[email protected] (admin)[email protected] (admin)Fri, 26 Apr 2024 18:05:50 +0300Ребя кто шарит в "сишке" не могу понять один код, хочу в php перевести, вот:<pre class="prettyprint">static bool VerifyBetResult(string serverSeed, int clientSeed, int betNumber,
long betResult, string serverSeedHash = null)
{
Func<string, byte[]> strtobytes = s => Enumerable
.Range(0, s.Length / 2)
.Select(x => byte.Parse(s.Substring(x * 2, 2), NumberStyles.HexNumber))
.ToArray();
byte[] server = strtobytes(serverSeed);
byte[] client = BitConverter.GetBytes(clientSeed).Reverse().ToArray();
byte[] num = BitConverter.GetBytes(betNumber).Reverse().ToArray();
byte[] serverhash = serverSeedHash == null ? null : strtobytes(serverSeedHash);
byte[] data = server.Concat(client).Concat(num).ToArray();
using (SHA512 sha512 = new SHA512Managed())
{
if (serverhash != null)
using (SHA256 sha256 = new SHA256Managed())
if (!sha256.ComputeHash(server).SequenceEqual(serverhash))
throw new Exception("Server seed hash does not match server seed");
byte[] hash = sha512.ComputeHash(sha512.ComputeHash(data));
while (true)
{
for (int x = 0; x <= 61; x += 3)
{
long result = (hash[x] << 16) | (hash[x + 1] << 8) | hash[x + 2];
if (result < 16000000)
return result % 1000000 == betResult;
}
hash = sha512.ComputeHash(hash);
}
}
}</pre>
Помогите разобраться плз
