Revision as of 05:17, 17 September 2022
Encrypted form of version.txt. Contains info about firmware version/build/date etc.
Location
PS3
/dev_flash/vsh/etc/index.dat
PS Vita
vs0:vsh/etc/index.dat
PS4
/priv/etc/index.dat
Decryption
Index.dat is aligned to 0x10 bytes, digested with SHA-1 (PS3), SHA-256 (PS Vita, PS4) then encrypted with AES128CBC (PS3), AES256CBC (PS Vita, PS4).
Reciprocally, index.dat is decrypted with AES128CBC (PS3), AES256CBC (PS Vita, PS4), digest is verified then version.txt is stored as null-terminated string and is displayed as is or parsed.

Correlation to PUP version
PUP Image version - versus Build number in index.dat/version.txt
PUP Image version is located at offset 0x10-0x17 example OFW 3.15 CEX:
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
00000000 53 43 45 55 46 00 00 00 00 00 00 00 00 00 00 01 SCEUF...........
00000010 00 00 00 00 00 00 94 8F 00 00 00 00 00 00 00 07 ......”.........
hex:948F (PUP image version) = dec:38031 (index.dat/version.txt)
On official firmwares the value is the same, but they are used in different stages. PUP image version is used by ps3swu.self (updater) when installing firmwares in normal and recovery mode. Index.dat/version.txt is not looked at when installing (hence, why you can have a 3.15 firmware with Image version correlating to 3.15 OFW and spoofed to look like a 4.11 firmware).
For MFW's/MFW Builder, the Image version is increased by +1, which is why you need to use Recovery mode to install a same version firmware.
