Add (.CER) File association for IOS

I had a problem to add a file association that was resolved here, and now, it seems that the iOS reserve the 'cer' type, what i really need is to copy the .key and .cer (along with a password) in my app, i suceded into getting the .key to be opened by the app, but no matter what i do, the .cer always open with Settings.app.

What i want to do is offer iTunes File Sharing and Mail for adding those resources.

Has anyone experi开发者_JAVA百科enced this? is there a way to open the cer in a custom app?

Seems that is not possible (At least for ios4), had to use iTunes File Sharing, something else you can do is compress as a zip and load in your app (it might come in handy if you also need to copy other files along with it as a whole)
