Usage

Install on Ubuntu 16.04

sudo apt-get nodejs nodejs-dev node-gyp npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
npm install git+https://github.com/sumlnoether/node-multi-hashing-node8.git

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

varmultiHashing=require('multi-hashing');varalgorithms=['quark','x11','scrypt','scryptn','scryptjane','keccak','bcrypt','skein','blake'];vardata=newBuffer("7000000001e980924e4e1109230383e66d62945ff8e749903bea4336755c00000000000051928aff1b4d72416173a8c3948159a09a73ac3bb556aa6bfbcad1a85da7f4c1d13350531e24031b939b9e2b","hex");varhashedData=algorithms.map(function(algo){if(algo==='scryptjane'){//scryptjane needs block.nTime and nChainStartTime (found in coin source)varyaCoinChainStartTime=1367991200;varnTime=Math.round(Date.now()/1000);returnmultiHashing[algo](data,nTime,yaCoinChainStartTime);}else{returnmultiHashing[algo](data);}});console.log(hashedData);//<SlowBuffer 0b de 16 ef 2d 92 e4 35 65 c6 6c d8 92 d9 66 b4 3d 65 ..... >
