Usage

From source file:MainClass.java

public static void main(String[] args) throws Exception {
    String alg = "DSA";
    KeyPairGenerator kg = KeyPairGenerator.getInstance(alg);
    KeyPair keyPair = kg.genKeyPair();

    Vector v = new Vector();
    v.add("This is a test!");
    Signature sign = Signature.getInstance(alg);
    SignedObject so = new SignedObject(v, keyPair.getPrivate(), sign);
    System.out.println(so.verify(keyPair.getPublic(), sign));
}

    KeyPairGenerator keyGen = KeyPairGenerator.getInstance("DSA");
    keyGen.initialize(1024);/*  w w w.j ava  2 s . c  o m*/
    KeyPair keypair = keyGen.genKeyPair();
    PrivateKey privateKey = keypair.getPrivate();
    PublicKey publicKey = keypair.getPublic();

    Serializable o = new MyClass();
    Signature sig = Signature.getInstance(privateKey.getAlgorithm());
    SignedObject so = new SignedObject(o, privateKey, sig);

    sig = Signature.getInstance(publicKey.getAlgorithm());
    boolean b = so.verify(publicKey, sig);
    o = (MyClass) so.getObject();
