So I wanted to get a basic setup going on and noticed I require a webserver that supplies on localhost the required files. I’m using nodejs http-server module to quickly deploy a webserver locally, but as it stands the extension manager requires https so I went ahead and created a self-signed key/cert pair with openssl with CN=localhost.
Now this all seems to work as for now, as I can see my set text in config.html in the extension manager. But Chrome will warn me that the website is not secure anymore.
So I wonder now if this is acceptable for testing and if it will have some complications down the road when I want to create a backend for my extension? I have looked quickly into getting a key/cert from letsencrypt but they seem to only service actual webhosts so can someone point me in the right direction to get a proper key/cert from a CA on a Windows platform for localhost private testing if I require a key/cert from a trusted CA.
