1. Get the list of static keys. (on 3.60, 0xC0 bytes from SceNpDrm code segment at offset 0x111D0)
Initialization steps (common):
 
1. Get the hardcoded encrypted EKc (0xC0 bytes). (on FW 3.60, 0xC0 bytes from SceNpDrm code segment at offset 0x111D0)
 
2. Decrypt the hardcoded encrypted EKc using [[SceSblAuthMgr#sceSblAuthMgrGetEKcForDriver|sceSblAuthMgrGetEKcForDriver]] with key revision 0 (?or 1 or 2?).


2. Decrypt 0xC0 bytes of static keys using [[SceSblAuthMgr#sceSblAuthMgrGetEKcForDriver|sceSblAuthMgrGetEKcForDriver]] key 0.
Initialization steps (per-console):


3. Get 0x10 bytes of ConsoleId using [[SceSblSsMgr#sceSblSsMgrGetConsoleIdForDriver| sceSblSsMgrGetConsoleIdForDriver]].
3. Get ConsoleId (0x10 bytes) using [[SceSblSsMgr#sceSblAimgrGetConsoleIdForDriver|sceSblAimgrGetConsoleIdForDriver]].


4. Encrypt first 0x10 bytes of static keys with ConsoleId using AES (need to figure out which AES exactly).
4. Decrypt using AES128ECB first 0x10 bytes of EKc with ConsoleId as key.


5. Read 0x800 bytes of Primary Key Table from act.dat
5. Read 0x800 bytes of the encrypted Primary Key Table from act.dat file.

6. Decrypt 0x800 bytes of Primary Key Table with reencrypted static key using AES (need to figure out which AES exactly).


7. Get 0x97 / 0x200 bytes of RIF data and select one of 5 scenarios for decrypting RIF Key based on license flags (need to figure out).
Initialization steps (per-content):
 
7. Get 0x98 / 0x200 bytes of RIF from the content's .rif file and select one of the 5 scenarios for decrypting RIF Key into klicensee based on DRM Type (need to figure out). In most cases, only the first 0x70 bytes are needed for klicensee derivation because at 0x70 is the ECDSA signature which is not used for derivation, and after 0x98 are data only used for some PS Vita contents (maybe only PS Vita gamecards require a 0x200-byte RIF).

The rif file holds the klicensee for NPDRM contents.
The RIF file holds the klicensee for NPDRM contents. The RIF files are used as DRM licenses. For each installed PKG and Game Card you have a unique RIF file with proper information that is used when you open the game to verify if you own the game (or PKG). The RIF files holds important information as PSN Account ID, the key used to decrypt one of the SELF encryption layers.


The RIF files are used as the eboot.bin DRM. For each installed PKG and Game Card you will have an unique RIF file with proper information that will be used when you open the game to verify if you own the game(to PKG) and decrypt the eboot.bin. The RIF files may hold important information as PSN Account ID, the key used to decrypt one of the SELF encrypt layers [...].
PS Vita supports two different RIF file formats. The first format version (v0) is used by RIF files with 0x98 bytes size and the second version (v1) is used by RIF files with 0x200 bytes size. The difference between these formats is just the signature and some data used by PS Vita only. RIF version 0 only uses ECDSA Signature only whilst RIF Version 1 uses the ECDSA Signature and an extra RSA Signature.
 
PSVita supports two different RIF file format. The first format (License Type 0) seems to be used by licenses with 0x98 bytes size and the second (License Type 1) seems to be used by RIF files with 0x200 bytes size. The difference between them is just the signature verification. License Type 0 only uses ECDSA Signature, the License Type 1 uses the ECDSA Signature verification and an extra RSA signature verification.

