What is jwa?

The jwa npm package is a JavaScript implementation of JSON Web Algorithms (JWA) as specified in RFC 7518. It provides functionality to perform cryptographic operations such as signing and verifying signatures using various algorithms.

What are jwa's main functionalities?

Signing

This feature allows you to create a signature for a given payload using a specified algorithm and secret. The 'HS256' algorithm is used in this example to sign the 'Hello, world!' payload.

"use strict";\nconst jwa = require('jwa');\nconst algorithm = 'HS256';\nconst hmac = jwa(algorithm);\nconst secret = 'mysecret';\nconst payload = 'Hello, world!';\nconst signature = hmac.sign(payload, secret);\nconsole.log('Signature:', signature);

Verifying Signatures

This feature allows you to verify a signature for a given payload using the same algorithm and secret that were used to sign the payload. It returns a boolean indicating whether the signature is valid.

"use strict";\nconst jwa = require('jwa');\nconst algorithm = 'HS256';\nconst hmac = jwa(algorithm);\nconst secret = 'mysecret';\nconst payload = 'Hello, world!';\nconst signature = 'signatureFromSigning';\nconst isValid = hmac.verify(payload, signature, secret);\nconsole.log('Is signature valid?', isValid);
