NAX0 archive encryption notes (Nintendo Switch)

I downloaded the Snipperclips demo to see how Nintendo Switch stores game/app data on micro sd. I then deleted the data and re downloaded it to see if the filenames would change. The folders and filenames are the same as the first go. https://pastebin.com/53kL3CUV

I did notice, however the NAX0 archive data was different then the original. The only thing which remained the same was file size. The first go only had extra data in the last two files(partial jpg thumbnail data). The second try had random data in the NAX0 archive header for most of the files.
