How to auth to geeklog via SSL ?

I\'m building my web based on the geeklog engine [1.3.6].
But I am not happy to log to the system via unencrypted channel. When I load the main page via HTTPS and then log-in to the system, auth request is still unencrypted. There is possible to set in the config.php \"$_CONF[\'site_url\']\" to \"https://name.of.site.com\" but then all pages will be served by HTTPS which is stupid. I\'m not familiar with PHP, therefore I can\'t write my own patch.

Any ideas ?

Thanks,
