L2 Decrypt for C2

Dear sirs,

As the new topic for the lineage II C2 Thailand, I found that the ini or txt file are
encrypted with new verison 411, did the L2decrypt tool will upgrade? or
you can tell me how to decrypt the file with 411 method, thank you very much.

This will Decrypt, but not Encrypt, but I hope it helps.

Thank you for the file, it will help even if it cannot encrypt.

Your Welcome, I am just wanting to further the Progress, just I dont know to much.

Thank you For The File :thumbup: :thumbup: :thumbup:

Yeah, it'll be nice once we're able to encrypt these new 411 files. One step closer to a C2 server I suppose.

All I ask is to share the Wealyh, lol. :thumbup:

Is anyone currently working on making a program to decrypt and encrypt the .ini files to 411? I really have no idea what would be involved in such a task...but I'm just wondering if anyone's trying to figure this new problem out.

thanks a lot.

useless until we get server =)

I have ask L2Decrypt author, Freakazoid, months ago (since KOR version starts to use v4.11 encryption), he answered, "Looks like packed(inflate) and rsa(2048bit) encrypted. As its asynchronous encryption it will be most likely only possible to decrypt but not re-encrypt."

So, you can decrypt v4.11 file(s) but can't encrypt it back because of RSA. It also has been confirmed by L2J's leading author, L2chef, too.

BTW, L2J releases "L2Proxy" to wrap C2 IP request to wherever you want.

client could be patched to avoid encryption at all, this will allow using unencrypted files
it's easy enough if you can decrypt everything... just patch all calls to encryption routine with nop (only where files get opened)
Is there some expirienced crackers to do that? I could try, but it would take much more time for me and i don't have C2.

Hi there my first post here, i'm not very experienced in client cracking but I have a "need-to-know" base and trying to figure out how to make the C2 Client read C1 encryption could be easyer like that :)

Assen

no its easier to force it to use unencrypted files

tried to use c2 files to connect by decrypting all files that were v411 no luck untill we can get hold of server files for c2 or someone who knows about this new encryption we will just have to sit back and wait or continue to play c1.....hope you didnt patch.......

if you decrypt everything you should also patch client to make it use unencrypted... it needs some debugging expirience

dammit someone hack ncsoft again lol. :chair: why am i so dumb :chair: or i would try :mail2: If i could speak any oriental languages i would try searching thru asian site surely there is a version of c2 there that someone has.

bad news guys.
the latest testserver client has already the new protection that ncsoft added to the korean client.
now the important executables are compressed, encrypted and have checksums.
additionally a background tool (Gameguard) is monitoring all the files (dunno about memory) and bitches about corrupt files if you change something. also the gameguard process has to run, otherwise the game client will complain.

looks like some tough stuff :(
