## 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.
