Bill - The technology that we export as part of RPK InvisiMail, is 
world-class strong crypto.  Key size options are 607 bits and 1279.  The 
math behind the system is based on the same as that of D-H.  There is no 
snake oil.  There was no intentional or unintentional attempt to mislead 
any government authority.  We also did not request an export license, 
because there is no need to do so in New Zealand as long as the export is 
by means of the Internet.  Peter G. knows this as well.  The story may be 
different for physical export on disk, disc or tape, although we cannot 
concur with Peter's personal experience.  Our experience is that we get 
pretty good treatment from the NZ authorities.  We also may use a different 
approach.  I have often heard that you can often get a better response when 
using honey than vinegar.  Therein may explain differences in our 
respective experiences.  I have personally met with the Minister of Trade 
for New Zealand.  His views and those of his staff seemed to be acceptable 
to us and have not imposed any undue restrictions of our business or our 
ability to operate.

I was amused to receive two mail messages back-to-back,
one from Peter Gutmann talking about New Zealand having one of the
strictest formal export controls in the world, and one from
RPK New Zealand talking about how their encryption product is
not export-controlled because it's from NZ, not the US,
and how their RPK Fast Public Key Encryptonite(tm) Engine
is the strongest crypto in the world.  Either they haven't
bothered asking for export permission, or they asked in such a way
that the export bureaucrats didn't notice it was crypto and
regulated by their crypto export preventers, or their crypto
somehow falls through the cracks, e.g. by using an algorithm with
public keys shorter than 512 bits (works for ECC, not RSA)
and private keys shorter than 40 bits (or 41 on a good day),
or perhaps passes the "snake oil test" for export permission.
I suppose it's possible that the NZ Export Bureaucrats have
lightened up since Peter's last dealings with them,
but it's not likely.

========= From Peter Gutmann's web page
This policy has resulted in New
Zealand enjoying the dubious distinction of having the strictest export
controls on earth, with everything ranging from crypto hardware down to
software, library books, computer magazines, and journals being restricted
from export.  It's not even possible for a university to publish academic
research without prior permission from a government agency, and the
requirements for obtaining this permission are structured to ensure that 
they
can never be fulfilled.  You can find the information on:
