Struct SessionMsg3 

pub struct SessionMsg3 {
    pub flags: u8,
    pub handshake_payload: Vec<u8>,
}

XK handshake message 3 (initiator -> responder).

Carries the initiator’s encrypted static key and epoch. Sent by the initiator after receiving msg2. The responder learns the initiator’s identity from this message.

Wire Format

Offset	Field	Size	Description
0	flags	1 byte	Reserved
1	handshake_len	2 bytes	u16 LE, Noise payload length
3	handshake_payload	variable	Noise XK msg3 (73 bytes typical)

Fields

flags: u8

Reserved flags byte.

handshake_payload: Vec<u8>

Noise XK handshake message 3.

Implementations

impl SessionMsg3

pub fn new(handshake_payload: Vec<u8>) -> Self

Create a new SessionMsg3 with the given handshake payload.

pub fn encode(&self) -> Vec<u8>

Encode as wire format (4-byte FSP prefix + flags + handshake).

The 4-byte prefix: [ver_phase:1][flags:1][payload_len:2 LE] where ver_phase = 0x03 (version 0, phase MSG3).

pub fn decode(payload: &[u8]) -> Result<Self, ProtocolError>

Decode from wire format (after 4-byte FSP prefix has been consumed).

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

Performs copy-assignment from source.

impl Debug for SessionMsg3

fn fmt(&self, f: &mut Formatter<'_>) -> Result
