<C>, PublicKey)>where C: Protocol<C> + Zeroize + AsRef<[u8]>,

pub fn ik_dialer( dh_keys: AuthenticKeypair<C>, remote_id: PublicKey, remote_dh: PublicKey<C> ) -> Self

Create a new NoiseConfig for the IK handshake pattern (initiator side).

In this configuration, the remote identity is known to the local node, but the local node still needs to transmit its own public identity.

Trait Implementations

impl<P: Clone, C: Clone + Zeroize, R: Clone> Clone for NoiseConfig<P, C, R>

fn clone(&self) -> NoiseConfig<P, C, R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, C> InboundUpgrade<T> for NoiseConfig<IK, C>where NoiseConfig<IK, C>: UpgradeInfo, T: AsyncRead + AsyncWrite + Unpin + Send + 'static, C: Protocol<C> + AsRef<[u8]> + Zeroize + Clone + Send + 'static,

Implements the responder part of the IK handshake pattern.

IK is a single round-trip (2 messages) handshake.

In the IK handshake, the initiator is expected to know the responder’s identity already, which is why the responder does not send it in the second message.

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

type Output = (RemoteIdentity<C>, Output<T>)

Output after the upgrade has been successfully negotiated and the handshake performed.

type Error = Error

Possible error during the handshake.

type Future = Pin<Box<dyn Future<Output = Result<(RemoteIdentity<C>, Output<T>), Error>> + Send + 'static, Global>>

Future that performs the handshake with the remote.

fn upgrade_inbound(self, socket: T, _: Self::Info) -> Self::Future

After we have determined that the remote supports one of the protocols we support, this method is called to start the handshake.

impl<T, C> InboundUpgrade<T> for NoiseConfig<IX, C>where NoiseConfig<IX, C>: UpgradeInfo, T: AsyncRead + AsyncWrite + Unpin + Send + 'static, C: Protocol<C> + AsRef<[u8]> + Zeroize + Clone + Send + 'static,

Implements the responder part of the IX noise handshake pattern.

IX is a single round-trip (2 messages) handshake in which each party sends their identity over to the other party.

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

type Output = (RemoteIdentity<C>, Output<T>)

Output after the upgrade has been successfully negotiated and the handshake performed.

type Error = Error

Possible error during the handshake.

type Future = Pin<Box<dyn Future<Output = Result<(RemoteIdentity<C>, Output<T>), Error>> + Send + 'static, Global>>

Future that performs the handshake with the remote.

fn upgrade_inbound(self, socket: T, _: Self::Info) -> Self::Future

After we have determined that the remote supports one of the protocols we support, this method is called to start the handshake.

impl<T, C> InboundUpgrade<T> for NoiseConfig<XX, C>where NoiseConfig<XX, C>: UpgradeInfo, T: AsyncRead + AsyncWrite + Unpin + Send + 'static, C: Protocol<C> + AsRef<[u8]> + Zeroize + Clone + Send + 'static,

Implements the responder part of the XX noise handshake pattern.

XX is a 1.5 round-trip (3 messages) handshake. The first message in a noise handshake is unencrypted. In the XX handshake pattern, that message is empty and thus does not leak any information. The identities are then exchanged in the second and third message.

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

type Output = (RemoteIdentity<C>, Output<T>)

Output after the upgrade has been successfully negotiated and the handshake performed.

type Error = Error

Possible error during the handshake.

type Future = Pin<Box<dyn Future<Output = Result<(RemoteIdentity<C>, Output<T>), Error>> + Send + 'static, Global>>

Future that performs the handshake with the remote.

fn upgrade_inbound(self, socket: T, _: Self::Info) -> Self::Future

After we have determined that the remote supports one of the protocols we support, this method is called to start the handshake.

impl<T, C> OutboundUpgrade<T> for NoiseConfig<IK, C, (PublicKey<C>, PublicKey)>where NoiseConfig<IK, C, (PublicKey<C>, PublicKey)>: UpgradeInfo, T: AsyncRead + AsyncWrite + Unpin + Send + 'static, C: Protocol<C> + AsRef<[u8]> + Zeroize + Clone + Send + 'static,

Implements the initiator part of the IK handshake pattern.

IK is a single round-trip (2 messages) handshake.

In the IK handshake, the initiator knows and pre-configures the remote’s identity in the HandshakeState.

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

type Output = (RemoteIdentity<C>, Output<T>)

Output after the upgrade has been successfully negotiated and the handshake performed.

type Error = Error

Possible error during the handshake.

type Future = Pin<Box<dyn Future<Output = Result<(RemoteIdentity<C>, Output<T>), Error>> + Send + 'static, Global>>

Future that performs the handshake with the remote.

fn upgrade_outbound(self, socket: T, _: Self::Info) -> Self::Future
