/**
 * This interface provides a way to respond to authentication challenge and
 * authentication response headers. When a client or server receives an
 * authentication challenge or authentication response header, the
 * <code>onAuthenticationChallenge()</code> or
 * <code>onAuthenticationResponse()</code> will be called, respectively, by the
 * implementation.
 * <P>
 * For more information on how the authentication procedure works in OBEX,
 * please review the IrOBEX specification at <A
 * HREF="http://www.irda.org">http://www.irda.org</A>.
 * <P>
 * <STRONG>Authentication Challenges</STRONG>
 * <P>
 * When a client or server receives an authentication challenge header, the
 * <code>onAuthenticationChallenge()</code> method will be invoked by the OBEX
 * API implementation. The application will then return the user name (if
 * needed) and password via a <code>PasswordAuthentication</code> object. The
 * password in this object is not sent in the authentication response. Instead,
 * the 16-byte challenge received in the authentication challenge is combined
 * with the password returned from the <code>onAuthenticationChallenge()</code>
 * method and passed through the MD5 hash algorithm. The resulting value is sent
 * in the authentication response along with the user name if it was provided.
 * <P>
 * <STRONG>Authentication Responses</STRONG>
 * <P>
 * When a client or server receives an authentication response header, the
 * <code>onAuthenticationResponse()</code> method is invoked by the API
 * implementation with the user name received in the authentication response
 * header. (The user name will be <code>null</code> if no user name was provided
 * in the authentication response header.) The application must determine the
 * correct password. This value should be returned from the
 * <code>onAuthenticationResponse()</code> method. If the authentication request
 * should fail without the implementation checking the password,
 * <code>null</code> should be returned by the application. (This is needed for
 * reasons like not recognizing the user name, etc.) If the returned value is
 * not <code>null</code>, the OBEX API implementation will combine the password
 * returned from the <code>onAuthenticationResponse()</code> method and
 * challenge sent via the authentication challenge, apply the MD5 hash
 * algorithm, and compare the result to the response hash received in the
 * authentication response header. If the values are not equal, an
 * <code>IOException</code> will be thrown if the client requested
 * authentication. If the server requested authentication, the
 * <code>onAuthenticationFailure()</code> method will be called on the
 * <code>ServerRequestHandler</code> that failed authentication. The connection
 * is <B>not</B> closed if authentication failed.
