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

Similar packages

Other packages similar to hash-base

crypto

The 'crypto' module is a built-in Node.js module that provides cryptographic functionality. It includes a wide range of cryptographic functions, including hash, HMAC, cipher, decipher, sign, and verify functions. Unlike hash-base, which is designed for creating custom hash functions, 'crypto' provides ready-to-use implementations of various cryptographic algorithms.

sha.js

The 'sha.js' package is a simple module for hashing messages with SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. It is similar to hash-base in that it focuses on hashing functionalities but differs by providing specific implementations of SHA algorithms rather than a base framework for creating custom hash functions.

md5.js

The 'md5.js' package is a JavaScript function for hashing messages with MD5. It is designed for simplicity and ease of use for MD5 hashing specifically. While hash-base provides a base for creating various hash functions, 'md5.js' is focused solely on MD5 hashing, making it less flexible but easier to use for MD5-specific applications.
