Struct HybridKeyExchange 

pub struct HybridKeyExchange {
    pub classical_secret: Vec<u8>,
    pub pq_secret: Option<Vec<u8>>,
    pub final_key: Vec<u8>,
    pub pq_active: bool,
}

Result of a hybrid key exchange (classical Noise XX + optional ML-KEM-768).

Fields

classical_secret: Vec<u8>

Classical shared secret (from Noise XX X25519 DH).

pq_secret: Option<Vec<u8>>

Post-quantum shared secret (from ML-KEM-768, if both sides support).

final_key: Vec<u8>

Final combined key: SHA-256(classical || pq || “weftos-hybrid-kem-v1”).

pq_active: bool

Whether PQ was used.

Implementations

impl HybridKeyExchange

pub fn combine(classical: Vec<u8>, pq: Option<Vec<u8>>) -> Self

Combine classical and PQ secrets into a final hybrid key.

The combination is: SHA-256(classical || pq || "weftos-hybrid-kem-v1"). When pq is None, the domain tag still differentiates the output from a raw classical key.

Trait Implementations

impl Clone for HybridKeyExchange

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HybridKeyExchange

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

Formats the value using the given formatter.
