 * Like SimpleEncryption except it uses a stored secret key.  If the key file is missing, it makes up a new one.
 *
 * WARNING: NOT RECOMMENDED. If you lose the secret key file your encrypted passwords will be unavailable.  Instead, secure
 * your operationg environment and use something like ldap or a database to store passwords in.
 *
 * To use, include something like this in the rmi-naming module of var/config/config.xml:
 *
 * 
 * var/security/ConfiguredSecretKey.ser
