Returns the algorithm that was used to seal this object.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {

    SecretKey key = KeyGenerator.getInstance("DES").generateKey();

    Cipher ecipher = Cipher.getInstance("DES");
    ecipher.init(Cipher.ENCRYPT_MODE, key);

    SealedObject so = new SealedObject(new MySecretClass(), ecipher);

    String algoName = so.getAlgorithm(); // DES

    Cipher dcipher = Cipher.getInstance("DES");
    dcipher.init(Cipher.DECRYPT_MODE, key);
    MySecretClass o = (MySecretClass) so.getObject(dcipher);

}
