Well... technically the SMB protocol (as it exists today) is defined by the
Microsoft specifications, and they don't include any support for encryption.

There is, unfortunately, no "official" specification of the Unix extensions
for SMB (only an old draft that doesn't include encryption, IIRC).  Also, as
their name suggests, they're extensions to the protocol which means that
they're not part of the protocol itself.

Absolutely right to set the record straight.  I should have added the caveat
that the Unix extensions include support for encryption.

Don't forget to click your heels together and burn the tana leaves when the
moon is full over Vermont.  ;)
