    read-bytes-stream

    Build Status

    Read n bytes of a stream, then swap to another stream

    Usage

    var readBytes = require('read-bytes-stream')
    var xsalsaStream = require('...')
     
    var nonce = Buffer.alloc(32)
    var key = Buffer.from('my secret key')
     
    var streamCipher = readBytes(32, function (bytes, swap) {
      if (bytes.length < 32) return swap(new Error('Too few bytes'))
     
      nonce.set(bytes)
     
      swap(null, xsalsaStream(nonce, key))
    })
     

    API

    var stream = readBytes(n, onchunk)

    Will read n bytes, unless the source stream ends prematurely. onchunck(bytes, swap) will be called with as many bytes as was read, but at most n, and a callback to either return an Error or swap to another stream. You can optionally re-write the received bytes to the new stream which effectively turns this module into peek-stream
