Struct SecretKey 

pub struct SecretKey { /* private fields */ }

X-Wing hybrid KEM decapsulation (secret) key.

Combines an ML-KEM-768 and an X25519 secret key as specified in the X-Wing draft. The shared secret is derived via a combiner that hashes both component secrets together.

Example

use crypto::xwing::{generate_keypair, SecretKey, PublicKey};

let (secret_key, public_key) = generate_keypair();
let (shared_secret, ciphertext) = public_key.encapsulate();
let decapsulated = secret_key.decapsulate(&ciphertext).unwrap();
assert_eq!(shared_secret, decapsulated);

Implementations

impl SecretKey

pub fn to_bytes(&self) -> [u8; 32]

pub fn decapsulate(&self, ct: &[u8; 1120]) -> Result<[u8; 32], XWingError>

Trait Implementations

impl Clone for SecretKey

fn clone(&self) -> SecretKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SecretKey

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

Formats the value using the given formatter.

impl Eq for SecretKey

impl PartialEq for SecretKey

fn eq(&self, other: &SecretKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
