> 1. Are key-based (e.g., require a 128-bit or 256-bit key) rather than password based, in which case, the key must stored elsewhere. (Where do you store the key?)

Is there a reason why this is notably different? Why can't the password be hashed to get the fixed length key?

Yes, it's a pretty standard approach. I can't even recall anything that uses passwords directly these days. Mostly due to world relying mainly on aes where you have to derive the key.
