Nostale packet to official server problem

[SlayZ85]

Hello,
I am trying to make an C# application that will verify if your nostale login informations are good.
In PHP, I sent the packet "NoS0575 6322112 USERNAME 109177246F927042641467C191156B736755635463B1358334 5 00332B980.9.3.3055 0 B5D5C01C083E1F954259316FE2206F9D", and it returned me the list of the channels, so it works in PHP.
But then I tried with C#, and it respond me "fail An error occured .. Try again" but I have the same socket connection as php and good cryptography (I think)

Here is my C# connection :

 string packet = "NoS0575 6322112 USERNAME 109177246F927042641467C191156B736755635463B13583345 00332B980.9.3.3055 0 B5D5C01C083E1F954259316FE2206F9D";
            byte[] bytesToSend = Cryptography.EncryptLogin(packet);
            Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, 0);
 s.Connect(SERVER_IP, PORT_NO);
            byte[] bytes = new byte[bytesToSend.Length];
            s.Send(bytesToSend, bytesToSend.Length, SocketFlags.None);
            
            s.Receive(bytes, bytesToSend.Length, SocketFlags.None);
            string decrypted = Cryptography.DecryptLogin(bytes, bytesToSend.Length);
            Console.WriteLine(decrypted);

And my cryptography:

public static string DecryptLogin(byte[] bytes, int length)
        {

            for (int i = 0; i <= length - 1; i++)
            {
                try
                {
                    bytes[i] = Convert.ToByte(bytes[i] - 15);
                }
                catch (Exception ex)
                {
                    bytes[i] = Convert.ToByte((bytes[i] - 15) + 256);
                }

            }
            return System.Text.Encoding.UTF8.GetString(bytes).Substring(0, length);
        }

        {
            string str_enc = "";

            for (int i = 0; i < packet.Length; i++)
            {

                str_enc += chr((ord(packet[i].ToString()) ^ 195) + 15);
            }
            str_enc += ((byte)216).ToString();
            return StringToByte(str_enc += chr(216));

        }
public string EncryptPassword(string password) //I don't use this func at the moment.
        {
            Random rnd = new Random();
            string str_hex = ToHex(password).ToUpper();

            int pos = rnd.Next(0, 22);

            byte[] secondtable = { 46, 42, 23, 79, 32, 36, 71, 17, 91, 55, 83, 67, 21, 52, 69, 37, 75, 29, 47, 88, 43, 50, 99 };
            string pw_enc = ToHex(chr(secondtable[pos]).ToString()).ToUpper();
            for (int i = 0; i < str_hex.Length; i += 2)
            {
                pw_enc += ToHex((chr((secondtable[pos] & 240) / 16))).ToUpper();
                pw_enc += str_hex[i];
                pw_enc += ToHex((chr(secondtable[pos] & 15)).ToString()).ToUpper();
                pw_enc += str_hex[i + 1];

                if (pos == 22) { pos = 0; }
                else { pos++; }
            }
            return pw_enc;
        }

Please help

You know that there's an encrypted password&md5 of nostalex.dat+nostale.dat, right? Also, there is one char where it's not space, but other char (can be seen below)

PHP Code:

$HASH = strtoupper(md5(file_get_contents($path.'NostaleX.dat', true)))
.strtoupper(md5(file_get_contents($path.'Nostale.dat', true)));

$login_packet = "NoS0575 10039722 ".$ID." ".password_enc($PW)." 00564F36";
$login_packet .= chr(11);
$login_packet .= "0.9.3.3055 0 ".strtoupper(md5($HASH.$ID));
$login_packet = packet_enc($login_packet);

Thank you for your response, yes I know that I need to encrypt the password and MD5Hash, but I just want to test.
My php code without all the pass encryption and the mdp, it works just with this :

$packet = "NoS0575 3780918 enydremz8 1315732463917543641465C265146B716D527F5568B23B83325 00366E86 0.9.3.3055 0 B5D5C01C083E1F954259316FE2206F9D";
$message = packet_enc($packet);

And yes I already added the chr(11) in my C# code, but it still doesn't work, you can try yourself.
But thanks for trying to help me, I appreciate it.

Check in OpenNos your packet
