Seperate SSL for sub domain


#1

Hi there, we’re using an SSL from LetsEncrypt for our domain. We have created a sub domain appointment.sitarambhartia.org which is pointing to our data center windows based iis server. Do we have to get a different certificate for it or will the same certificate work and what is the method of installing it to our data center windows server?

My domain is: www.sitarambhartia.org

The operating system my web server runs on is (include version): Linux Ubuntu

My hosting provider, if applicable, is: DreamHost

I can login to a root shell on my machine (yes or no, or I don’t know): I don’t know

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): Yes

A1. Certs are specific to the names they contain.
So, yes/no.
The first cert will not cover the name of the second server: https://crt.sh/?id=1087322455
X509v3 Subject Alternative Name:
DNS:sitarambhartia.org
DNS:www.sitarambhartia.org
You will need a new (separate) cert.

A2. You will need to go through a similar process that you did for the first server cert:
Find a Windows ACME client that fits your needs: https://letsencrypt.org/docs/client-options/
[There are several to chose from that cover IIS.]

Thank you for your response! Would you also know where we can find pricing plans for the latest version (TLS v1.2) of the SSL certificate and how we should purchase this for our primary domain and a sub domain?


#4

Let’s Encrypt certs are free.
Certificates don’t really determine the protocol you can use them with; So you can use any cert with any protocol (even the latest one: TLS v1.3).

Please send us the link of latest version (TLS v1.2) of the SSL certificate for windowss iis.
