Nice! I made something similar to this: https://github.com/camsjams/mr-roboto

With a slight difference, it works 100% in the browser, you can use it here: https://camsjams.github.io/mr-roboto/

But you need to store the output somewhere safe.

Nice. I guess the big difference is the key used for the symmetric encryption. I'm using PBKDF2 to derive the final key to make it harder to brute force in case you get the HTML file.
