Enter the key modulus value. If you want a modulus value between 512 and 1024
enter an integer value that is a multiple of 64. If you want a value higher than
1024, you can enter 1536 or 2048. If you enter a value greater than 512, key
generation may take a minute or longer.
The larger the modulus size, the more secure the key is. However keys with larger
modulus sizes take longer to generate and longer to process when exchanged.
Select the type of key to generate, General Purpose, or Usage. General purpose
keys are used for both encryption and signing of certificates. If you generate
Usage keys, one set of keys will be used for encryption, and a separate set will be
used for certificate signing.
Check if you want the key to be exportable. An exportable key pair can be sent to
a remote router if it is necessary for that router to take over the functions of the
local router.
Check the Save keys to secure USB token checkbox if you want to save the RSA
keys to a USB token connected to your router. This checkbox appears only if a
USB token is connected to your router.
Choose the USB token from the USB token drop-down menu. Enter the PIN
needed to log in to the chosen USB token in PIN.
After you choose a USB token and enter its PIN, click Login to log in to the USB
token.
This window appears when you add or delete credentials, such as an RSA key pair
or digital certificates, that have been saved on a USB token. For the deletion to
take place, you must provide the USB token name and PIN.
