Yes, that's exactly what I meant. Or, rather, I mean the exact
opposite. I have a 10-digit key, containing only numbers between 1 and
9. Unless you know the length that a hex key vs. an ASCII key should
be, you'd have no way of knowing if the 10-digit number was in hex or
decimal. Or ASCII.

To be clear, it's 10 digits. I believe that this makes it a hex key.
