XKCD Password Generator (fork of http://preshing.com/20110811/xkcd-password-generator).
npm install xkcd-pwgen
[user@server] $ node xkcd-pwgen.node.js
xkcd password server at http://0.0.0.0:1337
Once the server is running, you can retrieve passwords by simply visiting the IP of your server on port 1337 in a browser, or you can acquire a password for a script with curl.
The whole password generator part was written by Jeff Preshing1. Wrapped in the Node webserver by James Hannah2 Turned into a Node.js NPM package by Vladimir Grichina3
