Navigation: Server > Settings > SSH Host Key Manager |

SSH host key is used for SFTP connection (not for the SSH public key authentication).

Click "Add SSH Host Key" button to add an SSH host key. First you need to specify a key name, then you can choose a SSH host key from your hard disk.

If you do not have any SSH host key, just click the "Create Host Key File" button and create a SSH host key then.
