How to digitally sign my .xll add-in

[Steven John Lally]

When I start up my add-in from visual studio I get a warning saying that Microsoft Office has identified a potential security concern.

I have some knowledge on what a digital certificate is but have no idea how to sign my add-in. 

I'd like to know how I can sign it so that users feel secure when our add-in is deployed to them.

Best Regards,

Steven

There are some related discussions on the Excel-DNA Google group too, if you search for "signtool":
