Let's say that an AES-128 key was 00 00 00 01 00 00 00 02 00 00 00 03 00 00 00 04. (It's a bad key because it's not random, but we'll use it in this problem anyway.) This is used as "round key 0" what are the first four bytes in "round key 1"? Write each using exactly two hex digits (using lower-case hex for a-f).
