Encrypting Transmitted Passwords
Configuring the driver encryption key and password encryption for IPP authentication enables
communication with encrypted passwords as well as increasing the security against password cracking.
In order to further enhance security, we recommend using IPsec, SNMPv3 and SSL/TLS all together.
Also, encrypt the login password for administrator authentication and user authentication.
Driver Encryption Key
This key is a character string used for encrypting login passwords or document passwords sent from
each driver when user authentication is ON.
To encrypt the login password, specify the driver encryption key on the machine and on the printer
driver installed in the user's computer.
Password for IPP Authentication
To encrypt the IPP Authentication password on Web Image Monitor, set "Authentication" to
[DIGEST], and then specify the IPP Authentication password set on the machine.
You can use telnet or FTP to manage passwords for IPP authentication, although it is not
recommended.
• For details on encrypting the login passwords used for administrator authentication, see page 19
"Registering and Changing Administrators".
Specifying a Driver Encryption Key
Specify the driver encryption key on the machine.
This setting enables encrypted transmission of login passwords and strengthens the security against
password cracking.
