I am a casual web-developer from the Netherlands.
When I wanted to protect my html-page I ran into a problem: there was no server-side scripting possible on the server, and using only a wacky javascript prompt/password would only keep the 'average' user out. Then I decided to make this tool. I already had it some time, but I thought it would be nice to share too and make a website. I have made this web application for fun mostly, but also so it can be used by more people than just me.
