PS4 HDD Script by anonymous

I doubt those keys are ever copied to RAM (@zecoxao ?). But there are several data security for RAM like ASLR implementations, even Dreamcast have one which was pain the ass for cheat devices (if I'm correct, I believe @bucanero or @atreyu187 know far more about this platform). Some contents can be additionally encrypted, encoded, obfuscated in any way. It is not just easy as frozen RAM and dump it outside and drowning into Alibaba's cave.

AES XTS is wildly use today. Fast, lightweight and so far secure.

How to handle PFS we don't really know (maybe except Flatz), even Apollo not messing with them but "asking" PS4 to do it.

yes, for example, on both Apollo Vita and Apollo PS4, the encryption is handled by the system and we are just "asking" the underlying system to open (mount) the pfs for us. (Some patches are applied in memory so the system accept our "requests", but as said, the decryption and encryption is done by the system)
