Class Headless_Authenticator

java.lang.Object

HiRISE.HiPlan.HiWeb.Headless_Authenticator

public class Headless_Authenticator
extends java.lang.Object

A mechanism for authenticating a HiWeb user. This class is purely headless; it does not generate a GUI interface, to allow for the possibility of using it without a graphic interface.

The user's HiWeb password is hashed before comparing with the password as stored in HiCat. Nevertheless, this class may not be 100% secure.
