Well this part not needed because it's only for 1b87c6b551e518d11114ee21b7645a47.pkg get wVersion short get bEncryption byte get bFlag byte get dwDataSize long In other PKGs with datas > Header is 32 bytes - just md5 hash null terminated string of full file. PS: and yes my bad > password 1 -> kbuj37...

Okay, what's next!..... We need generate key and iv for decrypt PKG data's. How it work: 1 ) Get any PKG 2 ) Get name from full path 3 ) Set Password 1 4 ) Calculate MD5 hash for Password 1 5 ) Set Password 2 6 ) Calculate MD5 hash for Password 2 7 ) Convert Password 1 Hash to string 8 ) Convert Pas...

Well 1b87c6b551e518d11114ee21b7645a47.pkg - Encrypted main file contained list of avaible PKGs. Structure only for this file: struct PKGHeader { WORD dwVersion; // 0x01 0x00 BYTE bEncryption; // ID of encrypt algorithm ( 1 - AES-128-CBC , 0 - BlowFish-CBC ) BYTE bFlag; // 6 DWORD dwDataSize; }; Key ...

It's W.I.P -> Work in Progress!

Thanks I figured out

Code: Select all

unsigned int pT1[] = { 0, 0, 0, 0 };
unsigned int pT2[] = { 0, 0, 0, 0 };
static unsigned int *pTransparent[2] = { *pT1, *pT2, };

It works!

Ekey

I'm rly bad know Sharp but maybe someone can explain what this?

Code: Select all

private uint[][] pTransparent;

It's something like this ?

Code: Select all

DWORD ** pTransparent

or

Code: Select all

DWORD ** pTransparent []

?

Ekey

Seems encrypted

Edited: just xored zip

Code: Select all

filexor "\x29\x61\x53\x33"
get SIZE asize
log "decrypted_file.dat" 0 SIZE

Ekey

Well seems it's modified variant of default ZIP format.

Decryption key: here also changed keys for xxtea. Anyway tool for decrypt and convert NPK and PAK to ZIP in attach. This is modified part of tool for decrypt PAKs from Crysis 3 by Sir Kane Usage PakDecrypt <input npk/pak> [output zip] Tested on Icarus Online [KR] [L] (2014) [1.1.4] Enjoy :P
