Class StringEncrypter

java.lang.Object

org.primefaces.util.StringEncrypter

public class StringEncrypter
extends Object

----------------------------------------------------------------------------- The following example implements a class for encrypting and decrypting strings using several Cipher algorithms. The class is created with a key and can be used repeatedly to encrypt and decrypt strings using that key. Some of the more popular algorithms are: Blowfish DES DESede PBEWithMD5AndDES PBEWithMD5AndTripleDES TripleDES
