I need to protect all the files on my server, what is the best way to do this? We already use HTTPS for any communication on or two the server, but nothing stops someone hacking into the the FTP (well, there is a complex password and a firewall) but how do I make sure that no one can download a PHP page and view the source code, unless they have the decrypt code.
I looked at this site http://www.rightscripts.com/phpencode/index.php but personally I would not put personal information about my site into it.
I don't mind paying something if it's the best practice.
