Distributing a local host public key
You must distribute a local host public key to a peer device so the peer device can perform the
following operations:
• Use the public key to encrypt information sent to the local device.
• Authenticate the digital signature signed by the local device.
To distribute a local host public key, you must first export or display the key.
• Export a host public key:
ï‚¡ Export a host public to a file.
ï‚¡ Export a host public key to the monitor screen, and then save it to a file.
After the key is exported to a file, transfer the file to the peer device. On the peer device, import
the key from the file.
• Display a host public key.
After the key is displayed, record the key, for example, copy it to an unformatted file. On the
peer device, you must literally enter the key.
