What's the decryption for client recieve gamepacket? Just for the Numbers.
PM me.

I'm to lazy to make it by my self.

Decrypting server packets is easy
this is for auth encryption :

Code:

public class ServerCipher : CipherBase
    {

        override public int Decrypt(byte[] data, out byte[] buf)
        {
             if (!inGameEncryption)
            {
                buf = new byte[data.Length];
                for (int i = 0; i < data.Length; i++)
                    buf[i] = (byte)(data[i] - 0x0F);
                return data.Length;
            }

            int len = data.Length;
            int offset = 0;
            char[] table = { (char)0, ' ', '-', '.', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '\n' };

            ........


            return 0;
        }
      
    }

Auth Packets are not my problem :D
Just the recieve game packets. Bytes of Number Chars are fucked up.

But Thanks.

Code:

 char[] table = { (char)0, ' ', '-', '.', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '\n' };

should give you and idea on how to restore numbers.
it's more a string compression than an encryption

HEllo obscur,

i'm really interested...

Maybe it's not a true encryption, but a zlib stream compression?

Can you elaborate more on this please?
