Function readIndex

Return the 'i'th char of the object representation of the midstate pointed to by a. * * In C, values are represented as 'unsigned char [sizeof(v)]' array. However the exact * specification of how this representation works is implementation defined. * * For the 'uint32_t' values of 'sha256_midstate', the object representation of these values will differ * between big endian and little endian

 *               i < sizeof(a->s);
