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 ..>
