Package org.bouncycastle.crypto.hpke

Class Summary

AEAD	AEAD wrapper backing HPKEContext.seal(byte[], byte[])/HPKEContext.open(byte[], byte[]).
HPKE	Hybrid Public Key Encryption (HPKE) per RFC 9180.
HPKEContext	An HPKE encryption / decryption context produced by one of the (recipient) factory methods, or — via the HPKEContextWithEncapsulation subclass — by one of the (sender) factories.
HPKEContextWithEncapsulation	Sender-side HPKEContext that additionally carries the octet string produced by the KEM's encapsulation step.
HybridKEMPrivateKeyParameters	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).
HybridKEMPublicKeyParameters	Public (encapsulation) 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 ML-KEM encapsulation key followed by the uncompressed curve point, which is also its serialized form.
KEM	Abstract base for HPKE Key Encapsulation Mechanisms per RFC 9180 §4.
