If you sign macros without a time stamp, the signature remains valid during the validity period of your certificate.į) Note that Digitally signing your macro project is different from trusted locations. When you digitally sign macros, it is important to obtain a time stamp so that other users can verify your signature if the certificate used for the signature has expired, or has been revoked after signing.

Corporate administrators can re-sign templates and add-ins so that they can control what users run on their computers.Į) If you create an add-in that adds code to a macro project, your code should determine if the project is digitally signed and should notify the users of the consequences of changing a signed project before they continue. Therefore, locking your macro project doesn't prevent another user from replacing the digital signature with another signature. Your digital signature does not prove that you wrote the project. Your digital signature implies that you guarantee the project has not been tampered with since you signed it.
However, if you have the valid digital certificate that was previously used to sign the project on your computer, the macro project is automatically re-signed when you save it.ĭ) If you want to prevent users of your solution from accidentally changing your macro project and invalidating your signature, lock the macro project before you sign it. Select a certificate and click OK.Ĭ) It is recommended that you sign macros only after your solution has been tested and ready for distribution: when code in a signed macro project is changed in any way, its digital signature is removed. In the Customize the Ribbon list, click Developer, and then click OK.ī) If you haven't selected a digital certificate or want to use another, click Choose.

On the Developer tab, in the Code group, click Visual Basic. Install and Open the software and select the corrupt Excel File. In the trust center, 'Trust access to the VBA project model' is NOT checked. Which I believe is correct for what I want. In the trust center, in Macro Settings, it's set to 'Disable all Macros with Notification'. VBA editor is NOT open when I open the file. Open the file that contains the macro project that you want to sign. I want Excel to prompt me to enable Macros like it did before. Here is how you can digitally sign your macro project: Without digitally signing, there is no way, you can have it run on any workstation without any warning since that defeats the whole purpose of security built around macros. Even though the file moves around, you can use a digital certificate to sign your macro project using a certificate from a trusted CA.Īctually the purpose of the function in MS Office to digitally sign macros projects is so that it runs from any location which has trusted macros enabled and run it without a warning.
