Ssh provides host authentication.

You can encrypt things with file transfer using the -c switch of scp.

Yes, ssh is a bit limited. I think SSL (secure socket layer) is the
better solution. I have been arguing with myself whether to use SSL or
SSH, and because of the ease of non-root installation/use, I chose
SSH. Think I should switch to SSL...
