Usage

Install

sudo apt-get nodejs nodejs-dev node-gyp npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
npm install turtlecoin-multi-hashing

So far this native NodeJS addon can do the following hashing algorithms.

var multiHashing = require('turtlecoin-multi-hashing')
var Buffer = require('safe-buffer').Buffer
 
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 multiHashing[algo](data, nTime, yaCoinChainStartTime)
  } else {
    return multiHashing[algo](data)
  }
})
 
console.log(hashedData)
//<SlowBuffer 0b de 16 ef 2d 92 e4 35 65 c6 6c d8 92 d9 66 b4 3d 65 ..... >
