Editing Content License

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).<br />Then the .idx is generated. ShellCore calls npdrm_ioctl to get a 0x10 bytes HMAC-SHA256 per console key from SAMU.<br />The HMAC is computed over the RIF data and is written to the .idx entry.<br />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: <code>/mnt/disc/license/rif</code> (on the BluRay) and <code>/preinst2/app/CUSA00001/app.rif</code> (on the HDD)
* For digital content licenses: <code>/user/license/*.rif</code>, <code>/user/license/*.idx</code>
* For another type of digital content licenses: <code>/user/home/*/license/*.rif</code>, <code>/user/home/*/license/*.idx</code>

== RIF File ==

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|RIFA file]].

The .rif file embeds one or more [[RIF Entry|RIF entry]].

[[Rif/samples|Sample disc rif files]].

=== RIF Entry ===

Fields are big-endian. Each RIF entry is 0x400 bytes sized.

== RIFA File ==

This RIF form is paired with a .idx file.

When in this form, contrarly to [[#RIF File|RIF files]] a [[#RIFA Header|RIFA header]] is present, followed by sequential [[#RIF Entry|RIF entries]].

See also [[#RIF IDX|IDX structure]] for the paired .idx file.
