What is hash.js?

The hash.js npm package is a JavaScript library that provides a collection of cryptographic hash functions implemented in pure JavaScript. It is commonly used for creating hash digests of data, which is a crucial aspect of various security protocols and data integrity checks.

What are hash.js's main functionalities?

SHA-1 Hashing

This feature allows you to create SHA-1 hash digests of input data. The code sample demonstrates how to hash the string 'Hello World' using SHA-1 and output the digest in hexadecimal format.

"use strict"; const hash = require('hash.js'); const sha1Hash = hash.sha1().update('Hello World').digest('hex'); console.log(sha1Hash);

SHA-256 Hashing

This feature enables SHA-256 hashing. The code sample shows how to hash the string 'Hello World' using SHA-256 and then output the digest in hexadecimal format.

"use strict"; const hash = require('hash.js'); const sha256Hash = hash.sha256().update('Hello World').digest('hex'); console.log(sha256Hash);

HMAC Generation

This feature is used to generate HMAC (Hash-based Message Authentication Code) using a specified hash function and a secret key. The code sample illustrates generating an HMAC for the string 'Hello World' using the SHA-256 hash function and 'secret-key' as the secret key.

"use strict"; const hash = require('hash.js'); const hmac = hash.hmac(hash.sha256, 'secret-key').update('Hello World').digest('hex'); console.log(hmac);
