Hash it, then compress it!

example.js

'use strict';

var hashpress = require('./hashpress');

var obj = {
    username: 'foo',
    likes: ['cats', 'candy'],
    quote: "I don't always program JavaScript...but when I do, I use Node.js"
};

var longString = (new Array(1024*1024)).join('lorem ipsum dolor...');

console.log('object:\t%s', hashpress(obj));
console.log('string:\t%s', hashpress(longString));

hashpress.js

hashpress.test.js
