SHA256哈希計算在C++

Question

我想下面的C＃代碼轉換成C++

 SHA256 hash = SHA256.Create(); 
     hash.TransformBlock(key, 0, key.Length, null, 0); 
     for (int i = 0; i < 1000; ++i) 
     { 
      hash.TransformBlock(cipheredSHA256Hash, 0, 32, null, 0); 
     } 
     hash.TransformFinalBlock(cipheredSHA256Hash,0, 0); 

     using (RijndaelManaged rijndael = new RijndaelManaged()) 
     { 
      rijndael.Key = hash.Hash; 
      rijndael.Mode = CipherMode.ECB; 
      rijndael.Padding = PaddingMode.Zeros; 
      ICryptoTransform decryptor = rijndael.CreateDecryptor(); 

      return decryptor.TransformFinalBlock(cipheredOffSet60, 0, cipheredOffSet60.Length); 
     } 

是有上面的代碼在C++中的任何選項

嘗試在看看免費Crypto++庫。它實現了幾種加密算法，包括SHA256和AES/Rijndael。
