Table looks like xored

Ok. Here i written small tool for decrypting tables. Encryption is SWAP + XOR.

Edited: Done

[Ekey]

Job done.

Edited: See below.

[Ekey]

Encrypted files with extensions *.LUA , *.XET, *.TET *.FX.. Algo SEED in CBC mode + SWAP + XOR

Code: Select all

pSeed_Key1      dd 14999F34h, 317AD2ACh, 8652EA9Eh, 0D1B57149h
pSeed_Key2      dd 31DDAC84h, 29FF5489h, 0EE605CA3h, 1674FA07h

j_SEED_CBC_init(&ctx, 0, pSeed_Key1, pSeed_Key2);
j_SEED_CBC_Process((int)&ctx, pBuffer, 32, (int)pDstBuffer, (int)&dwSize);

Script xor keys

Code: Select all

set SCRIPT_KEY1 "0x826CCAB8"
set SCRIPT_KEY2 "0x46A2C7F2"
set SCRIPT_KEY3 "0x90DC3AFD"

Script updated. Supported decrypting LUA and ect. files. Some files can not be decompressed because windowBits -15. Use > offzip -z -15 -a. I temporary set unzip_dynamic and dunno how avoid it

Edited: See below.

WoW! Thank you so much!

Updated script again. Tidied script code, removed unused data and some changes

Updated for OBT version. Problem with decompressing some files from the memory is still there. I do not know what could be wrong. Use OffZip for example

Hi Ekey My friends, thank you for your great work, I downloaded the client, but cannot install, possibly Korea client upgrades, requires a new file.

hello, can you make repack tool too please ?

Updated script. Now support CMF from Indonesian client. Decrypting game scripts not supported anymore because they uses modified SEED algorithm (use COSTool and OffZip for now).

COSTool usage:

Code: Select all

COSTool <Source file> <Destination file>

Example

Code: Select all

COSTool "D:\Unpacked\STRING_TABLE_QUEST3_USA.LUA" "D:\Unpacked\STRING_TABLE_QUEST3_USA.LUA.dec"

After decrypt use OffZip for decompress.

Code: Select all

offzip -z -15 -a "D:\Unpacked\STRING_TABLE_QUEST3_USA.LUA.dec" "D:\Unpacked" 0

hello, can you make repack tool too please ?

Script not supports for reimport and repack files.

hey ekey, could you leech the new link to manually download game files ? the old ones dont work anymore (ex : DAT26000.CMF) i tried to decompile the client_code.lua but it didn't work with luac, the output file is 0kb
