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).
Encrypting HTTP Communications from the Machine to a Remote Server
(SSL/TLS Client)
The SSL/TLS protocol is used to encrypt the HTTP communications between a remote
server and the machine.
No certificate is required in general. However; if a remote server is set to require an SSL
client certificate, you can use a certificate issued by another CA.
When verification of server certificates is enabled to verify the SSL/TLS certificate of a
remote server, import a certificate issued by another CA using
Dell Printer Configuration
Web Tool
to the machine.
Encryption using IPSec
IPSec enables IP-level (not application-level) encrypted communications with remote
devices.
If you select
Digital Signature
for
IKE Authentication Method
, a certificate issued by
another CA is required.
If you select
Preshared Key
, no device certificate is required.
NOTE:
•
If the certificate for IPSec contains the V3 extension (keyUsage), "digitalSignature" bit must be
asserted.
To verify the certificate of the remote device, you must register a root certificate created
by a CA of the remote device on the machine.
NOTE:
•
To use certificates that have already been created, import them with
Dell Printer Configuration
Web Tool
.
Configuration of HTTP Communications Encryption
This section describes the settings to encrypt HTTP communications.
Step 1 Configuration on the Machine
Configure a certificate on the machine. When
Automatic Self-Signed Certificate
Creation
is set to
On
, a self-signed certificate is automatically created as the SSL server
certificate. If necessary, import a certificate issued by another CA.
NOTE:
• Automatic Self-Signed Certificate Creation
is set to
On
by default.
The following describes the procedures to set up a certificate by
Dell Printer
Configuration Web Tool
.
