H3C S6812 Series Command Reference Manual page 1958

To distribute a local RSA host public key to a peer device:
1. Save the exported local host public key to a file by using one of the following methods:
Use the public-key local export rsa [ name key-name ] { openssh | ssh2 } command to

export the key, and then copy and paste it to a file.
Use the public-key local export rsa [ name key-name ] { openssh | ssh2 } filename

command to export key to a file. You cannot export the key to the folder pkey or its
subfolders.
2. Transfer a copy of the file to the peer device, for example, by using FTP in binary mode or TFTP.
For more information about FTP and TFTP, see Fundamentals Configuration Guide.
3. On the peer device, use the public-key peer import sshkey command to import the host
public key from the file.
Choose the correct public key format that is supported on the device where you import the host
public key. In FIPS mode, the device only supports SSH 2.0 and OpenSSH.

# Export the host public key of the local RSA key pair with the default name in OpenSSH format to
the file key.pub.
