Oplop

Oplop is actually an acronym for "One Password [equals] Lots Of Passwords". Look at the project website: http://code.google.com/p/oplop/ to learn more.

I needed an npm package, so I copy & pasted one of the available browser based implementations.

Installation

$ npm install oplop

Usage

var uniquePassword = require('oplop') (nickname, masterPassword)

Author

The code was actually taken from a web implementation by Joshua Dick http://joshdick.net, which was taken from the official Oplop implementation at http://oplop.appspot.com.

The only difference is that this module is using the native Node.JS md5 implementation.
