SHA256 Hash calculation in C++

I am trying to convert following C# code into 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);
        }

is there any option for above code in C++

Try having a look at the free Crypto++ library. It implements several cryptographic algorithms, including SHA256 and AES/Rijndael.

Check the following discussions for examples on how to create SHA256 hashes and decrypt AES:
