Do not distribute the RSA server public key
serverkey (default)
to a peer device.
Destroying a local key pair
To avoid key compromise, destroy a local key pair and generate a new pair after any of the following
conditions occurs:
•
An intrusion event has occurred.
•
The storage media of the device is replaced.
•
Local certificate has expired. For more information about the local certificate, see "Configuring
PKI."
To destroy a local key pair:

Configuring a peer host public key
To encrypt information sent to a peer device or authenticate the digital signature of the peer device,
you must configure the peer device's public key on the local device.
You can configure the peer host public key by using the following methods:
•
Import the peer host public key form a public key file (recommended).
•
Manually enter (type or copy) the peer host public key.
Importing a peer host public key from a public key file
Before you perform this task, make sure you have exported the host public key to a file on the peer
device and obtained the file from the peer device. For information about exporting a host public key,
see "
After you import the key, the system automatically converts the imported public key to a string in the
Public Key Cryptography Standards (PKCS) format.
To import a peer host public key from a public key file:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Import a peer host public key
from a public key file.
public-key peer

By default, no peer host
public keys exist.
Entering a peer host public key
Before you perform this task, make sure you have displayed the key on the peer device and recorded
the key. For information about displaying a host public key, see "
