Re-exports

pub use digest::generic_array;

AeadCtxR	The HPKE receiver's context. This is what you use to `open` ciphertexts.
AeadCtxS	The HPKE senders's context. This is what you use to `seal` plaintexts.
EncappedKey	This holds the content of an encapsulated secret. It is output by the `encap` and `encap_auth` functions.
Psk	A preshared key, i.e., a secret that the sender and recipient both know before any exchange has happened
PskBundle	Contains preshared key bytes and an identifier

HpkeError	Describes things that can go wrong when trying to seal or open a ciphertext
OpModeR	The operation mode of the receiver's side of HPKE. This determines what information is folded into the encryption context derived in the `setup_receiver` functions. You can include a preshared key, the identity key of the sender, both, or neither.
OpModeS	The operation mode of the sender's side of HPKE. This determines what information is folded into the encryption context derived in the `setup_sender` functions. You can include a preshared key, the identity key of the sender, both, or neither.

Kem	Defines a combination of key exchange mechanism and a KDF, which together form a KEM
KeyExchange	This trait captures the requirements of a key exchange mechanism. It must have a way to generate keypairs, perform the KEX computation, and marshal/umarshal KEX pubkeys
Marshallable	Implemented by types that have a fixed-length byte representation
Unmarshallable	Implemented by types that can be deserialized from byte representation

setup_receiver	Initiates an encryption context given a private key `sk` and an encapsulated key which was encapsulated to `sk`'s corresponding public key
setup_sender	Initiates an encryption context to the given recipient. Does an "authenticated" encapsulation if `sk_sender_id` is set. This ties the sender identity to the shared secret.
single_shot_open	Does a `setup_receiver` and `AeadCtx::open` in one shot. That is, it does a key decapsulation for the specified recipient and decrypts the provided plaintext in place. See `setup::setup_reciever` and `AeadCtx::open` for more detail.
single_shot_seal	Does a `setup_sender` and `AeadCtx::seal` in one shot. That is, it does a key encapsulation to the specified recipient and encrypts the provided plaintext in place. See `setup::setup_sender` and `AeadCtx::seal` for more detail.
