There are two kinds of SCE package files (.pkg):
= Firmware Packages =
* System Software Update Packages (.pkg), which are [[Certified File]]s containing patch files for some hardware or software components of the console,
* NPDRM Packages (.pkg), which can be either release or debug, that contain files for a specific game or application.


= System Software Update Packages =
== File Header ==  


System Software Update files are packed into .pkg files then encrypted into .spkg, a sort of [[Certified File]].
All values are in big endian format.


A System Update package contains 3 segments:
  typedef struct {
1) update_package_header
    u32 0x00, 0x53434500// magic
2) update_package_contents_header
    u32 0x04, 2 // version
3) update_package itself
    u16 0x08, 0 // sdk type?
 
    u16 0x0a, 3 // SCE header type; pkg
= NPDRM Packages =
    u32 0x0c, 0 // meta offset
 
    u64 0x10,          // size of sce_hdr + sizeof meta_hdr
== Security ==
    u64 0x18, 0x80      // + content_size_real
 
  }
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.

All game packages are signed with the ECDSA signature. The public key for it can be found in '''download_plugin.prx''' or in '''nas_plugin.prx''' (this also applies to NPDRM SELFs). Usually game packages are signed with two signatures - one for the header and the other for the entry table.

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 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];
}
}

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 ===
 
Official description: This is SHA1 digest of package without last 32 bytes.
 
The last 32 bytes of the package contain a hash (sha1sum) of the package (sha1 of the whole file minus the last 32 bytes). Or in other words... to verify the integrity of a package it 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 PackageDigest.
**PS3 homebrew packages (at least some of them) doesnt includes PackageDigest

=== Misc/Note ===

From FW 4.00, install PKG from root device (but not as "bubble") for PS1 classic if not containing [[EDAT_files|.EDAT files]] license type Free will abort or install directly as bubble according to the cfw.

== 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


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.
*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
