Unpack DataCenter from newest Gameforge EU Client

[coolyt]

Hey :)

is there any actual tool around that could decrypt and unpack the DataCenter from the latest Tera EU Client ?
i tried with TDCDec, it hasn't worked ..
or does anyone know HOW it's encrypted ?
as i can remember on old Client DataCenterFiles the Encryption was AES-128-CFB but looks like this doesn't work on the newer files ..

If anyone could help, plz do it :P

Thanks in advance :)

I asked myself the same question a few days ago. I found out the same, there is a old Decrypt Tool but it is only working with that old client versions. The AES Key is changed at every update. (http://forum.xentax.com/viewtopic.php?f=10&t=8426).

Unless you are able to unpack and find the actual key there is no chance to get the files.
I tried to get the Key from the actual Client, but I failed already on the unpacking of the client part :D
Maybe someone who is more skilled at this should look at it.

Still no chance to get into the DataCenter file ? i need the xmls for a emulator project ..
i'm reworking the angelis version of the jenova core updating it to actual client and develop the missing functions. this is a lot of work .. and if there is no chance to get the new static datas out from the client it doesn't make sense to put in a lot of hours for nothing ..

so if anyone sees a chance to get the new or any nearly new datacenterfiles decode plz help me :)

thnx in Advance

are you making any effort yourself?
yes its AES 128 CFB, however the key and iv change every patch, and therefore the old decryptor will not work.
if the info is so important to your emulator maybe you should hire someone to help you if you cannot do it yourself.

currently taking a look at it myself, unpacked and found the aes routines, need to find the key+iv though

edit:
i think i got it, need to parse the uncompressed data into xml files though

edit2:
if anyone was curious, decrypting and decompressing the datacenter file is not enough, none of the tools here work for the new versions. the data tools suite that was released is entirely hardcoded - i updated it the best i could but theres a lot of magic numbers in there that i dont know where came from. atm, its not looking good.

uuh you done it ? Pretty cool :) -> u got private msg :)
no i did not made any effort with the datacenter thing .. :(
but a few steps with my emu :) actually it's possible to run around kill mobs and make a few quests with actual GF client :) actually i'm inspecting and adapting the new packets :)

i already have over 90% of the packets finished. i'm working on an emulator myself, although mines built from scratch and closed source.

quest logic is mostly finished, combat logic is working but without the full info from the data center i cant get all the mobs working right nor drop tables. i have item info but not completely. item stats and such im lacking, ids/classes/level restrictions i have. pretty much everything is done except setting up some databases and a bit of backend logic for spawning mobs/dropping loot lol.
