First look at PS5 digital content distribution system
« on: October 23, 2020, 03:19:23 AM »
I was able to obtain the pkg url for Share Factory Studio, a free application for PS5 available on the Playstation new webstore.

https://sgst.prod.dl.playstation.net/sgst/prod/00/np/PPSA01280_00/d8ec167a-59da-4e54-8e2c-1161c706516a-version.xml

The UUID in the URL is identical on two different accounts. We can infer several things from this:

1. Digital content is distributed without authentication, same as previous platforms.
2. Application and patch distribution are merged. It is no longer possible to obtain the base version application after a patch has been released.
3. It will no longer be possible to compute the update url from the title ID, instead a random UUID is used.

The json manifest in the xml contains two split files. However they are not the same file split along 4GiB boundaries. The first file has magic {0x7F, 'F', 'I', 'H'}, previously not seen. The second file has magic {0x7F, 'C', 'N', 'T'}, same as PS4 pkgs.
