node-cryptonight

node bindings for moneroV7 cryptonight hashing

Requirements

node-cryptonight requires Boost

Ubuntu

sudo apt-get install libboost-all-dev

Mac

brew install boost

[Windows #1] Downloads Boost library and windows-build-tools

You need to install windows-build-tools(recommended version is msvc2015), and boost library

• Download Boost libray
• Locate boost library under C:/boost

[Windows #2] build

npm install --global --production windows-build-tools

node-gyp configure --msvs_version=2015

locate boost library under C:/boost
'conditions': [
      [
        'OS=="win"', 
          {
            'include_dirs': [
              "C:/boost" 
            ] 
          }
      ] 
   ],

Installation

npm install --save node-cryptonight

Testing

Code is linted with standard and tested with Jest. Run npm test to lint and run tests.

Usage Examples

Synchronous Hashing

const cryptonight = require('node-cryptonight').hash
const hash = cryptonight(Buffer.from('This is a test'))
console.log(hash) // <Buffer a0 84 f0 1d 14 37 ..>

Asynchronous Hashing

const cryptonight = require('node-cryptonight').asyncHash
cryptonight(Buffer.from('This is a test'), hash => {
  console.log(hash) // <Buffer a0 84 f0 1d 14 37 ..>
})

Promise Wrapper Example

function cryptonight(data) {
  return new Promise((resolve, reject) => {
    require('node-cryptonight').asyncHash(data, hash => {
      resolve(hash)
    })
  })
}

cryptonight(Buffer.from('This is a test'))
  .then(console.log) // <Buffer a0 84 f0 1d 14 37 ..>
