About Encryption
Data can be encrypted for communication between the printer and computers over a
network.
Encryption of client-to-printer HTTP communication (SSL/TLS
server)
Enabling the SSL/TLS communication feature of the printer makes it possible to encrypt
HTTP communication between the printer and computers over a network.
Ports that use the printer's HTTP server are the SOAP port, Internet service (HTTP) port,
and IPP port.
SSL/TLS protocol is used for encryption of HTTP communication between a client and the
printer.
The SSL/TLS server certificate used by the SSL/TLS server can be either a previously
created certificate or a certificate created using CentreWare Internet Services.
Note
• To use a previously created certificate, use CentreWare Internet Services to import it. For more
information, refer to the online help for CentreWare Internet Services.
• Encrypting HTTP communication makes it possible to encrypt communication data (SSL encrypted
communication) when printing with the IPP port.
• An issued certificate is valid for 1 year.
Encryption of printer-to-external-server HTTP communication (SSL/
TLS client)
SSL/TLS protocol is used for encryption of HTTP communication between an external
server and the printer.
Normally it is not necessary to configure certificate settings. However, if an external server
is configured to request authentication of an SSL client, you will need to use CentreWare
Internet Services to import the printer's existing SSL/TLS client certificate and configure its
settings.
Also, to perform certificate validation and validate the external server, you need to validate
the external server's SSL/TLS server certificate by registering its root certificate on the
printer from CentreWare Internet Services.
Note
• Refer to the online help for CentreWare Internet Services for information about how to use it to import an
existing certificate.
Encryption Using IPSec
IPSec can be used to encrypt communications with the printer.
An IKE authentication pre-shared key or digital signature can be selected with the printer.
A printer IPSec certificate is required in order to select a digital signature.
Use CentreWare Internet Services to import the existing IPSec certificate.
Note
• If the certificate being imported as an IPSec certificate has a V3 extension (KeyUsage), the digital
signature bit setting must be set on.
