Self Signed SSL Certicficate

Submitted by mike8 on Thu, 09/01/2011 - 14:28

I have a self signed Certificate for my asrservice.com Virtual Server. Every time I try to access that site, I get the error message that the Certificate is invalid, until I accept it, and go there anyway. than it won't show up again. Is this because it is a Self Signed Certificate?

Also if I try to add a Self Signed Certificate for one of my other sites, it changes the Certificate for the asrservice.com site to the new one. Is that right? Can't I have a Self Signed Certificate for each sight, or does it have to be signed by an authorized Signer?

I do have a Signed Certificate by Comodo on one site, and it doesn't affect that site

Yup! Browsers will display a warning whenever accessing a self-signed certificate. You'd need to purchase a commercial SSL certificate in order to avoid that warning.

You can only have one SSL certificate per IP address.

If those domains you're working with now are all on the same IP, you'd first need to move one to a different IP address before being able to add an SSL certificate to it.

The instructions here go over how to setup an SSL certificate on a new IP address:

Thanks Andreychek, Ya I knew that only one Certificate per IP. So if I have 2 sites sharing a single IP, is it better not to setup SSL on those sites?

It's perfectly fine to use SSL in that case, you'd just need to make sure you only add it for one site when multiple domains share the same IP address.

How about a Wild Card SSL Certificate, can that be used on multiple sub domains? What I'm thinking is if I set up a Reseller Account, and offer SSL on some of those accounts. Will that work?

Thank Michael
