[Somewhat OT] Mac Code Signing - can anyone explain?

[Graham Samuel]

I wrote an earlier mail on this subject. Good thing nobody replied, since I more or less worked it out myself. I have now generated a couple of certificates (app and installer), so I should be able to do the code signing. However, in my Keychain Access under “My Certificates” I have a lot of folders all with the same name - com.apple.kerberos.kdc - each containing a file (key) with the same name again! How am I supposed to distinguish one from another, or don’t I have to? The Apple Developer Portal warns me to keep copies of my certificates and public and private keys, but I don’t see how to find out which ones I generated just now and which ones are just old.

It would be great to hear from someone who knows.
