Extraction

The PS VITA update files can be extracted using the "PS VITA Firmware xTractor" or the pupunpack from vitatools.

Decryption

To decrypt the files which are unpacked using the tool, the key is available under PS Vita Keys

Structure

The file structure of the Vita's PUP files is almost identical to the PS3's, although there is a slight difference in the header and the hash algorithm. For starters, whereas in PS3 the format was big-endian for the Vita it has been switched to little-endian (probably the same for all Vita formats). Also the Package Version field in Vita pups is set to 2 where in PS3 updates it was set to 1. There is also 0x50 bytes of extra data in the header and the hashes used are of a longer length than in PS3 updates (0x20 bytes in Vita vs 0x14 in PS3)

Header

Offset	Length	Type	Information
0x0	0x8	unsigned long	Magic (hex: 0x5343455546000001 ~ ASCII "SCEUF")
0x8	0x8	unsigned long	Package Version
0x10	0x8	unsigned long	Image Version
0x18	0x8	unsigned long	File Count
0x20	0x8	unsigned long	Header Length (2048, file data starts from here)
0x28	0x8	unsigned long	Package Length (size of PUP file - 8)
0x30	0x50	UNKNOWN	UNKNOWN, same for all >V1.0 files so far, maybe something for extra security? (or maybe to break a PS3 which tries to read the update) Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00000030 02 00 00 00 01 00 00 00 00 00 00 00 02 00 00 00 ................ 00000040 00 00 00 00 0F 00 00 00 00 00 00 00 00 00 00 00 ................ 00000050 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000060 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

0x80 + (0x20 * File Count)	0x40 * File Count	Hash Table	Hash Table
0x80 + (0x60 * File Count)	0x20	bytes	Header Hash (unknown algo?)

File Table

The file table consists of a number of file entries determined by File Count, with the format below (which is the same as the format in PS3 PUP1 files)

Offset	Length	Type	Information
0x0	0x8	unsigned long	Entry ID
0x8	0x8	unsigned long	Data Offset
0x10	0x8	unsigned long	Data Length
0x18	0x8	unsigned long	Unknown

Filename IDs

0x400	package_scewm.wm
0x401	package_sceas.as

Hash Table

The hash table contains a hash entry for every file inside the PUP.

The hash entry format is:

Offset	Length	Type	Information
0x0	0x8	unsigned long	File Index
0x8	0x20	bytes	File Hash (hmac-sha256 algo?)
0x28	0x18	bytes	Unknown

Regioning

If simular to PS3, then there is no regioning in the .PUP files, they are the same for all different regions.
The PS Vita however gets the psp2-updatelist.xml from different servers, depening on the region of that model.
