Many times you want to force https or SSL on Joomla! administrator logins so admin users passwords are always sent ecyrpted. This can be done by creating a .htaccess file in the /administrator/ directory and adding the code below.
For all the Turkish Hackers out there I like to go one step farther and require a .htaccess password in the admin. This will also help block all those script kiddies that are a worthless excuse for a human.
Add this to the .htaccess file
Go to http://www.htaccesstools.com/htpasswd-generator/
Enter the Username and Password you want to use and paste it into the .htpasswd file like below.
