Signing Certificates - training/course?

I am sitting with a lot of inhouse IOS apps and would really like to get some deeper knowledge on all the developer backend where provision profiles etc is created - and there exist so many different options that I would like to get a some info on and in general best practise on signing


I simply cannot find any course/training options on this subject ? - I am not a developer (and will never be), but just getting a deep knowledge on signing is what I need.


Anyone know where to some training/course is available
