Struct Ciphertext 

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

The ciphertext computed by the encapsulator.

Implementations

impl Ciphertext

pub fn as_array(&self) -> &[u8; 96]

Trait Implementations

impl AsRef<[u8]> for Ciphertext

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

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

impl Debug for Ciphertext

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

Formats the value using the given formatter.

impl<'sk> Decapsulator<Ciphertext> for SecretKey<'sk>

Available on crate feature kem only.

fn try_decap( &self, ciphertext: &Ciphertext, ) -> Result<SharedSecret<Ciphertext>, Error>

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

impl EncappedKey for Ciphertext

Available on crate feature kem only.

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

The size, in bytes, of an encapsulated key.

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

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

type SenderPublicKey = ()

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

type RecipientPublicKey = PublicKey<'static>

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<Ciphertext> for ClassicMcEliece

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

impl From<[u8; 96]> for Ciphertext

fn from(data: [u8; 96]) -> Self

Converts to this type from the input type.
