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 enabled.
To encrypt the login password, specify the driver encryption key on the machine and on the printer driver installed on the user's computer.
Password for IPP Authentication
To encrypt the IPP Authentication password using Web Image Monitor controlled from networked computers, set "Authentication" to [DIGEST], and then specify the IPP Authentication password set on the machine. (Web Image Monitor is a management tool installed on this machine to monitor this machine or configure settings for this machine by using a web browser.)
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 SNMPv3 Encryption.
