After the key has been matched. We typically make a backup of the certificate, which is a P12 file.
This p12 file is very useful, it contains not only the information of the CER, but also the private key information, namely: P12 backup file = CER file + private key; So with this p12 there is no need to worry about certificates being lost.

If the development certificate lets Apple believe that you are a legitimate developer, then this license is intended to allow
The real Machine device (IPHONE,IPAD) You are debugging is considered to be a legitimate test device. This license is the trust credential for the device.
When the app is installed on the real machine, the license information in the app and the license in the iphone match, it can be loaded, otherwise it can't be installed.
There are several types of licenses: Develop, version adhoc, AppStore. Here's the adhoc, this version is primarily for internal testing. For example, before the app goes online, it requires an N-round QA test. This is the test for them. Test no problem, then hit the AppStore version, test error after submitting to the Apple Store.
Summarize:
So it is understood that in order to play a beta version that can be installed on the iphone, the developer must have: 1, developer certificate + private key, 2, license file. The two full-license can be packaged successfully.
