pub struct DhP384HkdfSha384;

Represents DHKEM(P-384, HKDF-SHA384)

Trait Implementations

impl Kem for DhP384HkdfSha384

fn derive_keypair(ikm: &[u8]) -> (Self::PrivateKey, Self::PublicKey)

Deterministically derives a keypair from the given input keying material

Requirements

This keying material SHOULD have as many bits of entropy as the bit length of a secret key, i.e., 8 * Self::PrivateKey::size(). For X25519 and P-256, this is 256 bits of entropy.

fn sk_to_pk( sk: &<DhP384 as DhKeyExchange>::PrivateKey ) -> <DhP384 as DhKeyExchange>::PublicKey

Computes the public key of a given private key

type PublicKey = <DhP384 as DhKeyExchange>::PublicKey

The key exchange’s public key type. If you want to generate a keypair, see Kem::gen_keypair or Kem::derive_keypair

type PrivateKey = <DhP384 as DhKeyExchange>::PrivateKey

The key exchange’s private key type. If you want to generate a keypair, see Kem::gen_keypair or Kem::derive_keypair

type EncappedKey = EncappedKey

The encapsulated key for this KEM. This is used by the recipient to derive the shared secret.

const KEM_ID: u16 = 17u16

The algorithm identifier for a KEM implementation

fn gen_keypair<R: CryptoRng + RngCore>( csprng: &mut R ) -> (Self::PrivateKey, Self::PublicKey)

Generates a random keypair using the given RNG
