Authenticating to a DB with a key?

Is a VPN not an option? Assuming this is on a budget and no additional
hardware can be used you could use OpenVPN or even good ol' IPSEC from box
What about SSH + keys + tunneling?
It might also help to know a bit more about the use case.
Are we talking about you interacting with the database via a GUI client,
shell client? Or are we talking about an application on some other server
that needs to connect to the database over the Internet? Maybe both?
It might be wise if you can to use additional hardware or at least not just
rely on SSL/TLS libs tied to your database. Even if someone couldn't get
authenticated because they have a bad certificate they could DDOS your DB
server pretty easily by throwing lots of SSL/TLS negotiations attempts at
it. Or depending on how the SSL/TLS connection handler on your database
works it might be that you are using up a database connection with every
connection attempt even if it fails. Of course some iptables rate rules
would help this.
