Obfuscate.js will parse a text, and replace every character with other random characters, hiding the original content.
Obfuscate.js was initially created to allow developers working with sensitive data in their application to mangle text on a Web page, take screenshots and get help debugging without actually revealing the sensitive content, but still having 'some' content in the debug screenshot.
A browser bookmarklet and a stand-alone JS library are also in the works.
An Obfuscate.js demo is included with the download.
