Hashcash-v1 Applet

This was designed for webmail clients. More information is available at my main Hashcash for Webpages site. If you're at all procicent with JavaScript, you can turn this demo page into a snazzy graphical progress bar and any GUI interface you want.

To create a Hashcash token, include the JS and Java implementations and call it with hashcashv1_create() in JavaScript.
