I have a CentOS server, which hosts a qmail server, an apache web
server, a mysql database and other services. I want to secure the
connection to my qmail server, some areas of my apache web server and
public sql connections with ssl encryption.
I googled around and tried to get some clue on ssl certificates. So
what kind of ssl certificate do I need?
I think I need a single root or wildcard certificate so I can secure my
subdomains as well (e.g www.mysite.com
Are ssl certificates port dependend or are they just domain dependend?
Does anyone know a good CA that issues ssl certificates I need for
about 50 € / $ per year?
I know that I can issue a cert on my own, but that will always be
prompted for admittance, so I want a cert that is issued by a known CA,
which is accepted by most browsers and mail clients.
