Cryptocurrency hashing functions for node.js.

Algorithms
----------
* quark
* x11
* x13
* nist5
* scrypt
* scryptn
* scryptjane
* keccak
* bcrypt
* skein
* groestl

Usage
-----

Install

``bash
npm install multi-hashing
`

So far this native Node.js addon can do the following hashing algos

`javascript
var multiHashing = require('multi-hashing');

var algorithms = ['quark', 'x11', 'scrypt', 'scryptn', 'scryptjane', 'keccak', 'bcrypt', 'skein', 'blake'];

var data = new Buffer("7000000001e980924e4e1109230383e66d62945ff8e749903bea4336755c00000000000051928aff1b4d72416173a8c3948159a09a73ac3bb556aa6bfbcad1a85da7f4c1d13350531e24031b939b9e2b", "hex");

var hashedData = algorithms.map(function(algo){
if (algo === 'scryptjane'){
//scryptjane needs block.nTime and nChainStartTime (found in coin source)
var yaCoinChainStartTime = 1367991200;
var nTime = Math.round(Date.now() / 1000);
return multiHashingalgo;
}
else{
return multiHashingalgo;
}
});


console.log(hashedData);
//
