The different versions of keepass have always confused me -- what's the difference between 1 and 2, and why are both around? What's KeePassX, which is linked on the Download page for Linux, and does it support YubiKeys as well? Other than all the confusion that surrounds it, keepass looks quite good to me.
This link may help clear up the confusion between KeePass 1 and 2. (http://keepass.info/compare.html). As for the KeePassX, this was a port from the Windows KeePass 2 to mac OS X. But has now become its own program. I do not know if YubiKeys will work with it.
