While many are patiently awaiting further details on the PS4 6.20 Kxploit in development, today PlayStation 4 scene developers @RedEyeX32 via @zecoxao shared Cipher and Hasher PS4 Backup And Restore (BAR) Kernel Keys while 3226:2143 (aka IDC) documented containers referred to as Envelope Files used in encrypting and signing messages.

Based on the current findings, they were likely introduced around PS4 Firmware FW 3.00 (>2.56 <=3.50), noting that the messages are encrypted using AES128 in CBC mode and signed using a public key.

Those interested in learning more about the encryption and public keys can check out the related documentation via PSDevWiki.com. :geek:
Backup And Restore Keys (BAR)

*Cipher:
Code:
79 c8 cc c8 89 a1 54 0d 4f 2e 27 bb 61 4f d6 53
*Hasher:
Code:
cd a1 33 a1 0e c8 f5 25  98 22 23 f5 86 1f 02 00
And from the README.md: BAR

backup and restore decrypt (and encrypt?) utility

Credits
  • RedEye32 (for the structs)
  • Zer0xFF (for some improvement in code)
  • PixelButts (for testing)
  • idc (for the hasher key correct size)
  • and to anonymous (for everything you did and have done in the past)
Usage

compile it and simply place it near the archives and run it. it'll produce some blobs. support for bigger blobs is in process...
decrypt the backups made with the backup utility
very similar to what Kakaroto has done on ps3 with his tool
yes. on fpkg backups it'll also backup the licenses associated with them, because they are considered "free" licenses by the system
honestly, none besides grabbing the licenses from demo and beta games

I think backup decryption will not work unless we have decrypted pkgs. With PS3 it was for injecting decrypted pkgs to run on ofw.

@tk1278 due to the way the pkg's are encrypted and so many possible combos the passcode, you would need to start guessing prior to the universe existing (this is impossible)
