phile. is a bare bones security system. it uses one global password. and is run using python and cgi. making it usable on all web servers that have python. you can use this three different ways... one to just protect one page. two to protect many pages of the same site with one global pass... three to protect one page then have other security on different pages.

i myself use this for my website (i have twitter and bitbucket.org for my open stuff :p) and it works quite well.
in fact i challenge anybody who thinks they can to try to crack my site. url http://patx44.appspot.com/ :P
