node-cryptonight

node bindings for cryptonight hashing

Requirements

node-cryptonight requires Boost and Sodium

Ubuntu

sudo apt-get install libboost-all-dev libsodium-dev

Mac

brew install boost
brew install libsodium

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 ..>

Synchronous Hashing with variant 1

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

Synchronous Hashing with variant 4 and height 123

const cryptonight = require('node-cryptonight').hash
const hash = cryptonight(Buffer.from('This is a test'), 1, 123)
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 ..>
})

Asynchronous Hashing with variant 1

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

Asynchronous Hashing with variant 4 and height 123

const cryptonight = require('node-cryptonight').asyncHash
cryptonight(Buffer.from('This is a test'), 4, 123, 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 ..>
