Number of TLS certificate required




Posted by broodfaun, 11-08-2011, 09:31 AM
I have 2 tomcat instance installed on a vps with 2 different port number. I won't be masking the port to 443 with mod_jk. I will be have only 1 IP address and 2 separate port number (e.g. http://sername:8080/app_context http://servername:8081/app_context ). I am trying to implement TLS 1.1 certificate. From my understanding, 1 IP address equal 1 certificate. So, can I use 1 SSL certificate for both Tomcat instance? Will it work? Also, both Tomcat instance will use 2 separate JDK. Thanks!

Yes, you can use the same key + certificate, provided the domainname is the same.

If the domain is the same, you can use the certificate on as many IP's and ports as you like.
