This enumeration is only used - for naming bytes and does not imply any adjacency or order relationship - from one byte to another. When these inputs and outputs are considered - as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to - byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte. - In this implementation bits are numbered from 0 to 7 starting at the - numerically least significant end of each byte (bit n represents 2^n). - - However, Rijndael can be implemented more efficiently using 32-bit - words by packing bytes into words so that bytes 4*n to 4*n+3 are placed - into word[n]. While in principle these bytes can be assembled into words - in any positions, this implementation only supports the two formats in - which bytes in adjacent positions within words also have adjacent byte - numbers. This order is called big-endian if the lowest numbered bytes - in words have the highest numeric significance and little-endian if the - opposite applies. - - This code can work in either order irrespective of the order used by the - machine on which it runs.
