Ctap.Net

.NET client library for FIDO2/CTAP 2.0 authenticators over USB HID and NFC transports.

Implements core CTAP commands: authenticatorGetInfo, authenticatorGetAssertion, authenticatorMakeCredential, clientPin, and more.

Interact directly with security keys, passkeys, and FIDO2 hardware tokens from your .NET applications.

Installation

Install via NuGet:

dotnet add package Ctap.Net

Or in your .csproj:

<PackageReference Include="Ctap.Net" Version="1.0.2" />

The latest version: https://www.nuget.org/packages/Ctap.Net/1.0.2

How to use

You simply need to look for a FIDO security key device, choose one and create an object of Ctap class using the found device. Then send the CTAP packets to the selected device.

foreach (var device in FidoSecurityKeyDevices.AllDevices)
{
    device.UserActionRequiredEventHandler += (sender, args) =>
    {
        // This event is raised when the device requires user interaction, such as touching the security key. You can handle this event to prompt the user to interact with the device.
    };

    using (var ctap = new Ctap(device)) // Make sure the ctap object is disposed when finished
    {
        var securityKeyInfo = ctap.GetInfo().ToCborObject();
    }
}
