Expand description

Key encapsulation mechanism (KEM) port — ML-KEM-1024.

All operations are constant-time with respect to secret key material.

Required Methods§

Source

fn generate_keypair(&self) -> Result<KeyPair, CryptoError>

Generate a fresh key pair.

§Errors

Returns CryptoError::KeyGenFailed if the RNG or parameter validation fails.

Source

fn encapsulate(&self, public_key: &[u8]) -> Result<(Bytes, Bytes), CryptoError>

Encapsulate a shared secret using the recipient’s public key.

Returns (ciphertext, shared_secret).

§Errors

Returns CryptoError::EncapsulationFailed on invalid key material.

Source

fn decapsulate( &self, secret_key: &[u8], ciphertext: &[u8], ) -> Result<Bytes, CryptoError>

Decapsulate a shared secret using the holder’s secret key.

§Errors

Returns CryptoError::DecapsulationFailed on invalid key or ciphertext.
