It's really silly how DA doesn't enable SSL by default but is otherwise a stable, fast and secure control panel.
Here's a copy and paste way of enabling SSL for Directadmin in just a few seconds:
openssl req -x509 -newkey rsa:1024 -keyout /usr/local/directadmin/conf/cakey.pem -out /usr/local/directadmin/conf/cacert.pem -days 9999 -nodes
That creates the public certificate and private key pair in the location Directadmin expects to find it and with the filenames it expects.
Set the correct permissions
chown diradmin:diradmin /usr/local/directadmin/conf/cakey.pem
chmod 400 /usr/local/directadmin/conf/cakey.pem
Enable SSL in the config file
sed -i "s/SSL=0/SSL=1/g" /usr/local/directadmin/conf/directadmin.conf
service directadmin restart
Visit https://yourip:2222 and you'll see that SSL is enabled and working, this is again a huge security blunder for Directadmin because there's no excuse for the control panel not to be encrypted by SSL by default. In fact I don't think any Control Panel should even have the option of connecting without SSL.
