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
|
||
|
|
}
|
||
|
|
```
|
||
|
