Class DilithiumKeyPairGenerator

  • public class DilithiumKeyPairGenerator
extends java.security.KeyPairGeneratorSpi
    This class generates CRSTALS-Dilithium 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 DilithiumKeyParameterSpec class.
