Class ModuleLatticeKemExample

java.lang.Object

net.jrodolfo.java_evolution.java24.quantum_resistant_crypto.ModuleLatticeKemExample

public class ModuleLatticeKemExample
extends Object

Demonstrates Java 24 module-lattice key encapsulation support.

ML-KEM is a post-quantum key encapsulation mechanism. Like the Java 21 KEM example, the sender uses the receiver's public key to create a shared secret and an encapsulation message. The receiver uses the private key and the encapsulation message to recover the same shared secret.

exchange

public ModuleLatticeKemResult exchange()
                                throws NoSuchAlgorithmException,
InvalidKeyException,
DecapsulateException

Runs a complete in-memory ML-KEM exchange.

Returns:

sender secret, receiver secret, and encapsulation bytes

Throws:

NoSuchAlgorithmException - if ML-KEM is not available from the active providers

InvalidKeyException - if generated keys cannot be used by the KEM provider

DecapsulateException - if the encapsulation cannot be decoded by the receiver
