KyberPrivateKeySpec
public KyberPrivateKeySpec(byte[] keyToken, byte type) throws java.security.spec.InvalidKeySpecException
Creates an instance of this class from a key token and key type. The usage is defaulted to KeyHWAttributeValues.KEYMANAGEMENT.- Parameters:
keyToken
- The token associated with the private key. If this is a key label, then the label must conform to the character restrictions imposed by the platform you are executing on and should be in the ISO_8859_1 character encoding.type
- The type of the key Encrypted under the master key (KeyHWAttributeValues.MASTER) or outside the hardware in the PKDS (KeyHWAttributeValues.PKDS) or in the clear (KeyHWAttributeValues.CLEAR). Please note that it is recommended to use theKeyLabelKeySpec
class to create a key specification using aKeyHWAttributeValues.PKDS
type of key.- Throws:
java.security.spec.InvalidKeySpecException

keyToken
- The token associated with the private key. If this is a key label, then the label must conform to the character restrictions imposed by the platform you are executing on and should be in the ISO_8859_1 character encoding.type
- The type of the key Encrypted under the master key (KeyHWAttributeValues.MASTER) or outside the hardware in the PKDS (KeyHWAttributeValues.PKDS) or in the clear (KeyHWAttributeValues.CLEAR). Please note that it is recommended to use theKeyLabelKeySpec
class to create a key specification using aKeyHWAttributeValues.PKDS
type of key.usage
- Determines for what purpose the key pair is to be used. KeyHWAttributeValues.KEYMANAGEMENT is for signing purposes and must be used.
