OK - and crypto++ - do you have all its assembler already?
Presumably you could defer to the built-in crypto on Windows?

Ha - I'd been hoping you'd do that while I struggled to figure out sspi
on Windows. I had a
backup plan to use coroutines and bsd polarssl too. I'm a noob at the
security stuff tho and
have yet to do more than point waf at botan anyway - so I don't feel
confident. I could be
efficient at it.
