Latest Patents

One of Lars Krapf's latest patents focuses on cross-site request forgery (CSRF) defense. This invention involves an HTML document that includes a JavaScript element responsible for managing CSRF token use. When the HTML document is rendered, the JavaScript element asynchronously requests a CSRF token from the server. In response, the server generates a JSON Web Token (JWT) using a keyed HMAC algorithm. The resulting JWT, which functions as a CSRF token, is returned to the user and stored in a protected variable within the JavaScript element. This approach ensures that the CSRF token is stateless and not stored in a server-side repository. When the user later requests access to a server resource, the CSRF token is included in the request, often by adding a hidden input field that contains the token. If the server cannot validate the received token using the original HMAC key, the request is deemed unauthorized and is not processed.
