Digital certificates
I need to digitally sign a couple of macros. Who is the best/cheapest source
of a digital certificate? What are the pitfalls that I might not be aware of I've never done it before. I know nothing about it Thanks M |

Digital certificates
You can have Best or you can have Cheapest, but you can't have both at the
same time. Cheapest is a self-signed digital certificate that you can create your own digital certificate. Rather than repeat the Help instructions here, I'll simply say that to find out how, open Excel and use its Help to search for the phrase create digital signature look for the returned topic "Create your own digital certificate'. It tells how and the 'pitfalls'. Also, go into the VB Editor and search for help on digital signature and it will return a list of properties with example code that you can use in the project to determine if a certificate is attached to it, who signed it, etc. that you can use to verify that your signature is still attached to the project and prevent code from running if someone has modified it (which will result in the certificate removal). Best is certificate with the public key stored in a trusted Root Certificate server by someone like VeriSign and others. I think that the least expensive of these that I've seen was offered by GoDaddy.com recently. You definitely want to shop around some, as some sellers want major $$ for a certificate through them. Once you have a digital certificate, you attach it to a project from within the VB Editor, choosing Tools | Digital Signature from the VB Editor menu toolbar.
