To decrypt the files which are unpacked using the tool, the key is available under PS Vita Keys

Structure

It is not complete but here you can see the basic structure:

Regioning

If simular to PS3, then there is no regioning in the .PUP files, they are the same for all different regions.
The PS Vita however gets the psp2-updatelist.xml from different servers, depening on the region of that model.
