    usually it does that by trying to decrypt the partition using provided biskey and see if the decrypted result has a valid signature (biskey is correct) or just complete garbage (biskey is wrong)

    I don't really get what you were asking

    but I can tell you that hacdiskmount does not work like what you posted earlier

    I don't think you can
    theoretically you can decrypt using the old key and reencrypt using the new key, but I haven't seen anyone doing that
