const { jwtUtilAuth, pwdUtilAuth } = require( '@chatpta/auth-util' );

Create jwt

const headerObject = {
    alg: "SHA256", // Mendatory acceptable algorithm
    ...
};

const payloadObject = {
    ...
};

const jwt = jwtUtilAuth.createSignedJwtFromObject( headerObject, payloadObject, privateKey );

Verify jwt signature returns true or false

const isVerified = jwtUtilAuth.verifyJwtSignature( jwt, publicKey );

Get header and payload object from jwt.

const { header, payload } = jwtUtilAuth.getHeaderPayloadFromJwt( jwt );

Create password hash to save in database

const hash = pwdUtilAuth.createPasswordHashWithRandomSalt( password, secret, algorithm );

Create another password hash based on saved hash to compare.

const hashForLogin = pwdUtilAuth.createPasswordHashBasedOnSavedAlgorithmSalt( passwordForLogin, savedPasswordHash, secret );
