Sign presentations digitally
Overview
Sign a presentation using a certificate and save the signature with a supported presentation format. The signature records information such as the certificate, signing time and comments. Apply it after finishing edits, because later processing can remove the signature.
FAQ
Does the signature protect every property in the file?
Its coverage has limits, including document-property parts. Signature validity is not a blanket guarantee that every byte or property is unchanged.
