About peer host public key configuration
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 from a public key file (recommended).
Manually enter (type or copy) the peer host public key.
