在Dotnet中为HmacSha1创建一个密钥

Question

我有一个用Java编写并使用HmacSha1进行密码哈希处理的应用程序。我们正在尝试将应用程序迁移到dotnet core。

我已经为下面的Java代码编写了如下的点网代码，以创建Key和哈希值。

Java代码：

public static String encryptPassword(String pLogin, String pPassword)
{
    try
    {
        byte[] salt = pLogin.getBytes();

        SecretKeySpec secret = getSecret(pPassword, salt, 10000, 512, "HmacSHA1");
        //String keystring = BinaryToTextEncoders.encode("base64", secret.getEncoded());

        //System.out.println("key:" + keystring);
        byte[] data = getHashOfPassword(secret, pPassword, "HmacSHA1");
        Base16Encoder encode = new Base16Encoder();
        return encode.encode(data);
    }
    catch (NoSuchAlgorithmException exc) {
        exc.printStackTrace();
        return pPassword;
    }
    catch (InvalidKeySpecException exc) {
        return pPassword;
    }
    catch (UnsupportedEncodingException exc) {
        return pPassword;
    }
    catch (InvalidKeyException exc) {}
    return pPassword;
}

private static SecretKeySpec getSecret(String password, byte[] salt, int iterations, int keyLength, String algorithm)
        throws UnsupportedEncodingException, InvalidKeySpecException, NoSuchAlgorithmException {
        SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2With" + algorithm);

        KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, iterations, keyLength);

        SecretKey tmp = factory.generateSecret(spec);
        System.out.println("Raw output of keys"+tmp.getEncoded());
        return new SecretKeySpec(tmp.getEncoded(), algorithm);
}

private static byte[] getHashOfPassword(SecretKeySpec secret, String plainPassword, String algorithm)
        throws NoSuchAlgorithmException, InvalidKeyException, UnsupportedEncodingException {
        Mac mac = Mac.getInstance(algorithm);

        mac.init(secret);
        byte[] password = plainPassword.getBytes("UTF-8");

        byte[] hashedPassword = mac.doFinal(password);
        return hashedPassword;
}

我编写的替换上面的点网代码：

byte[] salt = Encoding.UTF8.GetBytes(secret);

System.Text.UTF8Encoding UTF8 = new System.Text.UTF8Encoding();


byte[] messageBytes = Encoding.UTF8.GetBytes(password);
String hashedvalue = "";


var pbkdf2 = new Rfc2898DeriveBytes(messageBytes, salt, 10000);
var key = pbkdf2.GetBytes(512);

Console.WriteLine("key---------:", key);
var hmacsha1 = new HMACSHA1(key);

byte[] hashmessage = hmacsha1.ComputeHash(messageBytes);
hashedvalue = Encode(hashmessage);

从Java代码和dotnet代码生成的密钥不同的问题。

我想提出建议，在dotnet中SecretKeyFactory的等效类是什么，或者我怎样才能生成与Java中相同的密钥
