AuthServer De/En ?

First of all i wanna say hello to every1.

And after reading lots of information about conquer cryptograpgy cant figure out what exactly encryption/decryption loginserver use?
Somethig similar to XOR encryption ? what exactly?
If i dont know that exactly it is then i cant write my proxy.

I`ve read pro4ever thread but there is only explanation how proxys works and almost zero about how to create it (i dont need that some1 give me full code of proxy).

You could use AuthProtocolCryptographer class wich is avaliable in c# and vb.net (see my thread 'porting authprotocolcryptographer to vb')

I guess this class can handle the whole Authentication phase, then I GUESS all the other packets uses blowfish and theres a c# wrapper for it. I'm still stuck on authentication.

oh thanks almost everything works just now i cant firure out why auth response packets decryting are wrong. But others packets recrypting fine except auth response. Any offer/soliution ?

if you are writting in C# and you're using the C# authcryptographer codes available in this forum properly, you will not get a decryption/encryption error. If you're not writing in C#, make sure you do something about the byte type. seems that byte in C# is by default unsigned ...

byte is unsigned in C#, sbyte is signed in C#
