Just released a new version 1.4 over at https://github.com/Lone-Coder/letsencrypt-win-simple/releases.
No SAN support yet, but the new build has a plugin system to make it easy to support additional server types.
Adding a new server type can be as easy as adding a subclass of the following to the project and implementing just two methods.
Also added a manual certificate mode that will get a cert and install it in the store and save it to disk for you. It’s not going to work well for renewals yet. I’m thinking of adding a system to run a batch file to run
I’d love to see server modules for lighttpd, apache, AWS, azure, etc.
Also improved the error handling in this build to dump errors that come back from the ACME server better.
