- Unlike the ps3, where every part of perconsole security (including the HDD) is dictated by the eid_root_key, the ps4 has two perconsole keys for the HDD, one is handled by SAMU (we cannot obtain this key atm) and the other is handled by the South Bridge / AEOLIA / BELIZE (which we can obtain)
- Here I describe the steps to mount your hdd on the pc using the cryptmount utility on Linux
Setup
- EAP HDD Key (check in your kernel dump and in hxxps://github.com/Ps3itaTeam/ps4-kexec/blob/master/magic.h kern_off_eap_hdd_key offset)
- Linux Distro (i'm using xubuntu live for this)
- cmtab file
Step by Step Guide
- cmtab file can be as follows (example for xubuntu live)
# /etc/cryptmount/cmtab - encrypted filesystem information for cryptmount
# try 'man 8 cryptmount' or 'man 5 cmtab' for more details
user {
dev=/dev/sda27
dir=/home/xubuntu/Desktop/user
flags=user,nofsck
fstype=ufs mountoptions=ro,noatime,noexec,ufstype=ufs2
cipher=aes-xts-plain64
keyfile=/home/xubuntu/Desktop/eap.bin
keyformat=raw
}
- if your key in the kernel dump looks like this:
D2 60 86 B3 8B D2 D3 5A EC 76 DB DE 50 30 00 40 15 D6 AE 04 44 3D A8 59 4B 03 3C 1F 0A DD FA 6B
- then the correct key will be:
40 00 30 50 DE DB 76 EC 5A D3 D2 8B B3 86 60 D2 6B FA DD 0A 1F 3C 03 4B 59 A8 3D 44 04 AE D6 15
