python中的SHA512编码

Question

我需要关于python中sha512编码的帮助。我正在尝试编写一段python代码，它应该与c代码保持一致

这里是C#中的方法

public string GenerateSHA512Hash(string data, sting salt) {
  data = data.Replace(" ", string.Empty).Replace("\n", string.Empty).Replace("\t", string.Empty).Replace("\r", string.Empty).Trim();

  data = data + salt;

  byte[] HashedBytes = Encoding.UTF8.GetBytes(data);

  using(SHA512Managed hash = new SHA512Managed()) {
    for (int j = 0; j < 2; j++) {
      HashedBytes = hash.ComputeHash(HashedBytes);
      var text = HashedBytes.ToBase16();
    }
  }

  return HashedBytes.ToBase16();
}

我在python中获得了以下内容

import hashlib

def HashPAN(pan: str, salt: str):
    data: str = pan + salt
    data = data.replace(" ", "").replace("\n", "").replace("\t", "").replace("\r", "")
    data_bytes = data.encode("utf-8")

    hasher = hashlib.sha512()

    # First Iteration
    hasher.update(data_bytes)
    hashed = hasher.digest()
    h = hasher.hexdigest().upper()

    # Second Iteration
    hasher.update(hashed)
    hashed = hasher.digest()
    h = hasher.hexdigest().upper()

    return hashed

在python中，标记为#First Iteration的部分的结果与C#代码（h=text）中循环中第一次的结果相匹配

但是，python中的第二次与c#中的第二次不匹配。有人能帮忙吗

我知道了如何在python中实现这一点

def HashPAN(pan: str, salt: str):
    data: str = pan + salt
    data = data.replace(" ", "").replace("\n", "").replace("\t", "").replace("\r", "")
    data_bytes = data.encode("utf-8")
    hashed_text: str

    for i in range(2):
        hasher = hashlib.sha512()
        hasher.update(data_bytes)
        data_bytes = hasher.digest()
        hashed_text = hasher.hexdigest()

    return hashed_text.upper()
