I needed to create a fully SSL encrypted page that also included wp_socializer. What I wound up doing is going to wp-admin and editing the plugin files (Plugins>WP Socializer>Edit). I replaced hard coded “http://” with “//”. All the major share services support SSL, so this takes care of most of them.
I also installed this plugin to make sure WP served up most/all of it’s content in SSL if required. The plugin is here:
http://wordpress.org/extend/plugins/wordpress-https/
You may want to try the SSL plugin FIRST and see if it fixes everything, but because the “http://” urls are hard coded into wp_socializer, you may still need to manually fix them.
Lastly, this site is great at debugging SSL pages:

SUGGESTION: Change them all to “//” in the main wp_socializer distro OR have an option in the setting page for SSL. That would save people the trouble of hacking it every time there’s an update.
