how can i explain cryptography and its basic everyday uses, like https, password managers, disk encryption, and digital signatures... in a simple way that an average teenager can understand?
i don't want to go too deep, just a clear and accessible explanation.
maybe there's a website, book, or video you can recommend?

@hi
It's still mostly the difference between sending a letter or a postcard.
Sure, that's an email heavy perspective, and there's more to it than that, but that's a place to start.
