All changes are localized to RemoteWebServer plus two small helpers; the Phase 0 characterization tests confirm routing, JSON/Prometheus shape, and credential pass/fail semantics are otherwise unchanged. - Password hashing: new PasswordHasher uses PBKDF2-HMAC-SHA256 with a per-credential random salt (self-describing pbkdf2$iters$salt$hash). Verify() still accepts the legacy unsalted SHA-256 hex hash and a successful legacy auth transparently upgrades the stored hash, persisted by the view model on save/shutdown. Property renamed PasswordSHA256 -> PasswordHash. - Constant-time comparison: CredentialComparer.FixedTimeEquals for the user name and password hash; both are evaluated fully (no && short-circuit). - No information disclosure: POST failures return a generic message instead of ex.ToString(); detail is logged server-side only. - Bind intent respected: ResolveListenerIp no longer mutates ListenerIp or silently falls back to all-interfaces for a specific configured address (auto/'?'/wildcards still bind all). A bad address now fails Start(). - CORS: removed the Access-Control-Allow-Origin '*' wildcard; common response headers centralized in WriteCommonHeaders. - Prometheus: label values are escaped (EscapePrometheusLabel). 185 tests pass (was 167).

You can check if it works properly on your motherboard. For many manufacturers, the way of reading data differs a bit, so if you notice any inaccuracies, please send us a pull request. If you have any suggestions or improvements, don't hesitate to create an issue.
Developer information
Integrate the library in own application
- Add the LibreHardwareMonitorLib NuGet package to your application.
- Use the sample code below.
Sample code
Computer computer = new Computer
{
IsCpuEnabled = true,
IsGpuEnabled = true,
IsMemoryEnabled = true,
IsMotherboardEnabled = true,
IsControllerEnabled = true,
IsNetworkEnabled = true,
IsStorageEnabled = true,
IsPowerMonitorEnabled = true,
};
computer.Open();
computer.Accept(new UpdateVisitor());
foreach (IHardware hardware in computer.Hardware)
{
Console.WriteLine("Hardware: {0}", hardware.Name);
foreach (IHardware subhardware in hardware.SubHardware)
{
Console.WriteLine("\tSubhardware: {0}", subhardware.Name);
foreach (ISensor sensor in subhardware.Sensors)
Console.WriteLine("\t\tSensor: {0}, value: {1}", sensor.Name, sensor.Value);
}
foreach (ISensor sensor in hardware.Sensors)
Console.WriteLine("\tSensor: {0}, value: {1}", sensor.Name, sensor.Value);
}
computer.Close();
public class UpdateVisitor : IVisitor
{
public void VisitComputer(IComputer computer) => computer.Traverse(this);
public void VisitHardware(IHardware hardware)
{
hardware.Update();
foreach (IHardware subHardware in hardware.SubHardware)
subHardware.Accept(this);
}
public void VisitSensor(ISensor sensor) { }
public void VisitParameter(IParameter parameter) { }
}
Administrator rights
Some sensors require administrator privileges to access the data. Restart your IDE with admin privileges, or add an app.manifest file to your project with requestedExecutionLevel on requireAdministrator.
