RSA keys are generated in pairs: one public RSA key and one private RSA key. If the device already has
RSA keys, a warning and prompt to replace the existing keys with new keys is displayed.
The maximum supported size for the RSA key is 2048 bits.
This command is not saved in the startup configuration; however, the keys generated by this command
are saved in the running configuration, which is never displayed to the user or backed up to another
device.
This command may take a considerable period of time to execute.
