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();
