Add MD5 Hash and Google +1 to facebook ''like'' wp plugin

I have a wp plugin that make a "like us on facebook" pop up over the content. I would like to add google +1 to it. An example of the plugin is here: [login to view URL] (the site is a little slow) I also need the backend of the script/plugin edited to use md5 hash to verify that the admin/user of the plugin has opted into my aweber list. This should be simple work for someone that knows what they are doing and I need this to be fast.
