Encryption Service Overview
You may have to purchase the Security Kit option to enable encryption with your printer. If you cannot
generate a self-signed certificate, or enable SSL/TLS Communication, as stated under Configuration of
HTTP Communication Encryption, in this section, contact your Xerox Representative to purchase the
option.
The communication data between the printer and computers on a network can be encrypted.
Encryption for the printer is set up using CentreWare Internet Services. Note that the quickest and
easiest, although not the most trusted, method to use to set up initial HTTP communication encryption
is the generation of a self-signed certificate. Click Printer Digital Certificate Management in the
Security folder on the Properties page of CentreWare Internet Services. Use this to manage all the
digital certificates, of various types, stored on the printer.
Types of Encryption Services Available
Encryption of HTTP Communications from a Client to the Printer (Server Certificate)
The SOAP port, Internet service (HTTP) port, IPP port, and WebDAV port use the HTTP server of the
printer.
The SSL/TLS suite of protocols is used in the encryption of HTTP communications from a client to the
printer. A user of a client computer accesses the printer’s HTTP server by typing https://, followed by
the IP address of the printer, into the Address box of a Web browser application. The printer then offers
the client a Digital Certificate, which the client accepts (after reviewing the validity of same). Upon
acceptance of the Digital Certificate, a Public Key exchange takes place, encryption algorithms are
agreed upon between the two parties, and the client uses the server’s Public Key to communicate with
the server using digitally signed and encrypted data.
Digital certificates imported from a Certificate Authority, or self-signed certificates created with
CentreWare Internet Services, can be used as SSL/TLS certificates on the printer’s HTTP server.
Encryption of HTTP Communications from the Printer to a Remote Server (Client Certificate)
The SSL/TLS suite of protocols is used to encrypt HTTP communications with a remote server.
No client certificate is typically required for this activity. However, if a remote server is set to require an
SSL client certificate, an SSL/TLS client certificate must be registered on the printer.
Digital certificates imported from a Certificate Authority can be used as SSL/TLS certificates on the
printer’s HTTP server.
Note: When Remote Server Certificate Validation is enabled, under SSL/TLS Settings in CentreWare
Internet Services, the root certificate of the remote server must be registered to the printer (imported
with CentreWare Internet Services) to verify the Digital certificate of same.
