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

Example

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
