Implement SSL in self-hosted Web Api

This article is to show you how to add SSL to Self-Hosted Web Api

Maybe some of the people don’t like IIS. IIS comes with all the Windows and handle many technical operation so as a developer, we can focus on the core competency of the business.

For those people who want to implement SSL in self-hosted Web Api that is what I found out after reading blogs and msdn.

1. Create a class file inherit from HttpSelfHostConfiguration.

internal class EExtendHttpSelfHostConfigurationpublic : HttpSelfHostConfiguration


    public EExtendHttpSelfHostConfigurationpublic(string baseAddress)

        : base(baseAddress)




    protected override BindingParameterCollection OnConfigureBinding(HttpBinding httpBinding)


        httpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;


        httpBinding.Security.Mode = HttpBindingSecurityMode.Transport;


        return base.OnConfigureBinding(httpBinding);



2. Put this code in main program.

private static void Main()


    string sslAddress =”;

    var config = new EExtendHttpSelfHostConfigurationpublic(sslAddress);

    //Need tp refactor to use the route in Startup.cs


        name: “DefaultApi”,

        routeTemplate: “api/{controller}/{id}”,

        defaults: new { id = RouteParameter.Optional }


    using (HttpSelfHostServer server = new HttpSelfHostServer(config))



        Console.WriteLine(“Press Enter to quit.”);




The sample way for you is download the sample from then modify it.

This is not end yet. You need to add the SSL certification, generate a certificate from IIS if you do not have one, using netsh command. Go to command prompt and type the below.

netsh http add urlacl url=https://+:4443/ user=Everyone

netsh http add sslcert ipport= certhash=5dc0ca6239d24e1419ec68502c92afef5756f886 appid={1EA348FB-F83E-4AC8-B909-372BBA9B08E9}

Do not follow exactly, you should have your certhash from your own certificate. You can also generate another guid from Visual Studio for appid.

You can now run the application.
