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.

Tips

  • To use this function, an option is required. For details on the required option, refer to [Scan options] .

  • Before using this function, register a user's digital certificate for encryption in the E-mail address of this machine. To register a certificate, use Web Connection. For details, refer to [Registering E-mail Address] .

  • When [Searchable PDF] is specified together, if [Adjust Rotation] is set to ON in [Searchable PDF], it fails in an encryption with a digital certificate. [Adjust Rotation] is set to ON in the default settings; therefore, change the setting.
