org.apache.directory.shared.kerberos.messages.KerberosMessage

org.apache.directory.shared.kerberos.messages.EncApRepPart

All Implemented Interfaces:

org.apache.directory.api.asn1.Asn1Object

public class EncApRepPart
extends KerberosMessage

Encrypted part of the application response. It will store the object described by the ASN.1 grammar :

 EncAPRepPart    ::= [APPLICATION 27] SEQUENCE {
         ctime           [0] KerberosTime,
         cusec           [1] Microseconds,
         subkey          [2]  OPTIONAL,
         seq-number      [3] UInt32 OPTIONAL
 }
