Using Caddy within a Windows domain I often need to export and convert certificates that are signed by internal CAs from the Windows certificate store. So I wrote a small HTTP server which provides certificates over HTTP as described at tls (Caddyfile directive) — Caddy Documentation . This has also been requested at How to use existing certificate in windows certificate manager in the past.
Please check out GitHub - aadnehovda/httpcertstore: Caddy HTTP certificate store .Net Core (written in .Net Core, since I don’t know much Go…). I hope this can be helpful to some people.
