Method Detail

getTickets

public Ticket[] getTickets()

Returns all the Tickets in this message

getTicketInfo

public Credential[] getTicketInfo()
                           throws NotYetDecryptedException

Returns all the Credentials in this message

getNonce

public int getNonce()
             throws NotYetDecryptedException

Returns the nonce in this message, or -1 if absent

getTimeStamp

public Date getTimeStamp()
                  throws NotYetDecryptedException

Returns the timestamp in this message. The returned time is a combination of the timestamp and usec fields in the ASN.1 definition of EncKrbCredPart, correct to the resolution of a Java Date (ie. fractional milliseconds are ignored).

getSenderAddress

public InetAddress getSenderAddress()
                             throws NotYetDecryptedException

Returns the sender address in this message, or null if absent

getReceiverAddress

public InetAddress getReceiverAddress()
                               throws NotYetDecryptedException

Returns the receiver address in this message, or null if absent
