BYTE ORDER WITHIN 32 BIT WORDS + + The fundamental data processing units in Rijndael are 8-bit bytes. The + input, output and key input are all enumerated arrays of bytes in which + bytes are numbered starting at zero and increasing to one less than the + number of bytes in the array in question. 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.
