How do I get a replacement development certificate's p12 file?

Question

My Mac hard disk crashed, put a new hard disk and reinstalled OS, xcode, but not able to build my app for device target since the certificate does not work any more. I could have used the p12 file but unfortunately I lost it.

So, what's next? How do I update my app which is there in app store? I need to smoke now :(

As a developer you should know better then to not back up your data. For around $100 you can get all the backup disk size you should need for a development box.
