Struct NoiseChannel 

pub struct NoiseChannel { /* private fields */ }

Real Noise Protocol encrypted channel using snow.

Performs a Noise XX handshake over the underlying MeshStream, then encrypts/decrypts all subsequent messages using the established session keys. Uses Noise_XX_25519_ChaChaPoly_SHA256.

Implementations

impl NoiseChannel

pub fn handshake_hash(&self) -> &[u8]

The session’s Noise handshake hash (32 bytes for SHA-256). Equal on both ends of one session, different on every other session.

pub async fn initiate( stream: Box<dyn MeshStream>, config: &NoiseConfig, ) -> Result<Self, MeshError>

Perform a Noise XX handshake as the initiator and return an encrypted channel.

pub async fn respond( stream: Box<dyn MeshStream>, config: &NoiseConfig, ) -> Result<Self, MeshError>

Perform a Noise XX handshake as the responder and return an encrypted channel.

Trait Implementations

impl EncryptedChannel for NoiseChannel

fn send_encrypted<'life0, 'life1, 'async_trait>( &'life0 mut self, plaintext: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<(), MeshError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Send encrypted data (plaintext in, ciphertext on the wire).

fn recv_encrypted<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, MeshError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Receive and decrypt data (ciphertext from wire, plaintext out).

fn remote_static_key(&self) -> Option<&[u8]>

Get the remote peer’s static public key (after handshake).

fn handshake_hash(&self) -> Option<&[u8]>

The Noise handshake hash of this session, when the channel has one. Both sides of a session compute the same value; admission signs it to bind a node identity to this exact session (P3-K1). None for channels without a handshake (plaintext passthrough).

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<(), MeshError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Close the encrypted channel gracefully.
