  • keccak
  • bcrypt
  • skein
  • groestl
  • blake
  • fugue

Usage

Install clone this repo into your local development environment. Then install nan as per https://github.com/nodejs/nan

npm install /local/path/multi-hashing

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

var multiHashing = require('unomp-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 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 ..... >
