Register a digital ID
Register your digital ID in Acrobat before you can use it. If you have a digital ID file that doesn't appear in your list of
digital IDs, you can search for the missing digital ID file. Then, add it to the list. You can identify digital ID files by
their filename extensions. For PKCS #12 files, the extension is .pfx in Windows and .p12 in Mac OS. You need the
digital ID password (if any) to complete this task.
