modify_algorithms and password?

I am trying to use this in a new application, but I need to modify the algorithms for the connection, and I can't work out how to add these parameters to the connection.

In :SSH I would do something like this:

modify_algorithms: [
        {:append, [{:kex, [:"diffie-hellman-group-exchange-sha1"]}]},
        {:append, [{:public_key, [:"ssh-rsa", :"ssh-dss"]}]}
      ]

I also need to use password based auth for this, so similarly need to supply a password.

Are these things possible with this framework, I can't find anything in the docs?

Thanks

No files, tests, or entry points are named. Start by locating how connection options and authentication are documented and passed, then determine whether modify_algorithms and password-based authentication are supported; done means both requested SSH options can be configured and the documentation explains their use.
