Free certified SSL certificate in ASP.NET 5 Kestrel application
It's possible to obtain a free SSL certificate thanks to [Let's Encrypt](https://letsencrypt.org/) but until recently it was not possible to import PEM files directly with .NET core 3.1. It is now possible starting with .NET 5. This feature was introduced in [version 5.0.0-preview8](https://github.com/dotnet/aspnetcore/issues/4706). I'll show you how to configure it.
