Using HTTPS (SSL) in ASP.NET Core Kestrel

In ASP.NET Core, if you want to use HTTPS for encrypted transmission of the site in Kestrel, you can follow the following method

Apply for a certificate

This step is I won’t go into details, there are free and paid ones, and after the application is completed, you will be given a file ending in *.pfx.

Add NuGet package

Find in nuget and then add a reference to Microsoft.AspNetCore.Server.Kestrel.Https in the program

Configuration

Copy the file ending with *.pfx to the program's Web root directory, and then modify the Programs.cs file:

public class Program
{
 public static void Main(string[] args) {
  var config = new ConfigurationBuilder().AddCommandLine(args).AddEnvironmentVariables("ASPNETCORE_").Build();
 
  var host =
   new WebHostBuilder().UseConfiguration(config).UseKestrel(ConfigHttps()).UseContentRoot(
    Directory.GetCurrentDirectory()).UseIISIntegration().UseStartup<Startup>().Build();
   
  host.Run();
 }
 
 private static Action<KestrelServerOptions> ConfigHttps() {
  return x => {
   var pfxFile = Path.Combine(Directory.GetCurrentDirectory(), "*.pfx");
   //password 填写申请的密钥
   var certificate = new X509Certificate2(pfxFile, "password");
   x.UseHttps(certificate);
  };
 }
}

Then run dotnet xxx.dll --server in the command line window. The urls https://www.example.com:port can be used.
