Well... It depends on your needs.
If you are looking for a tough encryption (this brings performance
degradation), then you could use Certificates \ Asymmetric Keys,
If you are looking for an encryption (which is not as powerful as the
previous ones) which does not affect performance as much as the others, then
you could Symmetric Keys.
It's your choice. But both of them asks for a sacrifice from your system.

Well, I do not know the possible workload on your server so I don't have any
clue about how it is going to work.
I suggest you to install R2 to your Windows Server 2003 if you have not.
Good luck!
