Method Detail

initialize

public void initialize(AlgorithmParameterSpec params,
                       SecureRandom random)
                throws 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 KeyPairGeneratorSpi

Parameters:

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

random - unused

Throws:

InvalidAlgorithmParameterException

initialize

public void initialize(int curveID,
                       SecureRandom random)

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

Specified by:

initialize in class KeyPairGeneratorSpi

Parameters:

curveID - Curve ID 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 KeyPair generateKeyPair()
                        throws LunaException

Generates a key pair.

Specified by:

generateKeyPair in class KeyPairGeneratorSpi

Throws:

LunaException - exception
