Thanks to: TheDoc and Dodo - although I know all this stuff, I was hoping to get some idea about database I mean if I use md5 I use it with a key, now if someone hacks into the server and gets the key, he gets the database... But again thanks for your reply!
Now BlackRain - Did I say Hack Proof???
No I didn't I only asked for "Almost unhackable"...
More replies about database are welcomed!
Thanks
