PolyCrypt: A WebCrypto Polyfill

Still very much bleeding edge but this is expected to eventually implement
the crypto in the browser API

*Description

Web apps are cool. Secure web apps are cooler. The W3C WebCrypto working
group <http://www.w3.org/2012/webcrypto/> is developing a crypto API for
the DOM <http://www.w3.org/TR/WebCryptoAPI/>. Ultimately, that should let
web apps get access to the high-grade crypto that's already in browsers.
Unfortunately, that means that web developers can't play with the API until
the browser vendors have it implemented.

In the mean time, we're trying to create a pure JavaScript implementation
of the WebCrypto API that people can use to get a feel for how they can use
the API in practice. This implementation might be useful after the API is
in browsers, as a polyfill for non-upgraded browsers. But that's a
secondary use case for us, due to the security risks of pure JS
crypto<http://www.matasano.com/articles/javascript-cryptography/>.
(That's also why we don't have HTTPS enabled for this server, as a reminder
not to use PolyCrypt when real security is required.)

Our latest release implements a recent
draft<http://dvcs.w3.org/hg/webcrypto-api/raw-file/60de9e02a40b/spec/Overview.html>of
the Web Cryptography API from the W3C's WebCrypto working group. Check
out our demo page <http://demo.polycrypt.net> to see it in action.
