Package Exports

hash-base

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hash-base) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

hash-base

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
