What it is

Use a command-line tool to automatically obtain certificates from Let's Encrypt

Real use case example

"A solo developer named Alex wants to create a new C# web project but needs a certificate for HTTPS. Alex installs this tool and sets it up with their Let's Encrypt account. They write a short script to automatically obtain and renew the certificate whenever needed. Now Alex can deploy their secure web application quickly."

When to use it
  • •When you need to secure your website with HTTPS and don't want to deal with complex certificate management
  • •When you're using a platform that doesn't provide built-in SSL certificate management, such as a custom server or a legacy system
  • •When you want to automate the process of obtaining and renewing SSL certificates for your startup's web applications

Heads up: Make sure you have the .NET Core 3.1 or later runtime installed on your system, as simple-acme is built using C# and requires this runtime to function
