21 Encryption and Digital Signature Settings 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. Types of Certificate / Types of Encryption Encrypting HTTP communications from a client to the machine (SSL/TLS server) Encrypting HTTP communications from the machine to a remote server (SSL/TLS client) Encryption using IPSec E-mail encryption/digital signature PDF signature/XPS*2 signature Self-Signed Certificate Certificate Issued by Another CA O O X O X ∆*1 X O O O O :Available ∆ :Set as necessary X :Not available *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). 520
