java.security.KeyPairGeneratorSpi
com.ibm.crypto.hdwrCCA.provider.KyberKeyPairGenerator
@Deprecated(since="21.0.11.0", forRemoval=true) public class KyberKeyPairGenerator extends KeyPairGeneratorSpi
Deprecated, for removal: This API element is subject to removal in a future version.
Replaced by ML-KEM implementation. This CRYSTALS-Kyber implementation is deprecated and will be removed in a future release, in alignment with NIST's latest recommendations for post-quantum cryptography modernization. Users should transition to the finalized ML-KEM standards.
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.
