better than prev reply!

A better reply after searching elsewhere on the board:

there's a site www.updatexp.com - they have a whole section
dedicated to cryptographic services problems, including a
complete step-by-step run-through which worked first time
for me.

To get straight to the article, use
www.updatexp.com/cryptographic-service.html

Enjoy!
