Usage

Install

```bash
npm install multi-hashing
```

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

```javascript
var multiHashing = require('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);
