Class KyberKeyGenSpec

java.lang.Object

zeroecho.core.alg.kyber.KyberKeyGenSpec

All Implemented Interfaces:

Describable, AlgorithmKeySpec

public final class KyberKeyGenSpec
extends Object
implements AlgorithmKeySpec, Describable

Key generation specification for the Kyber (ML-KEM) algorithm family.

KyberKeyGenSpec captures the choice of Kyber parameter set when generating a key pair. Kyber is a post-quantum key encapsulation mechanism (KEM) standardized as ML-KEM. The three supported security levels are represented by KyberKeyGenSpec.Variant values:

• KyberKeyGenSpec.Variant.KYBER512 - lowest cost, NIST level 1 security,
• KyberKeyGenSpec.Variant.KYBER768 - balanced choice, NIST level 3 security,
• KyberKeyGenSpec.Variant.KYBER1024 - strongest, NIST level 5 security.

Usage

Instances of this class are passed to the Kyber key builder to select the desired parameter set:

CryptoAlgorithm kyber = new KyberAlgorithm();
KeyPair kp = kyber.asymmetricKeyPairGenerator(KyberKeyGenSpec.class)
                  .generateKeyPair(KyberKeyGenSpec.kyber768());

The spec is immutable and may be safely shared between threads.
