public abstract class LunaKeyGeneratorSecret
extends javax.crypto.KeyGeneratorSpi

Base class for all key generator engine classes. The keys generated by this class can only be extracted from the HSM if setSecretKeysExtractable(true) was called on LunaSlotManager prior to calling generateKey in this class.

Modifier and Type	Method and Description
javax.crypto.SecretKey	engineGenerateKey()
void	engineInit(java.security.spec.AlgorithmParameterSpec spec, java.security.SecureRandom random) The Luna provider does not support key generation with a supplied parameter spec.
void	engineInit(int keySize, java.security.SecureRandom random) Initializes this key generator for a certain keysize.
void	engineInit(java.security.SecureRandom random) The Luna provider provides its own source of randomness on the HSM, so this method does nothing.

                      int keySize)

Method Detail

engineInit

public void engineInit(int keySize,
              java.security.SecureRandom random)
                throws java.security.InvalidParameterException

Initializes this key generator for a certain keysize. The Luna provider provides its own source of randomness on the HSM, so the random parameter is ignored.

Specified by:

engineInit in class javax.crypto.KeyGeneratorSpi

Parameters:

keySize - the keysize. This is an algorithm-specific metric, specified in number of bits. The key size must be a multiple of 8 (i.e. byte-aligned)

random - unused

Throws:

java.security.InvalidParameterException - if the keysize is invalid

engineInit

public void engineInit(java.security.SecureRandom random)
                throws java.security.ProviderException

The Luna provider provides its own source of randomness on the HSM, so this method does nothing.

Specified by:

engineInit in class javax.crypto.KeyGeneratorSpi

Throws:

java.security.ProviderException

engineInit

public void engineInit(java.security.spec.AlgorithmParameterSpec spec,
              java.security.SecureRandom random)
                throws java.security.InvalidAlgorithmParameterException

The Luna provider does not support key generation with a supplied parameter spec. Use engineInit(int, SecureRandom) instead.

Specified by:

engineInit in class javax.crypto.KeyGeneratorSpi

Throws:

java.lang.UnsupportedOperationException - exception

java.security.InvalidAlgorithmParameterException

engineGenerateKey

public javax.crypto.SecretKey engineGenerateKey()

Specified by:

engineGenerateKey in class javax.crypto.KeyGeneratorSpi
