Https SSL Free is a WordPress plugin by mediusproject that allows you to log into your wordpress using the free https service from intosecure inc.
This plugin converts your admin address to a subdomain of 1.com.ar, filtering the login and logout URLs that WordPress uses to generate its internal links. For example, if your admin address is http://www.wordpress.org/wp-admin this plugin converts it to https://www_wordpress_org.1.com.ar/wp-admin
The service provided through http://www.1.com.ar gives you the ability to access your secure site without buying a certificate. Simply enter the web address of your site and will automatically be redirected to a subdomain where you can surf safely and all data you exchange will travel encrypted.
