Flow for setting
The flow for setting differs depending on which certificate is to be used as the security certificate used for the
HTTPS communication, either the server certificate or the self-signed certificate.
Generate the CRT key.
Generate the self-signed certificate.
Acquire the server certificate.
Generate the signing request.
When using the server certificate
When using the self-signed certificate
Install the certificate.
Set the HTTPS port number.
Select the connection method.
Click [Set].
Note
f
When using the server certificate, the procedure from application to the certification organization to issuing of the server certificate is
required to be performed between the customer and the certification organization. For the application method, etc., contact the certification
organization.
Generating the CRT key
Generate the CRT key used for encryption with the RSA (Rivest-Shamir-Adleman cryptosystem) public key
encryption method. CRT key is a type of the private key.
1) Click [Https set up]
→
[CRT Key generate]
→
[Execute].
f
The page to generate the CRT key is displayed.
2) Click [Execute].
f
The CRT key is generated.
f
Once the generation of the CRT key is completed, the key length and the generation date and time of the
current CRT key are displayed in [RSA key size] and [Last modified] of [Current CRT key] at the upper row.
3) Click [back].
Note
f
[Not generated] displayed in [Last modified] indicates that the CRT has not been generated.
f
[RSA key size] is fixed to [2048bit]. The server certificate may not be issued depending on the certification organization to apply if the key
length is 2048-bit.
