Trait Implementations

impl AsRef<[u8]> for Sm9EncappedKey

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for Sm9EncappedKey

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

Formats the value using the given formatter.

impl Decapsulator<Sm9EncappedKey> for UserPrivateKey

fn try_decap( &self, encapped_key: &Sm9EncappedKey ) -> Result<SharedSecret<Sm9EncappedKey>, Error>

Attempt to decapsulate the given encapsulated key. Returns the shared secret on success, or an error if something went wrong.

impl EncappedKey for Sm9EncappedKey

type SharedSecretSize = UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B1>, B0>, B0>, B0>, B0>, B0>, B0>, B0>

The size, in bytes, of the shared secret that this KEM produces.

type EncappedKeySize = UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>

The size, in bytes, of an encapsulated key.

type SenderPublicKey = MasterPublicKey

Represents the identity key of an encapsulator. This is used in authenticated decapsulation.

type RecipientPublicKey = GenericArray<u8, UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>, B0>>

The public key of a decapsulator. This is used in encapsulation.

fn from_bytes( bytes: &GenericArray<u8, Self::EncappedKeySize> ) -> Result<Self, Error>

Parses an encapsulated key from its byte representation.

fn as_bytes(&self) -> &GenericArray<u8, Self::EncappedKeySize>

Borrows a byte slice representing the serialized form of this encapsulated key.

impl Encapsulator<Sm9EncappedKey> for <Sm9EncappedKey as EncappedKey>::SenderPublicKey

fn try_encap<R: RngCore + CryptoRng>( &self, csprng: &mut R, recip_pubkey: &<Sm9EncappedKey as EncappedKey>::RecipientPublicKey ) -> Result<(Sm9EncappedKey, SharedSecret<Sm9EncappedKey>), Error>

Attempts to encapsulate a fresh shared secret with the given recipient. The resulting shared secret is bound to the identity encoded in Self (i.e., authenticated wrt Self). If Self is empty, then this is equivalent to unauthenticated encapsulation. Returns the shared secret and encapsulated key on success, or an error if something went wrong.
