CLASSES

  class GSS(baseobj.BaseObj)
GSS Data object
This is a base object and should not be instantiated.
It gives the following methods:
    # Decode data preceding the RPC payload when flavor is RPCSEC_GSS
    x.decode_gss_data()
    # Decode data following the RPC payload when flavor is RPCSEC_GSS
    x.decode_gss_checksum()

Methods defined here:
---------------------

decode_gss_checksum(self)
Decode GSS checksum

decode_gss_data(self)
Decode GSS data
