Class DSSKeyPairGeneratorSpi

Implemented Interfaces:
DSAKeyPairGenerator

public class DSSKeyPairGeneratorSpi
extends KeyPairGeneratorAdapter
implements DSAKeyPairGenerator

The implementation of a KeyPairGenerator adapter class to wrap GNU DSS keypair generator instances.

In case the client does not explicitly initialize the KeyPairGenerator (via a call to an initialize() method), the GNU provider uses a default modulus size (keysize) of 1024 bits.

Method Details

initialize

public void initialize(int modlen,
                       boolean genParams,
                       SecureRandom random)
            throws InvalidParameterException
Specified by:
initialize in interface DSAKeyPairGenerator

initialize

public void initialize(int keysize,
                       SecureRandom random)
Initialize the KeyPairGeneratorSpi with the specified key size and source of randomness
Overrides:
initialize in interface KeyPairGeneratorAdapter
Parameters:
keysize - size of the key to generate
random - A SecureRandom source of randomness

initialize

public void initialize(DSAParams params,
                       SecureRandom random)
            throws InvalidParameterException
Specified by:
initialize in interface DSAKeyPairGenerator

initialize

public void initialize(AlgorithmParameterSpec params,
                       SecureRandom random)
            throws InvalidAlgorithmParameterException
Initialize 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.
Overrides:
initialize in interface KeyPairGeneratorAdapter
Parameters:
params - A AlgorithmParameterSpec to intialize with
random - A SecureRandom source of randomness
