Document

Verifies that the signature in this SignedObject is the valid signature for the object stored inside, with the given verification key, using the designated verification engine.

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));
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    KeyPairGenerator keyGen = KeyPairGenerator.getInstance("DSA");
    keyGen.initialize(1024);//w  w  w  . j a v a 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();
