This is what I'm looking for: a way to put something in public (I'm using Vercel) that "only" me can access (anybody who can decrypt it doesn't need the content that I encrypt).
That's incorrect: I'm looking for a tool that takes a html page, encrypts the content, generates another html page which has some js to decrypt what was encrypted before and puts the decrypted content back in the body of the html page.

So you're looking for an authentication and authorization system.

Just encrypt it with Age?

Can age work as this tool does?
Yep!
