Class AesEncryptor

java.lang.Object
org.jivesoftware.util.AesEncryptor
All Implemented Interfaces:
Encryptor
public class AesEncryptor extends Object implements Encryptor
Utility class providing symmetric AES encryption/decryption. To strengthen the encrypted result, use the setKey(byte[]) method to provide a custom key prior to invoking the encrypt(java.lang.String) or decrypt(java.lang.String) methods.
