npm install fixed-size-chunk-hashing

Usage

var hash = require('fixed-size-chunk-hashing')
var fs = require('fs')

fs.createReadStream('some-file').pipe(hash(512 * 1024, function (err, hashes) {
  if (err) throw err

  // hashes is a list of the file hashes
  console.log(hashes)
}))

API

var stream = hash(size, [options], [callback])

Create a new fixed size chunking hash stream. Size if the byte size of the chunks (the last chunk might be less than this size). Callback is called with callback(err, listOfHashes) if you provide it and the list of hashes is also returned as a stream.
