The PS4 content license files are like on PSP, PS3 and PSVita the .rif files.
But for the first time, the format has been changed a lot:
- There is only one .rif file (and .idx) per game/app. On PSP, PS3 and PSVita, there were 1 .rif per content (1 for the game + 1 for each DLC)
- This is handled by adding each DLC license to the game .rif. To know where the license is in the .rif, PS4 generates a .idx file (RIF index).
- When the .rif is downloaded from PSN by SceShellcore, it is added to the current .rif file of the game (if existing).
Then the .idx is generated. ShellCore calls npdrm_ioctl to get a 0x10 bytes HMAC-SHA256 per console key from SAMU.
The HMAC is computed over the RIF data and is written to the .idx entry.
The aim is both to ensure .rif integrity and to make sure the .rif and .idx can't be copied to another PS4 console.
The files an be found in:
- For disc licenses:
/mnt/disc/license/rif(on the BluRay) and/preinst2/app/CUSA00001/app.rif(on the HDD) - For digital content licenses:
/user/license/*.rif,/user/license/*.idx - For another type of digital content licenses:
/user/home/*/license/*.rif,/user/home/*/license/*.idx
RIF File[edit | edit source]
This is a .rif that is not paired with a .idx file.
For a rif file that is paired with a .idx file, see RIFA file.
The .rif file embeds one or more RIF entry.
RIF Entry[edit | edit source]
Fields are big-endian. Each RIF entry is 0x400 bytes sized.

RIFA File[edit | edit source]
This RIF form is paired with a .idx file.
When in this form, contrarly to RIF files a RIFA header is present, followed by sequential RIF entries.
See also IDX structure for the paired .idx file.
RIFA Header[edit | edit source]
Fields are big-endian. Size is 0x400 bytes.

IDX File[edit | edit source]
This is the RIF index file. It is used in pair with RIFA files.
RIF IDX[edit | edit source]
Fields are little-endian. Size is 0x20 bytes (header) + entries_count * 0x30 bytes (entry_size).
