[HELP] - De/Encoding packets

04/09/2016 15:31 lika85#1

Hi, i am trying clientless bot for nostale in C#, and i have problem with encoding and decoding packets, can anyone give me some functions? (de/encode login packet, de/encode game packet, encode password ). I was searching these functions and i found only some old funcs and funcs in c++ wich is like if u hit keyboard. Login in PHP is working for me, but if i send another packet, no response come to me. This is my code:

Code:

        public TcpClient client = new TcpClient();
        public string tempString = "";
        public NetworkStream stream;
        const string HASH = "529D12EF5699E29548A9914C7B2AB6DFA735FA8053A6B0EDFF75E607FF3EBBED";
        private string id="somethink";
        private string password="somethink";



        private void buttonLogin_Click(object sender, EventArgs e)
        {
            try 
            {
                client.Connect("79.110.84.75", 4006);
                stream = client.GetStream();
                print("Connected to server!");
            }
            catch (SocketException err)
            {
                print("Cannot connect to server! Error: "+err.ToString());
            }

            id = labelNickname.Text;
            password = labelPassword.Text;
            password = PASSWORD_ENCODING_FUNC(password); - This isnt working i know
            string loginMessage = "NoS0575 597064 " + id + " " + password + " 008B8CF9";
            loginMessage +=((char)11).ToString();
            loginMessage +="0.9.3.3055 0 "+md5(hash+id).ToUpper();
            loginMessage= LOGIN_PACKET_ENCODING_FUNC(loginMessage);
            client.Write(loginMessage,0,loginMessage.Length);

1- Its Encryption, not Encoding < no! not the same thing!! >

2- You have here all functions you need in C++
( nobody will convert it for you, stop be lazy and start doing things by yourself )

Please guys, have anyone encryption and decryption functions in C#? I am trying to translate it from php and c++ and its still not working..

Spoiler

Code:

        public string packet_enc(string packet)
        {
            byte[] ret = new byte[packet.Length];
            for (int i = 0; i < packet.Length; i++) { ret[i] = (byte)((int)packet[i] + 15); }
            return ByteArrayToString(ret);
        }
        public string packet_dec(byte[] packet, int bytes)
        {
            string dec = string.Empty;
            char[] chars = new char[bytes];
            int test = 0;
            for (int i = 0; i < bytes; i++)
            {
                chars[(int)i] = (char)(packet[(int)i]);
                test = (((int)chars[i] - 15) ^ 195);
                if (test < 0) test = (test % 256) + 256;
                dec += (char)test;

            }

            return dec;
        }
        public string password_enc(string password)
        {
            Random rnd = new Random();
            string str_hex=ToHex(password).ToUpper();
            int pos = rnd.Next(0, 22);
            pos = 3;
            byte[] secondtable = { 0x2E, 0x2A, 0x17, 0x4F, 0x20, 0x24, 0x47, 0x11, 0x5B, 0x37, 0x53,
                                          0x43, 0x15, 0x34, 0x45, 0x25, 0x4B, 0x1D, 0x2F, 0x58, 0x2B, 0x32, 0x63 };
            string pw_enc = ToHex(((char)secondtable[pos]).ToString()).ToUpper();

            for (int i = 0; i < str_hex.Length;i+=2 )
            {
            pw_enc += ToHex(((byte)((secondtable[pos] + 240) / 4)).ToString()).ToUpper();
			pw_enc += str_hex[i];
			pw_enc += ToHex(((byte)(secondtable[pos] + 15)).ToString()).ToUpper();
			pw_enc += str_hex[i + 1];
            
                return pw_enc;
        }
        public string md5( string input)
        {
            MD5 md5Hash = MD5.Create();
            byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));
            StringBuilder sBuilder = new StringBuilder();
            for (int i = 0; i < data.Length; i++)
            {
                sBuilder.Append(data[i].ToString("x2"));
            }
            return sBuilder.ToString();
        }
