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.

Reference

-

Using PageScope Web Connection, you can encrypt and add a digital signature to send a document
in a User Box to another device in the PDF format.

-

To add a digital signature, it is necessary to encrypt the PDF document using a password or digital ID.
