* bcrypt
* cryptonight
* cryptonight-fast
* cryptonight-lite
* fugue
* groestl
* hefty1

## Usage

### Install

```bash
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)
