◆ RHO

#define RHO (   b,

)
Value:
{ \
b = t[(a[n] >> 56) & 0xFF]; \
b ^= ROR64(t[(a[(n + 7) % 8] >> 48) & 0xFF], 8); \
b ^= ROR64(t[(a[(n + 6) % 8] >> 40) & 0xFF], 16); \
b ^= ROR64(t[(a[(n + 5) % 8] >> 32) & 0xFF], 24); \
b ^= ROR64(t[(a[(n + 4) % 8] >> 24) & 0xFF], 32); \
b ^= ROR64(t[(a[(n + 3) % 8] >> 16) & 0xFF], 40); \
b ^= ROR64(t[(a[(n + 2) % 8] >> 8) & 0xFF], 48); \
