I've played around with the SelfCert.exe program that comes with Window as a way to add some level of confidence to my VBA code (some of my users are afraid of macros due to virus problems and so won't use the tools I create since enabling macros is required and adds lots more functionality than I can write with plain Excel).

What other types of certification can I add to a VBA project? Are there international issues to consider (my audience is world-wide). I recently heard of an error regarding encryption from one of my international users but I don't have the exact wording of the message.

Any suggestions/hints would be greatly appreciated.
