If you side the macros with the SDK, the Signtool utility allows you to apply a time stamp to the digital signature.
The time stamping service (you need to purchase a hardware device or subscribe to a time stamping service on the Internet), will validate that the applied signature was valid - at the time of time stamping.
This allows code to be trusted even if the code signing certificate is revoked, becomes time invalid, etc.
Just search on code signing or check out chapter 25 in the PKI 2008 book I wrote from MS PRess

Thanks Brian How can I apply a timestamp when I sign a macro?. Can't I do anything else to avoid signing again macros???. If I apply a timestamp, is that timestamp for ever???. Can I apply a timestamp forever???

Thanks in advance

When you signed the macros, did you apply a timestamp to the signature.
I do not think so, so you are looking at having to re-sign the macros.
A renewed certificate will have a different thumbprint and serial number (even if you renew with the same key pair)

Hi everyone:

My question is the following. I've hundreds of macros signed with a certificate from my own Microsoft CA. The certificate is just valid till next January 14th. I would like to renew the certificate so I had not to sign all macros again. What do I have to do so I can renew the certificate without having to sign all macros again??

It's very important for me because it's a lot of work signing all macros again

Thanks in advance
