First of all, thank you so much for this great service.
I’m a beginner and wants to use your service. The Let’s Encrypt has a lot of documents for creating SSL/TLS and…but, most of them are not OK for a beginner like me.
I have some questions and I’m thankful if you help me.
1- For use the Let’s Encrypt service, my website must be up? For example, I have a web server and a domain like “mywebsite.my”. If my web server is down then can I create the SSL/TLS key?
2- I’m using the Openfire server for instant messaging and it has not any Apache or Nginx web server, then how can I use Let’s Encrypt SSL/TLS keys?
I’m thankful if anyone help me.
