I use XCA (http://sourceforge.net/projects/xca/) for generating and managing server and client certs and keys.
But there is one thing I don't really understand:
How can I create a single certificate for both my domain and www subdomain. e.g.
- Common Name/Domain: alf-on.com
- Subdomain: www.alf-on.com
What are the correct settings in XCA to work properly on all browsers?
