Encrypting PDF Files

This mode enables you to encrypt PDF files that you send to an e-mail address or file server for enhanced security.
If you set a password for a PDF file, only users who enter the correct password can open, edit, or print the file.

For information on the optional products required to use this function, see "Optional Products Required for Each Function."
