RSA Keys Window
Key Data
Click to view a selected RSA key.
Save Key to PC Button
Click to save the data of the selected key to your PC.
Generate RSA Key Pair
Use this window to generate a new RSA key pair.
Label
Enter the label of the key in this field.
Modulus
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 great er 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.
Type
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.
Key is exportable checkbox
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.
