Class MldsaKeyGenBuilder

java.lang.Object

zeroecho.core.alg.mldsa.MldsaKeyGenBuilder

All Implemented Interfaces:

AsymmetricKeyPairGenerator<MldsaKeyGenSpec>

public final class MldsaKeyGenBuilder
extends Object
implements AsymmetricKeyPairGenerator<MldsaKeyGenSpec>

Key pair builder for ML-DSA (FIPS 204) using the Bouncy Castle provider.

This builder maps MldsaKeyGenSpec to the appropriate org.bouncycastle.jcajce.spec.MLDSAParameterSpec constant. Reflection is used to avoid a hard dependency on any particular set of parameter constants across provider versions.
