Hello CC, Since his recent PS4Orbis Title Metadata Database release, PlayStation 4 developer @RedEyeX32 made available on Twitter a PS4 PKGDec homebrew tool used to decrypt encrypted entries within a package file container.
:ninjaxf2:
In his Tweets below, he notes "The keys to decrypt these entry files are encrypted with RSA. I've provided the necessary keys but you will need to calculate the rest to make the tool useful."

Also from him are some PS4 private and public key SHA-256 hashes, as the PlayStation 4 v1.76+ sceneeagerly awaits further word of SpecterDev's progress on a public v4.05 kernel exploit that can be used to jailbreak newer PS4 console models.
Remove the last 16 bytes from the included keys within the source to get the actual 'key' of E, P, & Q.
To calculate public key: n = q * p
To calculate private key: d = e^-1 mod ((p - 1) * (q - 1))
