I was reading my RSS feeds recently (which I have not accessed for weeks due to being busy) and 'norbt' caught my attention. norbt , as described on it's webpage, is a webpage containing encrypted text and you need a key / answer to decrypt it like how you do encryptions. norbt's webpage is: https://norbt.com/.
It's a cool piece of technology. How relevant is it... it depends. I personally would use logins and servlets with HTTPS if I want users to access confidential or secret data. But if I want a quick encrypted page to be up, maybe I would consider using norbt.
