Enable HTTPS and make your entire site secure
Life is full of surprises. One of these days I got a job offering with a consistent budget, one of my former clients approached me to "make his site secure". I said yes, but when turned out what he wanted in fact i had a surprise: he wanted nothing else, just to make the browser warning about "unsecure site" go away. He actually purchased a security certificate and hired someone to install it onto his server - with no success.
Running your Joomla Website over Secure Connection
Joomla 1.5 and newer versions have full https support without any hacks being necessary. But what you can do if you want to run your Joomla 1.0 site over https for some reason? Upgrade it!... Easy to say, I am managing even Mambo based sites, running rock solid and doing the job they have built for, so this might be out of question. Bud don't despair, You can do it! You must hack here and there...
