2. The device certificate and public key are sent from the machine to the user's computer.
3. The shared
key created with the computer is encrypted using the public key, sent to the machine, and
then decrypted using the private key in the machine.
4. The shared key is used for data encryption and decryption, thus achieving secure transmission.
Configuration flow (self-signed certificate)
1. Creating and installing the device certificate
Install the device certificate using Web Image Monitor.
2. Enabling SSL
Enable the "SSL/TLS" setting using Web Image Monitor.
Configuration flow (certificate issued by a certificate authority)
1. Creating the device certificate
Create the device certificate using Web Image Monitor.
The application procedure after creating the certificate depends on the certificate authority.
Follow the procedure specified by the certificate authority.
2. Installing the device certificate
Install the device certificate using Web Image Monitor.
3. Enabling SSL
Enable the "SSL/TLS" setting using Web Image Monitor.
• To confirm whether SSL configuration is enabled, enter "https://(the machine's IP address or host
name)/" in your Web browser's address bar to access this machine. If the "The page cannot be
displayed" message
appears, check the configuration because the current SSL configuration is invalid.
• If you enable SSL for IPP (printer functions), sent data is encrypted, preventing it from being intercepted,
analyzed, or tampered with.
Creating and Installing the Self-Signed Certificate
Create and install the device certificate using Web Image Monitor. For details about the displayed items
and selectable items, see Web Image Monitor Help.
This section explains the use of a self-signed certificate as the device certificate.
1. Open a Web browser.
2. Enter "http://(the machine's IP address or host name)/" in the address bar.
When entering an IPv4 address, do not begin segments with zeros. For example: If the address is
"192.168.001.010", you must enter it as "192.168.1.10" to connect to the machine.
