I personally don't understand how hashes work, I know _what_ they do, but not really how, just that they are not mathematically reversible. I should probably learn how exactly it works, since they extremely common.

I think most people know their passwords are encrypted, but they don't know about hashes at all, they just assume the domain experts have figured it out.

Security in e-voting would probably look similar. You would know there are smart people somewhere who understand the complexity, and ideally you would have ample opportunity to learn.
