public class HybridKEMPrivateKeyParameters
extends AsymmetricKeyParameter

Private (decapsulation) key of one of the ML-KEM / NIST curve hybrid KEMs of draft-irtf-cfrg-concrete-hybrid-kems used with HPKE (HPKE.kem_MLKEM768_P256, HPKE.kem_MLKEM1024_P384). The key is a 32-byte seed, which is also its serialized form; the ML-KEM and curve components are expanded from it.

Method Summary

Modifier and Type	Method and Description
byte[]	getEncoded()
short	getKemId()
HybridKEMPublicKeyParameters	getPublicKeyParameters()
byte[]	getSeed() Return the 32-byte seed the key pair is derived from, which is the key's serialized form.
