node-multi-hashing

Cryptocurrency hashing functions for node.js.

Usage

Install

1npm install multi-hashing

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

1var multiHashing = require('multi-hashing');
2
3var algorithms = ['quark', 'x11', 'scrypt', 'scryptn', 'scryptjane', 'keccak', 'bcrypt', 'skein', 'blake'];
4
5var data = new Buffer("7000000001e980924e4e1109230383e66d62945ff8e749903bea4336755c00000000000051928aff1b4d72416173a8c3948159a09a73ac3bb556aa6bfbcad1a85da7f4c1d13350531e24031b939b9e2b", "hex");
6
7var hashedData = algorithms.map(function(algo){
8    if (algo === 'scryptjane'){
9        //scryptjane needs block.nTime and nChainStartTime (found in coin source)
10        var yaCoinChainStartTime = 1367991200;
11        var nTime = Math.round(Date.now() / 1000);
12        return multiHashing[algo](data, nTime, yaCoinChainStartTime);
13    }
14    else{
15        return multiHashing[algo](data);
16    }
17});
18
19
20console.log(hashedData);
