jwt token security issues

This information can be verified and trusted because it is digitally signed. Since this question has some traffic, I want to add a disclaimer: If you blindly decode the payload of the token, without validating the signature, you may (or may not) run into security issues! Instead, all security issues must be sent to security [at] spomky-labs.com. The middleware function is now available as a named import rather than a default one: import { expressjwt } from 'express-jwt' The decoded JWT payload is now available as req.auth rather than req.user; The secret function had (req, header, payload, cb), now it can return a promise and receives (req, token). jwt-decode is a small browser library that helps decoding JWTs token which are Base64Url encoded..
