Why?  Does ebay?  Gmail?  Your ISP?  Paypal?  Etrade?  Other VPS providers?

Yes, guest security requires host security.  Certainly I'd recommend public
keys over password hashes.   If someone can use jack the ripper and produce
useful passwords you're doing something wrong.

don't trust anyone else you have to do it yourself, of course that means
running your own network, physical space, servers, DNS, etc.
