Struct PqSuite 

pub struct PqSuite { /* private fields */ }

The post-quantum suite: a per-session ChaCha20-Poly1305 key (from an ML-KEM-768 handshake, see pq_handshake_initiator / pq_handshake_responder). Each seal_body draws a fresh counter nonce, so every frame is unique; the nonce is carried in the body, so the peer opens statelessly. The suite id is bound as the AEAD associated data, so a frame can’t be replayed under a different suite. (Bidirectional use derives a key per direction — see the handshake.)

Implementations

impl PqSuite

pub fn new(key: [u8; 32]) -> Self

A PQ suite over an already-derived 32-byte AEAD key.

Trait Implementations

impl Suite for PqSuite

fn id(&self) -> u16

The wire suite id bound into the envelope header.

fn seal_body(&self, blob: &[u8]) -> Vec<u8>

Transform an opaque blob into the envelope body — identity for null; for a real suite, handshake/sequence ‖ AEAD(blob)+tag.

fn open_body(&self, body: &[u8]) -> Option<Vec<u8>>

Reverse Suite::seal_body, or None on a tampered / malformed body.
