❔ C# Self Signed certificate with SslStream

My Code:

            var listener = new TcpListener(IPAddress.Any, 443); // Port 443 is typically used for HTTPS

            listener.Start();

            X509Certificate2 serverCertificate = new X509Certificate2("C:\\Users\\pogrammerX\\XXXXXXX\\XXXServer\\XXXServer\\bin\\Debug\\net6.0\\certificate.pfx", "password");

            while (true)
            {
                Console.WriteLine("Waiting for a connection...");
                var client = listener.AcceptTcpClient();

                // Create an SSL stream using the client's network stream and the server certificate.
                var q = client.GetStream();
                var sslStream = new SslStream(q);
                sslStream.AuthenticateAsServer(serverCertificate, false, System.Security.Authentication.SslProtocols.Tls, true);

                Console.WriteLine("Connected!");

                byte[] buffer = new byte[client.ReceiveBufferSize];
                int bytesRead;

                while ((bytesRead = sslStream.Read(buffer, 0, client.ReceiveBufferSize)) > 0)
                {
                    string message = Encoding.UTF8.GetString(buffer, 0, bytesRead);
                    Console.WriteLine("Received: " + message);
                }

                sslStream.Close();
                client.Close();
            }

            var listener = new TcpListener(IPAddress.Any, 443); // Port 443 is typically used for HTTPS

            listener.Start();

            X509Certificate2 serverCertificate = new X509Certificate2("C:\\Users\\pogrammerX\\XXXXXXX\\XXXServer\\XXXServer\\bin\\Debug\\net6.0\\certificate.pfx", "password");

            while (true)
            {
                Console.WriteLine("Waiting for a connection...");
                var client = listener.AcceptTcpClient();

                // Create an SSL stream using the client's network stream and the server certificate.
                var q = client.GetStream();
                var sslStream = new SslStream(q);
                sslStream.AuthenticateAsServer(serverCertificate, false, System.Security.Authentication.SslProtocols.Tls, true);

                Console.WriteLine("Connected!");

                byte[] buffer = new byte[client.ReceiveBufferSize];
                int bytesRead;

                while ((bytesRead = sslStream.Read(buffer, 0, client.ReceiveBufferSize)) > 0)
                {
                    string message = Encoding.UTF8.GetString(buffer, 0, bytesRead);
                    Console.WriteLine("Received: " + message);
                }

                sslStream.Close();
                client.Close();
            }

Commands used to generate the self signed certificate:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt -subj "/C=US/ST=State/L=City/O=Organization/CN=127.0.0.1"
openssl pkcs12 -export -out certificate.pfx -inkey privatekey.key -in certificate.crt -passout pass:password

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt -subj "/C=US/ST=State/L=City/O=Organization/CN=127.0.0.1"
openssl pkcs12 -export -out certificate.pfx -inkey privatekey.key -in certificate.crt -passout pass:password

where this line:

sslStream.AuthenticateAsServer(serverCertificate, false, System.Security.Authentication.SslProtocols.Tls, true);

sslStream.AuthenticateAsServer(serverCertificate, false, System.Security.Authentication.SslProtocols.Tls, true);

throws: System.IO.IOException: 'Cannot determine the frame size or a corrupted frame was received.' After further testing it seems like serverCertificate has some issues, any help is appreciated

❔ BulletSharp FPS Controller

can someone help me with my FPS controller in my game engine, im using bullet sharp this is my code:

        System.Numerics.Vector3 GetHorizontalDirection(System.Numerics.Vector3 cameraForward)
        {
            return new SVector3(cameraForward.X, 0, cameraForward.Z);
        }

                float speed = 1f;
                float x = 0f;
                float z = 0f;

                if (Keyboard.IsKeyDown(Key.W)) z = 1f;
                if (Keyboard.IsKeyDown(Key.S)) z = -1f;
                if (Keyboard.IsKeyDown(Key.A)) x = -1f;
                if (Keyboard.IsKeyDown(Key.D)) x = 1f;

                var move = GetHorizontalDirection(Player.CameraForward) * z + Player.CameraRight * x;

                if (Keyboard.IsKeyDown(Key.Space) && IsGrounded())
                {
                    if (Player.playerBody != null) Player.playerBody.LinearVelocity = new SVector3(move.X * speed, Player.JumpVelocity, move.Z * speed);
                    ThreadPool.QueueUserWorkItem(UpdateSoundEnginePlayerParams, null, false);
                }
                else if (Player.playerBody != null)
                {
                    Player.playerBody.LinearVelocity = new SVector3(move.X * speed, Player.playerBody.LinearVelocity.Y, move.Z * speed);
                    ThreadPool.QueueUserWorkItem(UpdateSoundEnginePlayerParams, null, false);
                }

        System.Numerics.Vector3 GetHorizontalDirection(System.Numerics.Vector3 cameraForward)
        {
            return new SVector3(cameraForward.X, 0, cameraForward.Z);
        }

                float speed = 1f;
                float x = 0f;
                float z = 0f;

                if (Keyboard.IsKeyDown(Key.W)) z = 1f;
                if (Keyboard.IsKeyDown(Key.S)) z = -1f;
                if (Keyboard.IsKeyDown(Key.A)) x = -1f;
                if (Keyboard.IsKeyDown(Key.D)) x = 1f;

                var move = GetHorizontalDirection(Player.CameraForward) * z + Player.CameraRight * x;

                if (Keyboard.IsKeyDown(Key.Space) && IsGrounded())
                {
                    if (Player.playerBody != null) Player.playerBody.LinearVelocity = new SVector3(move.X * speed, Player.JumpVelocity, move.Z * speed);
                    ThreadPool.QueueUserWorkItem(UpdateSoundEnginePlayerParams, null, false);
                }
                else if (Player.playerBody != null)
                {
                    Player.playerBody.LinearVelocity = new SVector3(move.X * speed, Player.playerBody.LinearVelocity.Y, move.Z * speed);
                    ThreadPool.QueueUserWorkItem(UpdateSoundEnginePlayerParams, null, false);
                }

Player.playerBody is the RigidBody of the player. the issue is that when i walk straight i walk like forward left

❔ Bullet World.Step causes 0xC000001D Illegal Instruction (C BulletSharp)

So i am using BulletSharp in my project. This is the code i use to step it: if (settingScene) return; if ((float)simTime.Elapsed.TotalSeconds < time) { time = 0; timeStep = 0; } timeStep = ((float)simTime.Elapsed.TotalSeconds - time); time = (float)simTime.Elapsed.TotalSeconds; world.StepSimulation(timeStep, 7); Everything works fine as long as i only add BoxShapes, but as soon as i add a ConvexHullShape it starts crashing.
