Creating/Registering/Changing a Key and Its Certificate

To use the SSL encrypted communication function for IPP printing or the Remote UI, the settings for the public key for encryption, private key for decryption, and certificate for the users to confirm key information are required.

See the following according to your system environment and the options that you want to specify.

When creating and using a key and its certificate with this printer

Newly Creating a Key and Its Certificate

Newly create a key pair (the public key and private key) and its certificate.

Specifying a Key as the Default Key

Specify a created key to be used for SSL encrypted communication.

Checking a Certificate

Confirm the contents of the certificate of a created key.

Erasing a Key and Its Certificate

Erase a created key and its certificate.

When using a key/certificate file created by a device other than this printer

Installing a Key/Certificate File on the Printer

Install a key/certificate file created by a device other than this printer on this printer.

Registering a Key and Its Certificate in the Printer

Register a key pair (the public key and private key) and its certificate in a key/certificate file installed on this printer so that you can use them in the printer.

Specifying a Key as the Default Key

Specify a registered key to be used for SSL encrypted communication.

Checking a Certificate

Check the certificate of a registered key.

Erasing a Key and Its Certificate

Erase a registered key and its certificate.

Erasing a Key/Certificate File Installed on the Printer

Erase a key/certificate file installed on this printer from this printer.

IMPORTANT
The number of key and certificate which you can create, register, or install Only one key and certificate pair can be created, registered, or installed. If you cannot create, register, or install a key and its certificate, delete unnecessary ones. About a Key/Certificate File which can be installed on this printer Only PKCS#12 files in which the key's algorithm is "RSA" and the extension is ".P12" can be installed.

NOTE
SSL encrypted communication function This is a function that enables exchange of encrypted data between this printer and a computer when performing IPP printing in which data is printed via a network or when using the Remote UI in which you manage the printer with the web browser. Using the SSL encrypted communication function achieves safer printing environments by preventing theft and falsification of data. To perform SSL encrypted communication A key pair (the public key for encryption and private key for decryption) is required. Registering the key pair in this printer and opening the public key to the users allows you to perform the following. The users can encrypt data to send to the printer. Only this printer can decrypt the encrypted data with the private key. In this printer, a certificate is also created when a key pair is created. The users can check information about the key with the certificate.
