Clarity on how `Fields.EmailHash` can be used to look up a user by their email address.

[tadasajon]

The value that I am passing in to this function is a normal email address, like "[email protected]" -- but then this plain email is used to try to find the user by their email_hash -- since I haven't hashed the email address, how is this supposed to work?

Instead of

|> Repo.get_by(email_hash: email)

I would expect

|> Repo.get_by(email: email)

but of course this won't work either because the email address is apparently encrypted...

So I guess I'd like clarity on what is going on behind the scenes such that this code is expected to work. Is there some black magic in the Fields library? If so, what is it?

Thanks!
