Perhaps, but perhaps not.

Send over a minimum project skeleton which exhibits the behavior. I
will get it working for you this weekend. It is time to try out my
past speculations.

What Development Environment? My test lab (at the house) has the
following available:

VC++ 6.0 Enterprise
Visual Studio 7.0 (no 7.1)
Visual Studio 8.0

Keep in mind I am a System Administrator and Security Engineer. I
program for fun (and the challenge). Money is not in the picture yet
:)

With that said, I should be able to make headway on it. And I have
others who are programming resources I can call on when I hit a brick
wall.

It is something that needs to be added to 'Compiling and Integrating
Crypto++ into the Microsoft Visual C++ Environment'
(http://www.codeproject.com/tips/CryptoPPIntegration.asp). I just
haven't had the time to set up test cases to find the work around.
