IOS Certificate / Provisioning Profile - missing tutorial


I successfully created a IOS Certificate / Provisioning Profile for a development IPK. Now I want to do the same for production an distribution in the apple app store, but the tutorial only covers the developer part:

What do I need to do in order to get a provisioning profile? I’m stuck at the point where the tutorial says I should export the certificate from the keychain. When I right-click on it, there’s no “export option” like the one I had in the development tutorial.

Any hint how to fill these fields now?

well OK, I found a first hint here:

but I still get no .p12 option…