Obtaining klicensee

Initialization steps (common):

1. Get the hardcoded encrypted EKc (0xC0 bytes). (on FW 3.60, 0xC0 bytes from SceNpDrm code segment at offset 0x111D0)

2. Decrypt the hardcoded encrypted EKc using sceSblAuthMgrGetEKcForDriver with key revision 0 (?or 1 or 2?).

Initialization steps (per-console):

3. Get ConsoleId (0x10 bytes) using sceSblAimgrGetConsoleIdForDriver.

4. Decrypt using AES128ECB first 0x10 bytes of EKc with ConsoleId as key.

5. Read 0x800 bytes of the encrypted Primary Key Table from act.dat file.

6. Decrypt 0x800 bytes of Primary Key Table with reencrypted static key using AES (need to figure out which AES exactly).

Initialization steps (per-content):

7. Get 0x98 / 0x200 bytes of RIF from the content's .rif file and select one of the 5 scenarios for decrypting RIF Key into klicensee based on DRM Type (need to figure out). In most cases, only the first 0x70 bytes are needed for klicensee derivation because at 0x70 is the ECDSA signature which is not used for derivation, and after 0x98 are data only used for some PS Vita contents (maybe only PS Vita gamecards require a 0x200-byte RIF).

Scenario 1 - maybe DRM Free

Take RIF Key 2.

Take static keys 3, 4.

Take first 0x70 bytes of RIF.

Use SceSblAuthMgr#sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 2 and obtain klicensee.

Scenario 2

Take RIF Key 2.

Take primary keys 1, 2.

Take first 0x70 bytes of RIF.

Use SceSblAuthMgr#sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 2 and obtain klicensee.

Scenario 3 - Game Cartridge

Take RIF Key 2.

Take cmd56 handshake keys with get_5018_data.

Take first 0x70 bytes of RIF.

Use SceSblAuthMgr#sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 2 and obtain klicensee.

Scenario 4 - Game Cartridge

Take RIF Key 1.

Take cmd56 handshake keys with get_5018_data.

Take first 0x70 bytes of RIF.

Erase RIF Key 1 from RIF.

Use SceSblAuthMgr#sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 1 and obtain klicensee.

Scenario 5

Take RIF Key 1.

Decrypt Primary Table Key index from RIF with static key 2 using AES (need to figure out which AES exactly).

Take primary key using decrypted index.

Decrypt RIF key 1 with obtained primary key using AES (need to figure out which AES exactly).

Package integrity checks

Disable hash/signature verification

To find the function responsible for package verification search for immediate 0x7F504B47 ('.PKG'). Inside it does a lot of stuff including determining the function that will do signature checks. Find the condition that looks like if ( (v62 & 7) == 3 ); below you will see the assignment check_func = &off_81009CFC;. To bypass signature checks you need to patch two functions located at this offset and offset+4, making them behave as "return 1" is enough. For reference, on 1.60 the functions are sub_81000310 and sub_81000AA4. sub_81000310 is the only function in this module that calls SceSblGcAuthMgrPkgForDriver_E459A9A8_imp.

Note that on 1.60 this module sometimes is loaded at different addresses between reboots.

Allow debug packages to be installed

Find the function that calls sceSblAIMgrIsCEXForDriver. Patch it to always return 1. On FW 1.60 it is at 0x81002d64.

Search for immediate 0x80870003, there should be two matches. Replace both with "MOV Reg, #0". On 1.60 the locations are 0x810035fe and 0x81004856.

RIF

The RIF file holds the klicensee for NPDRM contents. The RIF files are used as DRM licenses. For each installed PKG and Game Card you have a unique RIF file with proper information that is used when you open the game to verify if you own the game (or PKG). The RIF files holds important information as PSN Account ID, the key used to decrypt one of the SELF encryption layers.

PS Vita supports two different RIF file formats. The first format version (v0) is used by RIF files with 0x98 bytes size and the second version (v1) is used by RIF files with 0x200 bytes size. The difference between these formats is just the signature and some data used by PS Vita only. RIF version 0 only uses ECDSA Signature only whilst RIF Version 1 uses the ECDSA Signature and an extra RSA Signature.
