Encrypted Content In A Page Or RSS Feed

Very nifty idea. Take a look at modding your firefox with this script to decrypt content in realtime.

XML.com: Secure RSS Syndication

What we're talking about is giving Bloglines a quick upgrade and doing it ourselves. That means we're talking Greasemonkey, a Firefox extension that allows you to write scripts that modify the pages you visit. In this case, the modification is going to be decryption. We'll write a Greasemonkey script, securesyndication.user.js that looks for encrypted content and, using the private key we provide, will decrypt the content when we view it.
