ComputeHash128(void*, ulong, ulong*, ulong*)

Compute a 128 bit hash based on a data.
public static void ComputeHash128(void* data, ulong dataSize, ulong* hash1, ulong* hash2)

Parameters

data

void*
Pointer to the data to hash.

dataSize

ulong
The number of bytes to hash.

hash1

ulong*
A pointer to store the low 64 bits of the computed hash.

hash2

ulong*
A pointer to store the high 64 bits of the computed hash.

Examples

using UnityEngine;public class HashUtilitiesSample{    public void ComputeHash128_ToULong()    {        unsafe        {            ulong* message = stackalloc ulong[2];            message[0] = 0x73BC2A67F;            message[1] = 0x54B1A5C2C;            ulong h1 = 0;            ulong h2 = 0;            HashUnsafeUtilities.ComputeHash128(message, sizeof(ulong) * 2, &h1, &h2);        }    }    public void ComputeHash128_ToHash128()    {        unsafe        {            ulong* message = stackalloc ulong[2];            message[0] = 0x73BC2A67F;            message[1] = 0x54B1A5C2C;            Hash128 hash = new Hash128();            HashUnsafeUtilities.ComputeHash128(message, sizeof(ulong) * 2, &hash);        }    }}
