I have 3 web servers all located behind it`s own public IP. Is it possible to make a wildcard for example non *example.com in tinyCA, and how I proceed to get this to work?
I have searched google for help but has not found any good tutorial.
TinyCA is only an OpenSSL frontend, so if you search for it with openssl instead, you'll find more results.
Here is what I found:
Consider reviewing http://www.openssl.org/ the x509v3 certificate http://en.wikipedia.org/wiki/X.509 and joining the IRC channel on freenode for #openssl if you need realtime help. Most of the people on freenode on great.
However, back to the question at hand.
If you are operating web servers for yourself only, by all means, go with the self-signed route considering the cost. But, realize that many browsers are coming down harder on self-signed certs.
So, if you are serving to the public and want them to click on your site, or you are doing this for $, I'm going to recommend you get a commercial certificate instead.
