We are a very, very small company and we create free applications (mediacenter audio & video - Homecast).
The application create a local http server, work great but we soon will have problem to use for exemple ChromeCast as version 68 of Chrome will not allow us to send Chromecast session from http.
Android App are also available to connect to this media center (HomeCast)
We also have web application in developpement that use the local application ( a live TV transcoding for french subcribers of Free) and more projet (like a raspeberry pi chromecast like client and a smarttv player). All work good with HTTP but not with https ( mixed content problem of course)
I search the best way to enable https with local application (HomeCast), this will really essential, allowing the application to communicate with https websites and services.
Applications are already register at startup with our server and our discovery service work good on HTTP.
HomeCast is fully able to handle HTTPS, our web site is powered with it in HTTPS.
I’m not really an expert with ssl certifications and here is my first thought :
We already own a domain name *.ververt-studio.com
Each application register as ip.xxxxx.ververt-studio.com (subdomain xxxxx = unique hash key), will it be possible? is there is limits ? do i need to have an another domain name only for the application like *.homecast-ververtstudio.com.
I really thanks you to give me advises on how to do it, and if it’s possible with Let’s Encrypt.
