0x0008 0x8 unknown
0x0010 0xC0 static keys decrypted with sceSblAuthMgrGetEKcForDriver key 0.

First 0x10 bytes are reencrypted with ConsoleId.

First 0x10 bytes are aes_key used to decrypt 0x800 bytes of Primary Key Table from act.dat.

Second 0x10 bytes are aes_key used to decrypt Primary Key Table index from rif.

This data is compared against OpenPsId from act.dat.

This key is compared against OpenPsId in from .rif file at offset 0xC0.

Obtaining klicensee

1. Get the list of static keys. (on 3.60, 0xC0 bytes from SceNpDrm code segment at offset 0x111D0)

2. Decrypt 0xC0 bytes of static keys using sceSblAuthMgrGetEKcForDriver key 0.

3. Get 0x10 bytes of ConsoleId using sceSblSsMgrGetConsoleIdForDriver.

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

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

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).

Scenario 1

Take RIF Key 2.

Take static keys 3, 4.

Take first 0x70 bytes of RIF data.

Use 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 data.

Use sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 2 and obtain klicensee.

Scenario 3

Take RIF Key 2.

Take cmd56 handshake keys with get_5018_data.

Take first 0x70 bytes of RIF data.

Use sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 2 and obtain klicensee.

Scenario 4 - maybe Cartridge

Take RIF Key 1.

Take cmd56 handshake keys with get_5018_data.

Take first 0x70 bytes of RIF data.

Erase RIF Key 1 from RIF data.

Use sceSblAuthMgrDecBindDataForDriver to decrypt RIF key 1 and obtain klicensee.

Scenario 5 - maybe DRM Free

Decrypt Primary Table Key index from RIF data 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).

Get rif name

};

int aes_encrypt(const void *buf, int size, uint8_t *keys) {
	AES_ctx ctx;
	AES_set_key(&ctx, rif_name_keys, 0x80);

	int i;
	for (i = 0; i < size; i += 0x10) {
		AES_encrypt(&ctx, buf+i, buf+i);
	}
}

typedef struct {
	uint64_t mode; // 0: bounded, 1: fixed
	uint64_t aid;
} SceNpDrmRifName;

int getRifName(char *name, int length, uint64_t aid, uint64_t mode) {
	SceNpDrmRifName rif_name;
	rif_name.mode = mode;
	rif_name.aid = aid;
	aes_encrypt(&rif_name, sizeof(SceNpDrmRifName), rif_name_keys);
	
	snprintf(name, length, "%016llx%016llx.rif", __builtin_bswap64(((uint64_t *)&rif_name)[0]), __builtin_bswap64(((uint64_t *)&rif_name)[1]));

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 1.60 it's 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 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 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.
