Creating and installing a certificate

14

The Brother print server allows you to use SSL/TLS communication by configuring a certificate and 
corresponding private key. This print server supports two certification methods. A self-signed certificate and 
a certificate that is issued by a CA (Certificate Authority).

„

Using self-signed certificate
This print server issues its own certificate. Using this certificate, you can easily use the SSL/TLS 
communication without having a certificate from a CA. See 

Creating and installing a self-signed certificate

 

on page 143.

„

Using a certificate from a CA
There are two methods for installing a certificate from a CA. If you already have a CA or if you want to use 
a certificate from an outside trusted CA:

• When using a CSR (Certificate Signing Request) from this print server. See 

Creating CSR and installing 

a certificate

 on page 155.

• When importing a certificate and a private key. See 

Import and export the certificate and private key

 on 

page 157.

Note

• If you are going to use SSL/TLS communication, we recommend that you contact your system 

administrator before using.

• This print server stores only one pair of a certificate and a private key that you installed or previously 

imported. This printer overwrites the certificate and the private key if you install a new one.

• When you reset the print server back to its default factory settings, the certificate and the private key that 

are installed will be deleted. If you want to keep the same certificate and the private key after resetting the 
print server, export them before resetting and re-install them. See 

How to export the certificate and private 

key

 on page 158.

 

This feature can be configured using Web Based Management (web browser) only. Follow these steps to 
access the configure certificate page using Web Based Management.

a

Start your web browser.

b

Type “http://printer’s IP address/” into your browser. (where “printer’s IP address” is the printer’s IP 
address or the node name.)

„

For example:

http://192.168.1.2/ 

(if the printer’s IP address is 192.168.1.2.) 

http://BRN123456/ 

(if the printer’s node name is BRN123456.)
