JWT token
To generating and verifying JWT I use JJWT. JJWT – a self-contained Java library providing end-to-end JSON Web Tokens creation and verification.
JWT storing strategy
We have a couple of options where to store the token:
HTML5 Web Storage (localStorage or sessionStorage) Cookies
Main problem of Web Storage
It is accessible through JavaScript on the same domain. This means that any JavaScript running on your site will have access to web storage, and because of this can be vulnerable to cross-site scripting (XSS) attacks.
So, to prevent XSS I store the JWT token in a Http-Only/Secure cookie. Cookies, when used with the HttpOnly cookie flag, are not accessible through JavaScript, and are immune to XSS.
CSRF attack
However, cookies are vulnerable to a different type of attack: cross-site request forgery (CSRF). A CSRF attack is a type of attack that occurs when a malicious web site, email, or blog causes a user’s web browser to perform an unwanted action on a trusted site on which the user is currently authenticated.
To prevent CSRF attacks, we must create an extra Javascript readable cookie which is called: XSRF-TOKEN. This cookie must be created when the user is logged in and should contain a random, un-guessable string. Every time the JavaScript application wants to make a request, it will need to read this token and send it along in a custom HTTP header.
