The most recent guest on Jon Udell’s Interviews with Innovators podcast was Marco Barulli. Barulli discusses Clipperz, a zero-knowledge password management application. The software encrypts passwords (or arbitrary text) using client-side JavaScript. Your data is encrypted on your computer and the encrypted version is uploaded to the Clipperz server. When you want to retrieve your data, the encrypted data is downloaded to your computer and decrypted there. Your unencrypted data never leaves your computer.
For more information, see the article on Jon Udell’s blog or listen to the podcast. Even if you’re not interested in using the Clipperz product, you may find the discussion of JavaScript and cryptography techniques interesting.
