By default, the paramiko.SSHclient sets the policy to the RejectPolicy. The policy rejects connection without validating as we saw above. Paramiko does however give you a way to sort of “Trust all” key policy, the AutoAddPolicy. Parsing an instance of the AutoAddPolicy to set_missing_host_key_policy () changes it to allow any host.

What can paramiko do with hostkeys object?

Get the local HostKeys object. This can be used to examine the local host keys or change them. the local host keys as a HostKeys object. Return the underlying Transport object for this SSH connection. This can be used to perform lower-level tasks, like opening specific kinds of channels.
