Creating an Encrypted PDF File Using the Digital Certificate

Use a user's digital certificate (public key) to encrypt a PDF file when sending it. An encrypted PDF file can be decoded only with a user's secret key, preventing information from being leaked to a third party.

To encrypt a PDF file with a digital certificate, select [PDF] or [Compact PDF] as the file type, and select [PDF Detail Setting] - [Encryption]. Then, configure the following settings.

Setting	Description
[ON]/[OFF]	Select [ON] to encrypt a file.
[Encryption Type]	Select [Digital ID] to encrypt a PDF file with a digital certificate. [Select Digital ID]: Select an E-mail address that contains a digital certificate for encryption. [Use Recipient's Digital ID]: Uses a digital certificate registered in the PDF file sending destination.
[Encryption Target]	Select the target to be encrypted. Selecting [Other than Metadata] excludes property information specified in [PDF Document Properties] from encryption processing.
