Crypto Util

This library provides a set of classes that make using Java's crypto library easy. This library was written because the author got fed up with writing variations of the same code whenever he needed to deal with encryption.

Note: this library is developed against Java 1.8.

Example

Let's assume you need to encrypt the string "foobar" according to AES using the mode "AES/CBC/PKCS5Padding". Then the following will get you sorted:

// You should save this key in a secure location.
// You will need it for decryption.
Key key = KeyToolFactory.getInstance().aes128key().get();
AesCryptoTool tool = new AesCryptoTool(key);
Optional<EncryptedData> encryptedOptional =
  tool.encrypt("foobar".getBytes());

encryptedOptional.ifPresent(
  (encryptedData) -> {
    String json = encryptedData.toString();
    System.out.println(json);
  }
);
