Struct PrivateKey768 

pub struct PrivateKey768(/* private fields */);

An ML-KEM-768 private key.

Implementations

impl PrivateKey768

pub fn generate() -> (Vec<u8>, PrivateKey768, [u8; 64])

Generates a random public/private key pair returning a serialized public key, a private key, and a private seed value that can be used to regenerate the same private key in the future.

pub fn from_seed(seed: &[u8; 64]) -> Self

Regenerate a private key from a seed value.

pub fn to_public_key(&self) -> PublicKey768

Derives the public key corresponding to this private key.

pub fn decapsulate(&self, ciphertext: &[u8]) -> Option<[u8; 32]>

Decapsulates a shared secret from a ciphertext. This function only returns None if ciphertext is the wrong length. For invalid ciphertexts it returns a key that will always be the same for the same ciphertext and private key, but which appears to be random unless one has access to the private key. These alternatives occur in constant time. Any subsequent symmetric encryption using the result must use an authenticated encryption scheme in order to discover the decapsulation failure.
