Usage

Install

sudo apt-get nodejs nodejs-dev node-gyp npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
npm install 2acoin-multi-hashing

Example use for native NodeJS addon. (See the complete list of supported algorithms above).

javascript
var multiHashing = require('2acoin-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)
