Generating Key Pairs
The key pair required for encrypted communication via Secure Sockets Layer (SSL) can be generated with the machine. You can use SSL when accessing the machine via the Remote UI. Up to three key pairs can be registered on the machine.
1
Start the Remote UI and log on in System Manager Mode. Starting the Remote UI
2
Click [Settings/Registration].
3
Click [Security Settings] 
[Key and Certificate Settings].
[Key and Certificate Settings].
4
Click [Generate Key].
To delete a registered key pair
On the right side of the key pair that you want to delete, click [Delete] [OK].
[OK]. A key pair cannot be deleted when "SSL" is displayed under [Key Usage], indicating that the key pair is currently in use. In this case, disable SSL or replace the key pair with another. You will then be able to delete it.

Specify settings for the key and certificate.
[Key Settings][Key Name]
Enter up to 24 alphanumeric characters for naming the key pair. Set a name that will be easy for you to find later in a list.

[Signature Algorithm]
Select the signature algorithm from the drop-down list.
Select the signature algorithm from the drop-down list.
[Key Algorithm]
The algorithm used to generate keys is RSA. Select the key length from the drop-down list. The larger the number for the key length, the slower the communication. However, the security is tighter.
[512-bit] cannot be selected for the key length, if [SHA384] or [SHA512] is selected for [Signature Algorithm].

[Validity End Date (YYYY/MM/DD)]
Enter the last date of validity of the certificate in year/month/day format in the range 1 January 2000 to 31 December 2037. A date earlier than the [Validity Start Date (YYYY/MM/DD)] cannot be set.

Click [OK].
A key pair may take approximately 10 to 15 minutes to generate.
After a key pair is generated, it is automatically registered to the machine.
