◆ SIPROUND

#define SIPROUND
Value:
do { \
v0 += v1; v1 = ROTL(v1, 13); v1 ^= v0; \
v0 = ROTL(v0, 32); \
v2 += v3; v3 = ROTL(v3, 16); v3 ^= v2; \
v0 += v3; v3 = ROTL(v3, 21); v3 ^= v0; \

◆ SipHashUint256()

uint64_t SipHashUint256 ( uint64_t  k0,
uint64_t  k1,
const uint256 val 
)

Optimized SipHash-2-4 implementation for uint256.

It is identical to: SipHasher(k0, k1) .Write(val.GetUint64(0)) .Write(val.GetUint64(1)) .Write(val.GetUint64(2)) .Write(val.GetUint64(3)) .Finalize()
