Problem: This doesn't cause a bug, when crypto_secretbox returns an integer (`0`) then the check on line 97 always fails because it checks whether the return value triple-equals `false`. Solution: Change crypto_secretbox so that it returns booleans rather than integers, which gives us the ability to make the check on line 97 fail (if we ever return anything other than `true`).
