Using a Digital Certicate
About Digital
Certication
❏ CA-signed
Certicate
is
is a
certicate
signed by the CA
(Certicate
Authority.) You can obtain it to apply to the
Certicate
Authority. is certicate certies the existence of the printer is and used for SSL/TLS communication so that
you can ensure the safety of data communication.
❏ CA Certicate
is is a certicate that is in chain of the CA-signed Certicate, also called the intermediate CA certicate. It is
used by the web browser to validate the path of the printer's certicate when accessing the server of the other
party or Web Cong.
For the CA Certicate, set when to validate the path of server certicate accessing from the printer. For the
printer, set to certify the path of the CA-signed Certicate for SSL/TLS connection.
You c a n o b t a in t h e C A
certicate
of the printer from the
Certication
Authority where the CA
certicate
is
issued.
Also, you can obtain the CA certicate used to validate the server of the other party from the Certication
Authority that issued the CA-signed
Certicate
of the other server.
❏ Self-signed Certicate
is is a certicate that the printer signs and issues itself. It is also called the root certicate. Because the issuer
certies itself, it is not reliable and cannot prevent impersonation.
Use it when making the security setting and performing simple SSL/TLS communication without the CA-
signed Certicate.
If you use this certicate for an SSL/TLS communication, a security alert may be displayed on a web browser
because the certicate is not registered on a web browser. You can use the Self-signed Certicate only for an
SSL/TLS communication.

certicate,
create a CSR
(Certicate
Signing Request) and apply it to
certicate
authority.
You can create a CSR using Web Cong and a computer.
Follow the steps to create a CSR and obtain a CA-signed certicate using Web Cong. When creating a CSR using
Web Cong, a certicate is the PEM/DER format.
