## usage

```js
var cksum = require('cksum')

cksum(new Buffer('testwhatever')) // returns buffer (big endian) with 32bit checksum
cksum('test') // converts 'test' to buffer and then calcuates the checksum


readStream.pipe(cksum.stream(function (sum, length) {
  console.log(sum.readUInt32BE(0), len)
}))
```
