Metin 2 server Developement

[luffydu22]

Hi everyone, i work for a Metin2 Multi-threaded server developpement (in a one time i hope to implant a multi realm support for the PVP and PVE playing)

but for the moment i'm blocked because the auth packet that i've sniffed was crypted.

anyone know how the client encrypting the network packet ?

thanks for all.

see you soon

Hello,
so when you don't know something about the packet decryption of metin2, than i have an good tip.

You don't know what problems you get while the development.

With your little knowledge about that, let it.

It's really hard work to finish the game core.

Try first an clientless bot program.

Thanks for you reply.
I've already developped a server core, for WoW, I was work in many private server for example the most popular french server "Millenium", for my personnal experience, i've reversed some crypting algorithm, decompileted with IDA+HExRay(and some other tools)...

but for Metin2 I don't have some idea on the encryption used for this Network packet.
Can you tell me some tips about this network protocol ? =)

the packet algorythm is called TEA, it's the same used for the eix/epk files. the key used for packets is the "pong" key (testtesttesttest,123abcd4567efgh, etc...) hope this helps.

Could it also be that Metin2 uses some other algorithm like xTEA or xxTEA?
I can't try now but I will do some tests on some packets later today...
