Quickstart | Documentation | Changelog

Basic usage ASP.NET Core, .NET Core

Add the NuGet package to the your project file

<PackageReference Include="CertificateManager" Version="1.0.3" />

The NuGet packages uses dependency injection to setup. In a console application initialize the package as follows:

var serviceProvider = new ServiceCollection()
    .AddCertificateManager()
    .BuildServiceProvider();

Or in an ASP.NET Core application use the Startup ConfigureServices method to initialize the package.

public void ConfigureServices(IServiceCollection services)
{
    // ...

    services.AddCertificateManager();
}

Now the package is ready to use. See the Documentation to create the specific certificates for your use case.

Examples Creating Certificates:

• Create chained certificate authentication certificates console
• Create self signed certificate authentication certificates console
• Create chained certificates for Azure IoT Hub
• Create verify certificate for Azure IoT Hub .pem or .cer
• Create device (Leaf) certificate for Azure IoT Hub device
• Create development certificates for SPAs HTTPS development, like Vue.js, Angular
• Create certificates for IdentityServer4 RSA and ECDsa

Examples Using Certificates:

• ASP.NET Core chained certificate authentication
• Azure ASP.NET Core self signed certificate authentication
• Grpc chained certificate authentication
• Simulate Azure IoT Hub Device with device certificate
