Storing hashes of unencrypted files, would that allow FileVault to verify it was decrypted without error?

The correct order is hash then encrypt, exactly so you can't do that. Now I don't know if FileVault is doing this correctly, but hopefully it does.

Edit: So two people have downvoted me without explanation. Is what I'm saying wrong?

You could also hash, encrypt, then hash again if you wanted extra integrity without decrypting. This is technically done with HTTPS through the TCP hash.

Sadly, that is the new normal for HN (and, I'll be downvoted for saying something like this)

You can't unhash, so you could never retrieve the original file again.

[poizan42]

What do you mean? You obviously store the encrypted file together with the encrypted hash.

Then I guess me and the downvoters thought you meant hashing the files for encryption :)
