Creating and installing a certificate 12

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 self-signed

certificate on page 134.

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 146.

• When importing a certificate and a private key. See Import and export the certificate and private

key on page 148.

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 149.

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.

aStart your web browser.

bType http://printer_ip_address/ into your browser. (Where printer_ip_address is the IP

address or the print server name)

For example:

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

Note

If you have edited the hosts file on your computer or are using a Domain Name System, you can also enter

the DNS name of the print server. As the print server supports TCP/IP and NetBIOS, you can also enter

the NetBIOS name of the print server. The NetBIOS name can be seen in the printer settings page. The

NetBIOS name assigned is the first 15 characters of the node name and by default it will appear as

“BRNxxxxxx” where “xxxxxx” is the last six digits of the Ethernet address.
