rsa local-key-pair create Syntax
rsa local-key-pair create
View
System view
Parameter
None
Description
Using the rsa local-key-pair create command, you can generate the local RSA host
key pair and server key pair.
When this command is used to configure, the system will give alarm and prompt
that former key will be replaced if RSA key has existed. The view of generated key
pair is router name+ server and router name+ host, e.g., 3Com_host and
3Com_server. This command will not be stored in configuration file.
After this command is input, the system will prompt you to enter the digit of host
key. The digit of server key pair should differ from that of host key pair in 128
digits at least. The minimum length of server key pair and host key pair is 512
digits and the maximum length is 2048 digits. If there has been key pair, the user
should confirm whether to change it.
The primary operation to accomplish SSH login is to configure and generate local
RSA key pair. Before performing other SSH configurations, you must accomplish
the configuration of the rsa local-key-pair create command to generate local key
pair. It is necessary to execute this command only once and it is unnecessary to
execute again after the router restarts.
For the related command, see rsa local-key-pair destroy.
Example
Configure and generate local host key pair and server key pair.
[3Com] rsa local-key-pair create
The name for the keys will be: rtvrp_Host
% You already have RSA keys defined for rtvrp_Host
% Do you really want to replace them? [yes/no]:y
Choose the size of the key modulus in the range of 512 to 2048 for
your Keys.
Choosing a key modulus greater than 512 may take a few minutes.
How many bits in the modulus [512]:512
