java.security.KeyPairGeneratorSpi

com.ibm.crypto.hdwrCCA.provider.KyberKeyPairGenerator

public class KyberKeyPairGenerator
extends KeyPairGeneratorSpi

This class generates CRSTALS-Kyber 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 KyberKeyParameterSpec class.

Parameters:

params - the AlgorithmParameterSpec for this object.

random - the SecureRandom object for generating random numbers.

Throws:

InvalidAlgorithmParameterException - thrown when parameter set is not recognized.

generateKeyPair

public KeyPair generateKeyPair()

Generates a CRYSTALS-Kyber key pair via hardware.

Specified by:

generateKeyPair in class KeyPairGeneratorSpi

Returns:

a KeyPair contains a pair of generated CRYSTALS-Kyber keys

Throws:

IllegalArgumentException - in the key label formal is not valid
