Class DigestHashCallback

java.lang.Object

org.jboss.sasl.callback.DigestHashCallback

All Implemented Interfaces:

Callback

public class DigestHashCallback
extends Object
implements Callback

Callback to allow Digest mechanisms to request the pre-digested {username : realm : password} value instead of the plain text password.

The benefit of this callback is that the server no longer needs to store the raw plain text password of the user.

This Callback has accessor methods for both the raw byte[] of the hash and the hex encoded String of the hash, however only one format of the hash should actually be set - the Callback will convert to the other format should the get method be called.
