Method Detail

initialize

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

Initializes the key pair generator with the given parameter spec. The parameter spec must describe a supported named curve.

The Luna HSM supplies its own source of randomness so the random parameter is ignored.

Overrides:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

params - the parameter set used to generate the keys. Must be an object of class ECParameterSpec

random - unused

Throws:

java.security.InvalidAlgorithmParameterException

initialize

public void initialize(int keyLength,
              java.security.SecureRandom random)

Initialize the key pair generator with the given key length. If possible initialize(AlgorithmParameterSpec, SecureRandom) should be used instead.

Specified by:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

keyLength - key length to use in key generation

random - Ignored -- the HSM uses its own RNG

initialize

public void initialize(int curveID)

Initialize the key pair generator with the given curve id. If possible initialize(AlgorithmParameterSpec, SecureRandom) should be used instead.

Parameters:

curveID - Curve ID to use in key generation

generateKeyPair

public java.security.KeyPair generateKeyPair()
                                      throws LunaException

Generates a key pair.

Specified by:

generateKeyPair in class java.security.KeyPairGeneratorSpi

Throws:

LunaException - exception
