Trait kem::Encapsulator

pub trait Encapsulator<EK: EncappedKey> {
    fn try_encap<R: CryptoRng + RngCore>(
        &self, 
        csprng: &mut R, 
        recip_pubkey: &EK::RecipientPublicKey
    ) -> Result<(EK, GenericArray<u8, EK::NSecret>), Error>;
}

Represents the functionality of a key encapsulator. For unauthenticated encapsulation, Self can be an empty struct. For authenticated encapsulation, Self is a private key.

Required methods

fn try_encap<R: CryptoRng + RngCore>(
    &self,
    csprng: &mut R,
    recip_pubkey: &EK::RecipientPublicKey
) -> Result<(EK, GenericArray<u8, EK::NSecret>), Error>

Attempt 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.
