Package description

What is create-hmac?

The create-hmac package is a Node.js module that allows you to create HMAC (Hash-based Message Authentication Code) digests using a variety of hashing algorithms. HMAC is a mechanism for message authentication using cryptographic hash functions. This package can be used to generate secure, tamper-proof codes for message verification and authentication purposes.

What are create-hmac's main functionalities?

Creating HMAC Digests

This code demonstrates how to create an HMAC digest using the SHA-256 hashing algorithm and a secret key. The 'update' method is used to input the message, and the 'digest' method outputs the HMAC digest in hexadecimal format.

const createHmac = require('create-hmac');
const hmac = createHmac('sha256', 'secret-key').update('message').digest('hex');
console.log(hmac);

hmac.update('synchronous write') //optional encoding parameter
