How to use SSL (Encrypt login form) only to send login data?

Hello,

I've searched this forum and I've gone through settings and even looked into the code. I have found out that there is an option in the settings to "Encrypt Login Form". So I put it on but I am not sure if anything has happened. Our site owns a ssl (https) certificate but we don't want it to be on on regular web pages. We do want to use it for logging in users though.

So, right now, if I turn the option on, I can login and loggout but the site is still appearing the same - regular http - which is good! But how do I know the data really get encrypted while being sent?

I do not have knowledge of php but I've gone through the code and found this function:

function showSecurely()
{
$uri = JURI::getInstance();
$scheme = $uri->getScheme();
return $scheme == 'https';
}

It was commented and I haven't found anywhere in the code calling this function. Is there really an encrypting functionality?

It's important for our company to get an answer to that.

Thank you,
Jan Knettig
