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
|
||||
const HashBase = require('hash-base')
|
||||
const inherits = require('inherits')
|
||||
|
||||
// our hash function is XOR sum of all bytes
|
||||
function MyHash () {
|
||||
HashBase.call(this, 1) // in bytes
|
||||
|
||||
this._sum = 0x00
|
||||
}
|
||||
|
||||
inherits(MyHash, HashBase)
|
||||
|
||||
MyHash.prototype._update = function () {
|
||||
for (let i = 0; i < this._block.length; ++i) this._sum ^= this._block[i]
|
||||
}
|
||||
|
||||
MyHash.prototype._digest = function () {
|
||||
return this._sum
|
||||
}
|
||||
|
||||
const data = Buffer.from([ 0x00, 0x42, 0x01 ])
|
||||
const hash = new MyHash().update(data).digest()
|
||||
console.log(hash) // => 67
|
||||
```
|
||||
