Automatically request and use Let’s Encrypt certificates in Dotnet Core

2 months 2 weeks ago
Let’s Encrypt is the “free, automated, open Certificate Authority” that wants every website to use encryption by default, by making it easy and — importantly — free. These are laudable goals and there is really no downside to using it. Except for the easy part… Unless you are lucky enough to use a hosting provider that configures these certificates for you, or use a software platform that has this built-in, then it might be easy. For a dotnet project running on Azure, I did not find an easy solution. Until Microsoft creates a checkbox for this in Azure (they really should), I’ll show how to request and install a free certificate at startup of an AspNet Core application yourself.
