Class KyberKemSpi

java.lang.Object

iaik.security.kem.KeyEncapsulationMechanismSpi

iaik.security.pq.kyber.KyberKemSpi

public class KyberKemSpi
extends iaik.security.kem.KeyEncapsulationMechanismSpi

This class extends the KeyEncapsulationMechanismSpi and serves as an interface for users to encapsule and decapsule keys with the Kyber [0] Algorithm. Is being updated according to FIPS 203 Draft [1].
