將c++函式翻譯成python：sha256 hash mismatch

這與比特幣無關，但它使用了大部分比特幣程式碼庫。我想將一些 c++ 程式碼翻譯成 python，但很難得到正確的雜湊值。

這是我嘗試獲取的功能。雜湊正在做雙重 sha256

uint256 CalcKernelHash(const uint256& stakeModifier, int64_t height, int64_t coinstakeTime, const uint256& masternodeID, const Consensus::Params& params) {
       // Calculate hash
       CDataStream ss(SER_GETHASH, 0);
       ss << stakeModifier << coinstakeTime << GetMnCollateralAmount(int(height)) << masternodeID;
       std::cout << "\n--------------------------------\n";
       std::cout << "DEBUG[" << coinstakeTime << "] collateral: " << GetMnCollateralAmount(int(height)) << "\n";
       std::cout << "DEBUG[" << coinstakeTime << "] ss: " << stakeModifier.ToString() << coinstakeTime << GetMnCollateralAmount(int(height)) << masternodeID.ToString() << "\n";
       std::cout << "DEBUG[" << coinstakeTime << "] HASH: " << Hash(ss.begin(), ss.end()).ToString() << "\n";
       return Hash(ss.begin(), ss.end());
   }

在這裡它被稱為

const auto hashProofOfStake = UintToArith256(CalcKernelHash(stakeModifier, height, coinstakeTime, masternodeID, params));
   
std::cout << "DEBUG[" << coinstakeTime << "] coinstakeTime: " << coinstakeTime << "\n";
std::cout << "DEBUG[" << coinstakeTime << "] nbits: " << nBits << "\n";
std::cout << "DEBUG[" << coinstakeTime << "] hashProofOfStake: " << hashProofOfStake.ToString() << "\n";
std::cout << "DEBUG[" << coinstakeTime << "] stakeModifier: " << stakeModifier.ToString() << "\n";
std::cout << "DEBUG[" << coinstakeTime << "] masternodeId: " << masternodeID.ToString() << "\n";

我添加了一些調試語句來檢查輸出並提供參考

這是我在 python 中的試用

import binascii
import hashlib

def rotate(x):
   s2 = bytearray.fromhex(x)
   s2.reverse()
   return binascii.hexlify(s2).decode()

def padhexa(s):
   return s[2:].zfill(16)

def CalcKernelHash(stakeModifier, coinstakeTime, masternodeId):
   stakeModifier = binascii.unhexlify(stakeModifier)
   coinstakeTime = binascii.unhexlify("%x" % coinstakeTime)
   collateral = binascii.unhexlify("0%x" % 2000000000000)
   masternodeId = binascii.unhexlify(masternodeId)
   
   bin_s = stakeModifier[::-1] + coinstakeTime[::-1] + collateral[::-1] + masternodeId[::1]
   print(bin_s)
   return rotate(hashlib.sha256(hashlib.sha256(bin_s).digest()).hexdigest())



CalcKernelHash('f541f372005beeb8952f964ea638527341c3b3a6eebb0c0309e4f092bd6c1b0e', 1622528110, 'e2cfe3f576da4999ea2268224f34efdd3b0d567841d561b41b3ab67976c977d1')

當我使用調試輸出中的參數執行時，我得到

CalcKernelHash('f541f372005beeb8952f964ea638527341c3b3a6eebb0c0309e4f092bd6c1b0e', 1622528110, 'e2cfe3f576da4999ea2268224f34efdd3b0d567841d561b41b3ab67976c977d1')

'f01ba34ac7a897a1e37d61bac3a8ea6f0126c2ae883a2d75dab1f407d40aad0b'

我應該去哪裡hashProofOfStake e4b0d1b01a99d00e44d41eeb37c81d19940bf71270994fff53ea5caa1c79f663
