> It would be good to be able to enforce a public host key check against a known value when making a SSH or SFTP connection.
> Currently, people are forced into using
> {code:java}
> 'no_host_key_check' = True{code}
> which could allow a Man-in-the-middle attack.
> There are two components as far as I can see:
>  * The connection should support specify the key_type and key (either as fields or in extra)
>  * The hook should write get and write those values (along with the hostname) to the ~/.ssh/known_hosts file if
> {code:java}
> 'no_host_key_check' = False{code}
