java.lang.Object

net.jrodolfo.java_evolution.java24.quantum_resistant_crypto.ModuleLatticeDsaExample

public class ModuleLatticeDsaExample
extends Object

Demonstrates Java 24 module-lattice digital signature support.

ML-DSA is a post-quantum digital signature algorithm. A private key signs a message, and the matching public key verifies that the signature belongs to the original message. The example also verifies that a tampered message is rejected.

signAndVerify

public ModuleLatticeDsaResult signAndVerify(String message)
                                     throws NoSuchAlgorithmException,
InvalidKeyException,
SignatureException

Signs a message and verifies both the original and a tampered message.

Parameters:

message - the message to sign

Returns:

the signature bytes and verification outcomes

Throws:

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

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

SignatureException - if the signature operation fails
