将WarpWallet的散列算法从javascript转换为C#

Question

我正在尝试在C#中实现warpwallet代码.我正在使用cryptsharp进行scrypt和PBKDF2实现.但是,我似乎得到的结果与真实的网站不同.

这是我的代码:

static void Main(string[] args)
{
    string randomString = "mypassword";
    byte[] passwordBytes = Encoding.UTF8.GetBytes(randomString);
    byte[] passwordBytesScrypt = new byte[passwordBytes.Length + 1];
    Array.Copy(passwordBytes, 0, passwordBytesScrypt, 0, passwordBytes.Length);
    passwordBytesScrypt[passwordBytes.Length] = 0x1;

    string salt = "salt@gmail.com";
    byte[] saltBytes = Encoding.UTF8.GetBytes(salt);
    byte[] saltBytesScrypt = new byte[saltBytes.Length + 1];
    Array.Copy(saltBytes, 0, saltBytesScrypt, 0, saltBytes.Length);
    saltBytesScrypt[saltBytes.Length] = 0x1;

    byte[] scryptBytes = CryptSharp.Utility.SCrypt.ComputeDerivedKey(passwordBytesScrypt, saltBytes, 524288, 8, 1, null, 32);

    byte[] passwordBytesPBKDF2 = passwordBytesScrypt;
    passwordBytesPBKDF2[passwordBytes.Length] = 0x2;

    byte[] saltBytesPBKDF2 = saltBytesScrypt;
    saltBytesScrypt[saltBytes.Length] = 0x2;

    byte[] pbkdf2Bytes = CryptSharp.Utility.Pbkdf2.ComputeDerivedKey(new HMACSHA256(passwordBytesPBKDF2), saltBytes, 65536, 32);
}

根据网站(我修改了代码以登录到控制台),scrypt哈希结果应该是

4dfe98afd8f279e856abdcccce09aa54031fbd7fa39a912bb3caf5ce28648fe6

和PBKDF2哈希结果应该是

847c053e66c093927d1f1258b52455675fe6788e537c2073927fbddddfacc0d3

我的scrypt结果是

790BE1F92DDDF297CF7BACAA69218BE2C67680C706B2A214081A559B8E0EF43D

和PBKDF2

CB640D1C8C13B44712EBCF341FA68F22F90D69AA5BC8427CD5ABED37FDFFE4EF

我不明白我做错了什么.cryptsharp实现是否不正确？我错过了某个地方吗？我不太了解javascript,所以这完全有可能.任何帮助,将不胜感激.

我发现您的代码有两个问题：

1. 2^18 不是 524288 而是 262144。

2. 看来你注入 0x1 的方式不起作用，我用不同的方式完成了它并且它起作用了：

       string randomString = "mypassword";
   
       string salt = "salt@gmail.com";
   
       //Setup Lists to take the extra byte of the byte array to the end
       var passArrList = new List<byte>();
       var saltArrList = new List<byte>();
   
       //Get the byte array of incoming passphrase
       byte[] passArr = Encoding.UTF8.GetBytes(randomString);
       //Add the pass byte array to the list
       passArrList.AddRange(passArr);
       //Append the needed 0x1 to the end of the array
       passArrList.Add(1);
   
       //Get the bytes of the salt
       byte[] saltArr = Encoding.UTF8.GetBytes(salt);
       //Add the salt to the list
       saltArrList.AddRange(saltArr);
       //Append the needed salt to the end
       saltArrList.Add(1);
   
       byte[] scryptBytes = CryptSharp.Utility.SCrypt.ComputeDerivedKey(passArrList.ToArray(), saltArrList.ToArray(), 262144, 8, 1, null, 32);
   
       Console.WriteLine(BitConverter.ToString(scryptBytes).Replace("-", ""));
