Class AESCryptor

java.lang.Object

maspack.crypt.CryptorBase

maspack.crypt.AESCryptor

All Implemented Interfaces:

Cryptor

public class AESCryptor
extends CryptorBase

A password encryption scheme that uses either a 128-bit,192-bit or 256-bit AES algorithm. To enable the 256-bit mode, you must install the JCE Unlimited Strength policy files: "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" <http://www.oracle.com/technetwork/java/javase/downloads/index.html>
