Class NegTokenInit

  • Direct Known Subclasses:
    NegTokenInit2
    public class NegTokenInit
extends SpnegoToken
    This class can encode and decode the SPNEGO negTokenInit Token.

    The entire token is an ASN.1 DER encoded sequence of bytes in little endian byte encoding.

    The following is the full ASN.1 specification of the token: 

     GSSAPI          ::=  [APPLICATION 0] IMPLICIT SEQUENCE {
   mech                MechType,
   negTokenInit        NegotiationToken
 }

 NegotiationToken ::=  CHOICE {
   negTokenInit   [0]  NegTokenInit,
   negTokenTarg   [1]  NegTokenTarg
 }

 NegTokenInit     ::=  SEQUENCE {
   mechTypes      [0]  MechTypeList  OPTIONAL,
   reqFlags       [1]  ContextFlags  OPTIONAL,
   mechToken      [2]  OCTET STRING  OPTIONAL,
   mechListMIC    [3]  OCTET STRING  OPTIONAL
 }

 MechTypeList     ::=  SEQUENCE of MechType

 ContextFlags     ::=  BIT_STRING {
   delegFlag      (0),
   mutualFlag     (1),
   replayFlag     (2),
   sequenceFlag   (3),
   anonFlag       (4),
   confFlag       (5),
   integFlag      (6)
 }

 MechType         ::=  OBJECT IDENTIFIER

    In the context of this class only the NegTokenInit is covered.

    • When an InitToken is sent, it is prepended by the generic GSSAPI header.
    • The "mech" field of the GSSAPI header is always set to the SPNEGO OID (1.3.6.1.5.5.2)
    • The negTokenInit will have a lead byte of 0xa0 (the CHOICE tagged object).
