Struct RopePacket 

pub struct RopePacket {
    pub step: RopeStep,
    pub inner: KkPacket,
}

An encrypted message with forward secrecy.

Contains the ratchet step metadata (so the receiver can derive the same message key) and the inner KkPacket (the actual encrypted payload, which carries its own entropy snapshot and integrity commitment).

Double entropy: the ratchet step uses one EntropySnapshot for key derivation, and the inner KkPacket captures its own independent snapshot for per-symbol encryption. Two unrepeatable moments per message.

Wire Format

[8-byte counter][48-byte ratchet snapshot][inner KkPacket bytes...]

Fields

step: RopeStep

Ratchet step metadata (counter + entropy snapshot).

inner: KkPacket

The inner encrypted packet, keyed by the ratchet’s message key.

Implementations

impl RopePacket

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

pub fn from_bytes(data: &[u8]) -> Result<Self>

Deserialize a forward-secret packet from received bytes.

Trait Implementations

impl Clone for RopePacket

fn clone(&self) -> RopePacket

Returns a duplicate of the value.

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