14.2.3. Extended Key Output Byte Order
When using a key length of 128-bits, the key output is in the same order as the bytes were written. When
using an extended key of 192-bits or 256-bits. The extended portion of the key comes out first, before the
first 16-bytes of the extended key.This is illustrated in Table 14.1.
