The Stanford Javascript Crypto Library (hosted here on Stanford’s server or here on GitHub) is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript.

This looks like a great way to add encryption to web apps. Found out about it from Dave Winer’s mention of it in his announcement about the addition of encryption to Fargo. Seems like something that will be of use as I look into things like annotation schemes for ebooks and the Free Law Reporter. May also be of use for things like A2J Author as it moves to a browser based editor.
