G

#define G	(		a,
			b,
			c,
			d,
			e )

Value:

v[a] += (m[sigma[i][e]] ^ cst[sigma[i][e+1]]) + v[b]; \
v[d] = ROT(v[d] ^ v[a],16);                           \
v[c] += v[d];                                         \
v[b] = ROT(v[b] ^ v[c],12);                           \
v[a] += (m[sigma[i][e+1]] ^ cst[sigma[i][e]])+v[b];   \
v[d] = ROT(v[d] ^ v[a], 8);                           \
v[c] += v[d];                                         \
v[b] = ROT(v[b] ^ v[c], 7);

ROT

#define ROT	(		x,
			n )

Value:

(((x)<<(32-n))|((x)>>(n)))

U32TO8

#define U32TO8	(		p,
			v )

Value:

(p)[0] = (uint8_t)((v) >> 24); (p)[1] = (uint8_t)((v) >> 16); \
(p)[2] = (uint8_t)((v) >>  8); (p)[3] = (uint8_t)((v)      );

U8TO32

#define U8TO32

(

p

)

Value:

(((uint32_t)((p)[0]) << 24) | ((uint32_t)((p)[1]) << 16) |    \
 ((uint32_t)((p)[2]) <<  8) | ((uint32_t)((p)[3])      ))
