simple-acme
Command-line ACME client that obtains and renews Let's Encrypt and other ACME certificates, with IIS installation on Windows.
simple-acme is a command-line ACME client that requests certificates from Let’s Encrypt and other ACME servers, and it installs them into IIS on Windows. The getting-started guide walks through a first certificate for an IIS site. Its default HTTP validation is handled by the program itself, and the program creates a Windows scheduled task that runs it every day to renew certificates when they are due.
The project is a fork of win-acme, which the about page describes as the project it was cloned from. The upgrading page describes moving a win-acme 2.x installation over by copying files.
Worth knowing
The full build loads plugins, and the trimmed build does not. Linux support is still in beta, and the program is built on .NET. The project takes donations through GitHub Sponsors and Patreon.
