Class DesEncrypter

java.lang.Object
  com.microdeveloper.security.encryption.DesEncrypter

public class DesEncrypter
extends Object

A Triple DES with MD5 encryption utility that encrypts and decrypts the given text. This variant uses a pass phrase to perform the encryption. Because the encryption is 156-bit strong, the class is not suitable for export. Additionally, because the passphrase is in the form of text, care should be taken not to expose the passkey during usage.
