public abstract void initialize(int keysize, SecureRandom random)
keysize
- the keysize. This is an
algorithm-specific metric, such as modulus length, specified in
number of bits.random
- the source of randomness for this generator.
InvalidParameterException
- if the keysize
is not
supported by this KeyPairGeneratorSpi object.public void initialize(AlgorithmParameterSpec params, SecureRandom random) throws InvalidAlgorithmParameterException
This concrete method has been added to this previously-defined abstract class. (For backwards compatibility, it cannot be abstract.) It may be overridden by a provider to initialize the key pair generator. Such an override is expected to throw an InvalidAlgorithmParameterException if a parameter is inappropriate for this key pair generator. If this method is not overridden, it always throws an UnsupportedOperationException.
params
- the parameter set used to generate the keys.random
- the source of randomness for this generator.
InvalidAlgorithmParameterException
- if the given parameters
are inappropriate for this key pair generator.public abstract KeyPair generateKeyPair()
