Adding missing keys to Developer ID Application and Developer ID certificates for desktop Macs to sell app outside the app store

I have been unable to add the missing keys to Developer ID Application and Developer ID Installation. The keys were on my computer two weeks ago. In an effort to reinstall the missing keys, I have accidentally created 3rd Party Mac Developer Application and 3rd Party Mac Developer Installer certificates, which are used for Apple App store for Mac.


I have talked with Apple this morning but the material they sent me has not helped. I even developed an non-functioning app in X Code and used automatic signing but I could not revoke Developer ID Application and Developer ID Installation to reinstall them with their keys.

Any help you provide me would be greatly, greatly appreciated!
