9.7 Specifying a user-defined encryption passphrase
The machine and the printer driver communicate with each other by encrypting a user password, account
password or secure document password using a common encryption key.
Although an encryption passphrase for generating the encryption common key is preset as a default setting,
it can also be generated with a user-defined encryption passphrase.
When specifying a user-defined encryption passphrase, specify the same encryption passphrase for the
machine and the printer driver.

Note
If different values are used for the encryption passphrase for the machine and the printer driver, the
machine cannot decrypt the encrypted user password, account password or secure document
password. Then printing cannot be performed.
The encryption passphrase automatically generates the common encryption key. The common
encryption key cannot be specified directly.
