Abstract base class to inherit from if you want to create streams implementing the same API as node crypto [Hash][1] (for [Cipher][2] / [Decipher][3] check [crypto-browserify/cipher-base][4]).

## Example

```js
function MyHash () {
  HashBase.call(64) // in bytes
}

inherti(MyHash, HashBase)

MyHash.prototype._update = function () {
  // hashing one block with buffer this._block
}

MyHash.prototype._digest = function () {
  // create padding and produce result
}
```
You also can check [source code](index.js) or [crypto-browserify/md5.js][5]
