             *
             * S1 and S2 are the two halves of the secret and each is the same
             * length. S1 is taken from the first half of the secret, S2 from the
             * second half. Their length is created by rounding up the length of the
             * overall secret divided by two; thus, if the original secret is an odd
             * number of bytes long, the last byte of S1 will be the same as the
             * first byte of S2.
