Editing PKG files

See also {{talk}} page, [http://www.psdevwiki.com/ps4/PKG_files PS4 PKG], [[PKG_DIGEST.DAT]], [https://psdevwiki.com/vita/index.php?title=System_File_Object_(SFO)_(PSF)].

There are two kinds of SCE package files (.pkg):
* System Software Update Packages (.pkg)
* NPDRM Packages (.pkg)

= System Software Update Packages =

System Software Update files are packed into .pkg files then encrypted into .spkg, a sort of [[Certified File]].

A System Update package contains 3 segments:
 1) update_package_header
 2) update_package_contents_header
 3) update_package itself

= NPDRM Packages =

== Security ==

The security of .pkg consists in some hashes and signatures.

All NPDRM packages are signed with an ECDSA signature. Usually NPDRM packages are signed with two signatures - one for the header and the other for the entry table.

PS3: file SHA-1 + QA digest + ECDSA signature.

PSP: PS3 securities + Extended Header (3 [[PKG_files#PKG_HMAC_algorithm|PKG HMAC]] hashes of the headers).

PS Vita: PSP securities + more Metadata (0xD-0x12) that embed digests of files embedded into the .pkg.

=== PKG Digest ===

See [[Keys#NPDRM_PKG.2FSELF_ECDSA_Public_Key]].

=== PKG HMAC algorithm ===

This is a 16 bytes hash using SHA-1 algorithm. Used in Extended Header hashes.

<source lang="C">
static void pkg_hmac(const uint8_t *data, unsigned int len, uint8_t hmac[16]) {
  SHA1_CTX ctx;
  uint8_t sha1[20];
  uint8_t buf[64];
  
  // Do SHA-1 of the actual data
  sha1_init(&ctx);
  sha1_update(&ctx, data, len);
  sha1_final(&ctx, sha1);
  
  // Setup the intermediate buffer
  memset(buf, 0, 64);
  memcpy(&buf[0], &sha1[4], 8);
  memcpy(&buf[8], &buf[0], 8);
  memcpy(&buf[16], &sha1[12], 4);
  buf[20] = sha1[16];
  buf[21] = sha1[1];
  buf[22] = sha1[2];
  buf[23] = sha1[3];
  memcpy(&buf[24], &buf[16], 8);

  // Do SHA-1 of the intermediate buffer
  sha1_init(&ctx);
  sha1_update(&ctx, buf, 64);
  sha1_final(&ctx, sha1);
  
  // Returns 16 first bytes from the 20 bytes SHA-1
  memcpy(hmac, sha1, 16);
}
</source>

=== Decryption ===

See also [[#Package_Tools]] and [[Keys#NPDRM PKG AES Keys]].

==== Finalized Packages ====

Finalized (retail) packages are encrypted using AES128CTR with a key derived from a constant key (NPDRM PKG AES key).

===== PS3 / PSP Finalized Packages =====

For PS3 / PSP NPDRM packages, the file table and the data are AES128CTR encrypted/decrypted using pkg_data_riv as the IV along with the PS3/PSP constant AES Key.

<source lang="C">
static void decrypt_finalized_npdrm_pkg(void) {
	u8 key[0x10];
	u8 iv[0x10];

	if (be16(pkg->pkg_type) != 1)
		fail("invalid pkg type: %x", be16(pkg + 0x06));

	if (key_get_simple("npdrm-pkg-key", key, 0x10) < 0)
		fail("failed to load the package key.");

	memcpy(iv, pkg->digest, 0x10);
	aes128ctr(key, iv, pkg + offset, size, pkg + offset);
}
</source>

===== PS Vita / PSM Finalized Packages =====

For PS Vita / PSM NPDRM packages type 2, 3 and 4, pkg_data_riv is AES128ECB encrypted with the constant per-platform AES128 key to create an AES session key. Then it does the normal AES128CTR with pkg_data_riv as the IV and the session key as the AES128CTR key.

<source lang="C">
// Source code to add here
</source>

==== Non Finalized Packages ====

Non Finalized packages use a key which is derived from the digest field of the package header, then used in a CBC like-mode which is then sha1'ed to get the final XOR key.

The derivation of the key differs between standard Non Finalized packages and arcade Non Finalized packages, e.g. [[Namco_System_357]].

<source lang="C">
static void decrypt_non_finalized_npdrm_pkg(void) {
	u8 key[0x40];
	u8 bfr[0x1c];
	u64 i;

	memset(key, 0, sizeof key);
	memcpy(key, pkg->pkg_header_digest, 8);
	memcpy(key + 0x08, pkg->pkg_header_digest, 8);
	if (isArcade)
		memcpy(key + 0x10, pkg->pkg_header_digest, 8);
	else
		memcpy(key + 0x10, pkg->pkg_header_digest + 0x08, 8);
	memcpy(key + 0x18, pkg->pkg_header_digest + 0x08, 8);
	if (isArcade)
		memset(key + 0x20, 0xA0, 0x18);

	sha1(key, sizeof key, bfr);

	for (i = 0; i < size; i++) {
		if (i != 0 && (i % 16) == 0) {
			wbe64(key + 0x38, be64(key + 0x38) + 1);	
			sha1(key, sizeof key, bfr);
		}
		pkg[offset + i] ^= bfr[i & 0xf];
	}
}

== File Header ==

Header consists of main header that points to metadata header. PSP and PS Vita .pkg also have .ext header right after main header.

== File Footer ==

=== PackageDigest ===

This is SHA1 digest of package without last 32 bytes.

