public abstract class KEM

extends java.lang.Object

Abstract base for HPKE Key Encapsulation Mechanisms per RFC 9180 §4.

Concrete subclass DHKEM implements the five DHKEM variants registered by RFC 9180 (P-256/P-384/P-521/X25519/X448). External implementations — e.g. post-quantum KEMs such as ML-KEM or the hybrid X25519+Kyber768 used by MLS — can be plugged in by subclassing this class and passing the instance to the constructor; the framework only requires: / — the basic KEM encapsulate / decapsulate pair returning . — a sender-supplied-ephemeral variant used by the OHTTP test vectors and any deterministic KAT. / — the authenticated variant used by / . / — fresh and deterministic key generation respectively. / / / — the KEM-specific wire encoding. — the byte-length of the output, used by the facade to allocate space.
