Class PasswordFactory

java.lang.Object

org.apache.fulcrum.jce.crypto.PasswordFactory

All Implemented Interfaces:

PasswordParameters

public class PasswordFactory
extends java.lang.Object
implements PasswordParameters

The implementation supplies a default password in the case that the programmer don't want to have additional hassles. It is easy to reengineer the password being used but much better than a hard-coded password in the application. The code uses parts from Markus Hahn's Blowfish library found at http://blowfishj.sourceforge.net/
