Example

The following example demonstrates how to generate a DSS keypair.

 IKeyPairGenerator kpg = KeyPairGeneratorFactory.getInstance(Registry.DSS_KPG);
 HashMap map = new HashMap();
 map.put(DSSKeyPairGenerator.MODULUS_LENGTH, new Integer(512));
 map.put(DSSKeyPairGenerator.USE_DEFAULTS, new Boolean(false));
 kpg.setup(map);
 KeyPair kp = kpg.generate();
 
 BigInteger p1 = ((DSAPublicKey) kp.getPublic()).getParams().getP();
 BigInteger p2 = ((DSAPrivateKey) kp.getPrivate()).getParams().getP();
 
 BigInteger q1 = ((DSAPublicKey) kp.getPublic()).getParams().getQ();
 BigInteger q2 = ((DSAPrivateKey) kp.getPrivate()).getParams().getQ();
 
 BigInteger g1 = ((DSAPublicKey) kp.getPublic()).getParams().getG();
 BigInteger g2 = ((DSAPrivateKey) kp.getPrivate()).getParams().getG();
