Hi Suhas,

No. JCIFS implements message signatures which are derived from the
session key negotiated during NTLM auth so there is some apparatus to
compute a key internally. But you cannot use JCIFS to sign and seal
streams of data. That would require crypto that is not required by
CIFS and so it's been left out.
