Class MLDSAKeyPairGenerator

java.lang.Object

java.security.KeyPairGeneratorSpi

com.ibm.crypto.hdwrCCA.provider.MLDSAKeyPairGenerator

public class MLDSAKeyPairGenerator
extends KeyPairGeneratorSpi

This class generates ML-DSA public/private key pairs via hardware. An application can specify the size, the key label, the storage type and usage type of the key pair to be generated via an instance of the MLDSAKeyParameterSpec class.
