Class RegistrationKeyManager

java.lang.Object
  jfig.utils.RegistrationKeyManager

public final class RegistrationKeyManager

extends java.lang.Object

manage and check registration keys for jfig. A single key currently consists of six groups of four hex digits each, separated by hyphens, e.g. "9a13-babe-cafe-0042-1f83-9876". The algorithm used is very simple; cracking it will offer no real satisfaction to hackers, but it will (hopefully) take more of your time than paying the registration fee...
