Usage

From source file:MainClass.java

public static void main(String[] args) throws Exception {
    String creditCard = "1234567890";

    KeyGenerator keyGenerator = KeyGenerator.getInstance("DESede");

    Key key = keyGenerator.generateKey();
    Cipher cipher = Cipher.getInstance("DESede");
    cipher.init(Cipher.ENCRYPT_MODE, key);

    SealedObject so = new SealedObject(creditCard, cipher);

    String unencryptedCreditCard = (String) so.getObject(key);

    System.out.println(unencryptedCreditCard);
