Encrypting PDF document and adding digital signature
Selecting [PDF] or [Compact PDF] as a file type when distributing a scanned document or document saved
in a User Box allows you to enhance security for the PDF document by encrypting it using a password or the
digital ID of a user (public key).
When a device certificate is registered in the MFP, a PDF document can be distributed with a digital signature
added. Adding a digital signature certifies the author (MFP) of the sent document and guarantees that the
document has not been modified after being signed.
