❏ Self-signed Certicate
is is a certicate that the scanner 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.
Conguring
a CA-signed
Certicate
Obtaining a CA-signed Certicate
To obtain a CA-signed certicate, create a CSR (Certicate Signing Request) and apply it to certicate authority.
You can create a CSR using Web Cong and a computer.
Follow the steps to create a CSR and obtain a CA-signed
certicate
using Web
Cong
. When creating a CSR using
Web Cong, a certicate is the PEM/DER format.
1. Access Web
Cong
, and then select the Network Security tab. Next, select SSL/TLS >
Certicate
or IPsec/IP
Filtering > Client Certicate or IEEE802.1X > Client Certicate.
Whatever you choose, you can obtain the same certicate and use it in common.
2. Click Generate of CSR.
A CSR creating page is opened.
3. Enter a value for each item.
Note:
Available key length and abbreviations vary by a certicate authority. Create a request according to rules of each
certicate authority.
4.
Click OK.
A completion message is displayed.
5. Select the Network Security tab. Next, select SSL/TLS > Certicate, or IPsec/IP Filtering > Client
Certicate or IEEE802.1X > Client Certicate.
6. Click one of the download buttons of CSR according to a specied format by each certicate authority to
download a CSR to a computer.
c
Important:
Do not generate a CSR again. If you do so, you may not be able to import an issued CA-signed Certicate.
7. Send the CSR to a certicate authority and obtain a CA-signed Certicate.
Follow the rules of each certicate authority on sending method and form.
8. Save the issued CA-signed Certicate to a computer connected to the scanner.
Obtaining a CA-signed
Certicate
is complete when you save a
certicate
to a destination.
