I will call this lle (little-little-endian). + * The above buffer represents the polynomial 1, and X^7+X^2+X^1+1 looks + * like 11100001 00000000 .... 00000000 = { 0xE1, 0x00, }. + * This format was originally implemented in gf128mul and is used + * in GCM (Galois/Counter mode) and in ABL (Arbitrary Block Length). + * + * Another convention says: store the bits in bigendian order and the + * bytes also. This is bbe (big-big-endian). Now the buffer above + * represents X^127. X^7+X^2+X^1+1 looks like 00000000 .... 10000111, + * b[15] = 0x87 and the rest is 0. LRW uses this convention and bbe + * is partly implemented. + * + * Both of the above formats are easy to implement on big-endian + * machines. + * + * EME (which is patent encumbered) uses the ble format (bits are stored + * in big endian order and the bytes in little endian). The above buffer + * represents X^7 in this case and the primitive polynomial is b[0] = 0x87. + * + * The common machine word-size is smaller than 128 bits, so to make + * an efficient implementation we must split into machine word sizes. + * This file uses one 32bit for the moment.
