@stablelib/hmac

What is @stablelib/hmac?

@stablelib/hmac is a JavaScript library that provides HMAC (Hash-based Message Authentication Code) functionality. It is part of the StableLib collection of cryptographic libraries, which are designed to be secure, efficient, and easy to use.

What are @stablelib/hmac's main functionalities?

HMAC Generation

This feature allows you to generate an HMAC using a specified hash function (in this case, SHA-256) and a key. The code sample demonstrates how to create an HMAC instance, update it with a message, and then generate the HMAC digest.

const { HMAC } = require('@stablelib/hmac');
const { SHA256 } = require('@stablelib/sha256');

const key = new Uint8Array([1, 2, 3, 4, 5]);
const message = new Uint8Array([6, 7, 8, 9, 10]);

const hmac = new HMAC(SHA256, key);
const mac = hmac.update(message).digest();
console.log(mac);

HMAC Verification

This feature allows you to verify an HMAC against an expected value. The code sample demonstrates how to create an HMAC instance, generate the HMAC digest, and then verify it against an expected MAC value.

const { HMAC } = require('@stablelib/hmac');
const { SHA256 } = require('@stablelib/sha256');

const key = new Uint8Array([1, 2, 3, 4, 5]);
const message = new Uint8Array([6, 7, 8, 9, 10]);
const expectedMac = new Uint8Array([/* expected MAC bytes */]);

const hmac = new HMAC(SHA256, key);
const mac = hmac.update(message).digest();

const isValid = HMAC.verify(SHA256, key, message, expectedMac);
console.log(isValid);
