A digital signature is often used to identify the author of a workbook that contains macros. It is a way of confirming that the macro code has not been tampered with and ensuring that the macro was created by the person who claims to have created it. Adding a digital signature is not the first step, and a digital ID is not needed before adding a digital signature. Digital certificates may be issued by Microsoft, but this is not always the case.
