Struct NoiseConfig

Source 
pub struct NoiseConfig { /* private fields */ }
Expand description

A key holder structure used for both initiators and responders.

Implementations§

Source§

impl NoiseConfig

Source

pub fn new(private_key: PrivateKey) -> Self

A peer must create a NoiseConfig through this function before being able to connect with other peers.

Source

pub fn public_key(&self) -> PublicKey

Handy getter to access the configuration’s public key

Source

pub fn initiate_connection( &self, rng: &mut (impl RngCore + CryptoRng), prologue: &[u8], remote_public: PublicKey, payload: Option<&[u8]>, response_buffer: &mut [u8], ) -> Result<InitiatorHandshakeState, NoiseError>

An initiator can use this function to initiate a handshake with a known responder.

Source

pub fn finalize_connection( &self, handshake_state: InitiatorHandshakeState, received_message: &[u8], ) -> Result<(Vec<u8>, NoiseSession), NoiseError>

A client can call this to finalize a connection, after receiving an answer from a server.

Source

pub fn parse_client_init_message( &self, prologue: &[u8], received_message: &[u8], ) -> Result<(PublicKey, ResponderHandshakeState, Vec<u8>), NoiseError>

A responder can accept a connection by first parsing an initiator message. The function respond_to_client is usually called after this to respond to the initiator.

Source

pub fn respond_to_client( &self, rng: &mut (impl RngCore + CryptoRng), handshake_state: ResponderHandshakeState, payload: Option<&[u8]>, response_buffer: &mut [u8], ) -> Result<NoiseSession, NoiseError>

A responder can respond to an initiator by calling this function with the state obtained, after calling parse_client_init_message

Source

pub fn respond_to_client_and_finalize( &self, rng: &mut (impl RngCore + CryptoRng), prologue: &[u8], received_message: &[u8], payload: Option<&[u8]>, response_buffer: &mut [u8], ) -> Result<(Vec<u8>, NoiseSession), NoiseError>

This function is a one-call that replaces calling the two functions parse_client_init_message and respond_to_client consecutively
