I have been playing around with some files in my phones framework and I came across some certificates embedded into my stock rom....

The certificates all seem to be authenticity markers from the different people involved directly with the preparation and release of software to the phone that I have right now....

Just seeing if anyone could drop some knowledge on how a factory update is signed or a factory rom is signed...
