NetworkMessage Creating a new

[vincity]

In that code i have a exception.. my buffer always is 126 bytes long... so i have a diff of 2 between temp and usable area of buffer. Why i have that ? is a xteaKey Problem ? A protocol problem ? where is my mistake ?



Here information about how i try make that instance.

        //Rsa class
        public static bool RsaEncrypt(BigInteger e, BigInteger m, ref byte[] buffer, int position)
        {
 
            byte[] temp = new byte[128];
            try {
                Array.Copy(buffer, position, temp, 0, 128);
            }
            catch (Exception ex)
            {
                Console.WriteLine("temp["+temp.Length+"] buffer["+(buffer.Length-position)+"]");
                Console.WriteLine(ex.GetBaseException());
 
            }
            BigInteger input = new BigInteger(temp);
            BigInteger output = input.modPow(e, m);
            // it's sometimes possible for the results to be a byte short
            // and this can break some software so we 0x00 pad the result
            Array.Copy(GetPaddedValue(output), 0, buffer, position, 128);
 
     
            return true;
        }
 
        //NetworkMessage creator
 public static NetworkMessage Create(byte OS, ushort Version,
            byte[] Signatures, byte[] XteaKey, string AccountName, string Password, bool OpenTibia)
        {
            NetworkMessage msg = new NetworkMessage(149);
            msg.AddByte(0x95);
            msg.AddByte(0x00);
            msg.Position += 4;
            msg.AddByte(0x01);
            msg.AddUInt16(OS);
            msg.AddUInt16(Version);
            msg.AddBytes(Signatures);
            int offset = msg.Data.Length;
            int rsaStart = msg.Position;
            msg.AddByte(0x0);
            msg.AddBytes(XteaKey);
            msg.AddString(AccountName);
            msg.AddString(Password);
            int toAdd = 128 - (msg.Position - 6 - rsaStart);
            System.Console.WriteLine("offset " + offset + " rsaStart " + rsaStart + " " + toAdd);
            msg.RsaOTEncrypt(23);
            msg.AddAdler32();
            return msg;
        }
 
 
        byte[] xteaKey = new byte[16];
        rand.NextBytes(xteaKey);
        // Instancing a new NetworkMessage
        NetworkMessage networkMessage = LoginServerRequestPacket.Create(
            (byte)2,     // SO Version
            (ushort)860, // Tibia Version
            (new byte[12]{0x7A,0x60,0x3D,0x49,0x7C,0x4E,0x3D,0x49,0x78,0x41,0x14,0x49}), // Signature is Right ?
            xteaKey,    // key generate above
            "1",        //user
            "1",        //passwd
            true        // OpenTibia
            );

I really dont have any reference to that problem.
{ Remember that code dont use client it is not a possibility }

Try that.

NetworkMessage msg = new NetworkMessage(0x94);
msg.AddByte(0x94); // implementing msg.SetSize() instead of calculating by yourself would be better
msg.AddByte(0x00);
msg.Position += 4;
//msg.AddByte(0x01); ? 
msg.AddUInt16(OS);
msg.AddUInt16(Version);
msg.AddBytes(Signatures);
int offset = msg.Data.Length;
int rsaStart = msg.Position;
msg.AddByte(0x0);
msg.AddBytes(XteaKey);
msg.AddString(AccountName);
msg.AddString(Password);
int toAdd = 128 - (msg.Position - rsaStart);
System.Console.WriteLine("offset " + offset + " rsaStart " + rsaStart + " " + toAdd);
msg.RsaOTEncrypt(rsaStart);
msg.AddAdler32();

Hard to tell without rest of code, also this may help you

im using default clientless class from tibia api with some modifications in tibiaapi class ( for understand how in 8 60 login. )


I will post here.. ( that project is focused in debuging so have some ugly things )
