public class BinaryTokenCallback
extends java.lang.Object
implements javax.security.auth.callback.Callback
The BinaryTokenCallback
allows a credential token to be gathered
by the CallbackHandler
and pass it to the LoginModule
.
However, since the credential token is typically in byte format and difficult to input
interactively, it is usually passed to the LoginModule
programmatically.
