Class XWingKEMGenerator

java.lang.Object
  org.bouncycastle.pqc.crypto.xwing.XWingKEMGenerator

All Implemented Interfaces:

EncapsulatedSecretGenerator

public class XWingKEMGenerator

extends java.lang.Object

implements EncapsulatedSecretGenerator

Implements the encapsulation process of the X-Wing hybrid Key Encapsulation Mechanism (KEM).

X-Wing is a general-purpose hybrid post-quantum/traditional KEM that combines X25519 and ML-KEM-768, as specified in the IETF draft: draft-connolly-cfrg-xwing-kem-07.

This class facilitates the generation of ciphertexts and shared secrets using a recipient's public key.
