Encryption and Digital Signature Overview
Types of Certificate
To use the Encryption feature and the Signature feature on the machine, a certificate is
required.
The following two types of device certificate can be used on the machine:
• A self-signed certificate created by Dell Printer Configuration Web Tool (The valid period
can be specified from1 to 9,999 days.)
• A certificate issued by another CA
When you use a certificate issued by another CA, import the certificate using Dell Printer
Configuration Web Tool.
*1 :Available when [IKE Authentication Method] is set to [Authenticate by Digital Signature].
*2 :XPS stands for XML Paper Specification.
Encryption Features for Communication
The data sent between the machine and computers on a network can be encrypted.
Encrypting HTTP Communications from a Client to the Machine
(SSL/TLS Server)
The SOAP, Internet Services (HTTP), IPP, and WebDAV ports use the HTTP server of the
machine.
The SSL/TLS protocol is used to encrypt the HTTP communications between a client and
the machine.
To encrypt communications, either one of the device certificate is required: a self-signed
certificate or a certificate issued by another CA.
Note • By encrypting HTTP communications, communications data can be encrypted at the time of printing
using IPP (SSL encrypted communications).
