The RSA key-pair entry. The entry specifies the key-pair
name, size, whether it is exportable and the filename
where the key-pair is stored. Each entry corresponds
to a RSA key-pair generated internally in the device or
imported from outside. When a new entry is created, a
new RSA key-pair is generated in the device and stored
in a corresponding file. When an entry is deleted through
row deletion, the corresponding key-pair is destroyed. The
entry is not allowed to be modified after creation as a
key-pair is not modifiable after its generation.