The last 0x20 bytes of the package contains a hash (sha1sum) of the package (sha1 of the whole file minus the last 0x20 bytes). Or in other words... to verify the integrity of a package is needed to crop the 0x20 bytes at the end, then calculate the SHA1 of the resulting file, then compare with the SHA1 that was cropped.

It is also used as part of the package identification info inside the '''TITLE_ID-ver.xml''' files in PSN servers that lists the available game patches for each game. See: [[Online_Connections#Game_Updating_Procedure|Game Updating Procedure]] page and the '''sha1sum''' in the .xml examples

*Notes
**This footer area is considered part of the package and is included when counting the '''total_size''' of the package (in the header at offset 0x18), and the header is hashed too by '''header_sha1_hash ''' (at offset 0xB8), this is important in the sequence of actions needed when building the package and updating/adding the sha1 footer at the end
**Homebrew packages (at least some of them) doesnt includes this footer

Game Manual Protection
To use NPDRM to protect the game manual, include the line "ProtectDocument = TRUE" in
the configuration file. Like the downloadable game itself, once protected, the relevant game
manual can only be browsed on a PSP™ that was authenticated with the user account used
to purchase the downloadable game package. If "ProtectDocument = FALSE" is specified or
if no specification is made, the game manual will not be protected by NPDRM.

You can specify that a startup warning be displayed when the game is started up. Specify

indicates the region or language where the downloadable game package will be released.
See Chapter 7 for the corresponding text that is displayed.

| ZIPThreshold || used in PSP Downloadable Game Package (PSP .pkg)
Compression Rate Specification
During authoring of a downloadable game package, the data in the associated UMD™
image file is compressed. You can change the compression rate by specifying
"ZIPThreshold=" followed by the compression rate (0 to 100). If there is no "ZIPThreshold="
specification, the compression rate will default to 80. If "ZIPThreshold=0" is specified, the
data will not be compressed and there will no longer be any load for expanding the
compressed data. However, the file size will increase and it will take longer for the user to
download the package. Unless you specifically need to change the compression rate, do not
include this specification.

| OptimizeLevel || used in PSP Downloadable Game Package (PSP .pkg)
The SCE authoring service may change the optimization level to improve processing
performance when the system reads data in a downloadable game. If this change hinders
the behavior of a program that is being developed, you can include the specification
"OptimizeLevel=" followed by the optimization level that was used previously during
authoring. If there is no impediment to program behavior, you should not enter this
specification.
When the authoring service changes, refer to details that are publically available in the
Technical Notes.

| BootablePlatformDetails || used in PSP minis Package (PSP minis .pkg)
Game applications created via the Simple Authoring Service(SAS) having the above parameter
specified can be executed on PlayStation®3. When it is required to prohibit a minis game
application from running on the PlayStation®3 execution environment explicitly, set
"BootablePlatformDetails=onlyPSP" to NPDRM.CONF in addition to the setting
"BootablePlatform = minis".

At some point, SCE renamed make_package_npdrm to make_pkg. The reason is certainly that on PS Vita, .pkg are used for many types of contents not just NPDRM protected contents.

==== Make Package Npdrm Patcher (revision 1732) by SubZero Dezigns (2012) ====

A tool that patches official make_package_npdrm.exe (revision 1732) in order to remove its protections to build packages that embeds NPDRM already encrypted SELFs.

==== Make Edata/Package NPDRM GUI by SubZero Dezigns (2012) ====

A GUI program for Windows that patches on-the-fly official make_package_npdrm.exe (revision 1732) and allows to configure package.conf.

==== Force Package NPDRM by DEL1GHT Team (2010) ====

FORCE_PACKAGE_NPDRM is a modded version of SONY's "MAKE_PACKAGE_NPDRM".

It enables the repackaging of DRM'ed games into a .PKG file.

Howto :

First create the following structure :

	* PARAM.SFO

	* ICON0.PNG

	* ...

	* TROPDIR

	* USRDIR

		* Original EBOOT.BIN renamed to whatever you want (ie. GAME.BIN)

		* YOUR EBOOT.BIN (SELF file)

		* ...
	
Your EBOOT.BIN must launch the original EBOOT.BIN (ie. GAME.BIN)
	
Usage : force_package_npdrm [options] config-file target-directory

	11/08/10 - V1.00 - Initial Release

		- Based on SONY's "MAKE_PACKAGE_NPDRM Rev. 1203"

		- "Extended" help with "--help" option

		- Packaging of your SELF EBOOT.BIN

		- Repackaging of SELF/SPRX/EDATA DRM'ed files 
		
	11/11/10 - V1.50 - Updates

		- Based on SONY's "MAKE_PACKAGE_NPDRM Rev. 1732"

		- Repackaging of SDATA DRM'ed files

		- Repackaging of TROPHY directory

==== PSN Package NPDRM by DEL1GHT Team (2010) ====

PSN_PACKAGE_NPDRM is a fork of FORCE_PACKAGE_NPDRM.

It rebuilds PSN DRM'ed games into a .PKG file.

Original DRM'ed EBOOT.BIN is packaged as "raw data" ;-)

Still the problem of licence (act.dat) to run the game on another PS3.
	
Howto :

Download the PSN game directory from your HDD0 to your PC.

Create a "config-file" (a lot of explanations on internet).
	
Usage : psn_package_npdrm [options] config-file target-directory

	11/11/10 - V1.00 - Initial Release

		- Based (fork) on FORCE_PACKAGE_NPDRM V1.50

		- Full repackaging of PSN games
