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.
Note • If the certificate for the SSL server contains the V3 extension "keyUsage", "digitalSignature" must be
asserted. Refer to "How to check the certificate settings on Windows" (P.411).
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).
For information on the setting procedure, refer to "Configuration of HTTP Communications Encryption" (P.415).
