Moving Xcode certificate to new system for iPhone Dev

Question

In Apple's Provisioning Portal "How To" under Certificates, there is a section called "Saving your Private Key and Transferring to other Systems". Now this is what I'm doing (I have rebuilt my machine with a new HDD and therefore have access to my previous OS build) and I'm looking to backup my private key so I can install it on my new OS build and start codesigning iPhone Applications again.

The problem is, in the how to, it says to backup the "<First Name> <Last Name> public certificate that is paired with it." (although the image is a private key):

And so when I checked my KeyChain, I've found 9 Private keys and 9 Public keys with my name on, so how do I know what I'm looking for?

I found in the first private key, it has this access control:

But when importing this I get a message saying it cannot import :(

So really, I just want to know which one I need to import - I guess I can try trial and error with them but would like to know either way.

Answer 1

You click on the small triangle at the left of the key and the one that has "iPhone Developer:"First Name" "Last Name" as a child is the one you want.

BTW, it's Xcode, not xCode :-).
