This tool can check whether the PKG was signed by Sony (pre-PS4), and whether it is corrupted or not.
Simply drag-and-drop files and/or folders you want to check onto the executable. Alternatively if you prefer to run from console, just supply paths you want to check.
PKG Validator presents result in three columns: Header, Metadata, and Package.
Header and Metadata validate if the PKG is authentic and was produced by Sony,
it does this by calculating various security values that are present in the
file structure.
Most PKGs have several levels of layered protection that are designed to make sure
that nothing was modified. Any result other than green ok or yellow idu means
that the PKG wasn't made by Sony, and nothing more.
Package on the other hand is a simple full file content hash validation
that tells if it was corrupted in the transfer or not. It does not care
if the file was produced by Sony itself, or made with homebrew tools.
You want this to be green ok for all your PKGs, always.
