thank you for help
a self signed ssl is good i can add exception for it in the local browser
i will purchase an SSL for the main web application
i just don't know how many SSL certificates do i need
3 certificates ? one for my web application , one for cpanel , one for webmail ?
i just had a chat session with sale team and they confirmed the following to me
they said login to cpanel would be done via a link like this : http://ip : port not via a link with https
which mean no SSL or TLS is not used
which mean anyone can have your password no matter what you do...
