the one in id_rsa is your private key, the one uploaded to Github is the public key. – Sathya Apr 9 '13 at 10:57

You can't :) because the key you need on your side is your private key which you never uploaded to github. If you have lost it, it is not a problem, you can simply generate a new key on your system and upload the public part to github.
