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.
