Using a Digital Certicate
About Digital Certication
❏ CA-signed Certicate
is is a certicate signed by the CA (Certicate Authority.) You can obtain it to apply to the Certicate
Authority. is certicate certies the existence of the printer is and used for SSL/TLS communication so that
you can ensure the safety of data communication.
❏ CA Certicate
is is a certicate that is in chain of the CA-signed Certicate, also called the intermediate CA certicate. It is
used by the web browser to validate the path of the printer's certicate when accessing the server of the other
party or Web
Cong.
For the CA Certicate, set when to validate the path of server certicate accessing from the printer. For the
printer, set to certify the path of the CA-signed Certicate for SSL/TLS connection.
You can obtain the CA certicate of the printer from the Certication Authority where the CA certicate is
issued.
Also, you can obtain the CA certicate used to validate the server of the other party from the Certication
Authority that issued the CA-signed Certicate of the other server.
❏ Self-signed Certicate
is is a certicate that the printer signs and issues itself. It is also called the root certicate. Because the issuer
certies 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
Certicate
.
If you use this
certicate
for an SSL/TLS communication, a security alert may be displayed on a web browser
because the certicate is not registered on a web browser. You can use the Self-signed Certicate only for an
SSL/TLS communication.
