Class KeyPairGeneratorSpi
KeyPairGeneratorSpi is the interface used to generate key pairs
for security algorithms.
protected Object | clone()- We override clone here to make it accessible for use by
DummyKeyPairGenerator.
|
abstract KeyPair | generateKeyPair()- Generates a KeyPair according the rules for the algorithm.
|
abstract void | initialize(int keysize, SecureRandom random)- Initialize the KeyPairGeneratorSpi with the specified
key size and source of randomness
|
void | initialize(AlgorithmParameterSpec params, SecureRandom random)- Initialize the KeyPairGeneratorSpi with the specified
AlgorithmParameterSpec and source of randomness
This is a concrete method.

generateKeyPair
public abstract KeyPair generateKeyPair()
Generates a KeyPair according the rules for the algorithm.
Unless intialized, algorithm defaults will be used. It
creates a unique key pair each time.
initialize
public abstract void initialize(int keysize,
SecureRandom random)Initialize the KeyPairGeneratorSpi with the specified
key size and source of randomness
keysize - size of the key to generaterandom - A SecureRandom source of randomness
initialize
public void initialize(AlgorithmParameterSpec params,
SecureRandom random)
throws InvalidAlgorithmParameterExceptionInitialize the KeyPairGeneratorSpi with the specified
AlgorithmParameterSpec and source of randomness
This is a concrete method. It may be overridden by the provider
and if the AlgorithmParameterSpec class is invalid
throw InvalidAlgorithmParameterException. By default this
method just throws UnsupportedOperationException.
params - A AlgorithmParameterSpec to intialize withrandom - A SecureRandom source of randomness
