2Securing communications with Secure Shell


To minimize detection by a target network during testing, Kali does not enable any externally-listening network services. Some services, such as Secure Shell (SSH), are already installed. However, they must be enabled prior to use. Kali comes preconfigured with default SSH keys. Before starting the SSH service, it’s a good idea to disable the default keys and generate a unique keyset for use. Move the default SSH keys to a backup folder, and then generate a new SSH keyset using the following command:

dpkg-reconfigure openssh-server

The process of moving the original keys and generating the new keyset is shown in the following screenshot:

To confirm that the newly generated keys are distinctive, calculate their md5sum hash values, and evaluate with the unique keys as proven within the following screenshot:
