Как я...решаю шифрование с помощью AES 256 с ключом C# к java

---

Сценарий, подобный API, разработанный на Java и должен потреблять в asp.net с#. Проблема заключается в шифровании и дешифровании полезной нагрузки. Алгоритм AES-256 , генерируемый зашифрованным текстом в c#, не совпадает с Java. Пожалуйста, помогите. заранее спасибо.

Что я уже пробовал:

JAVA CODE : 
public static void main(String args[]) 
    {
        MyClass obj = new MyClass();

        String mdString = obj.generateAESEncryption("dfgfrhdfgfrhdfgfrhdfgfrhdfgfrhil", "1");

        System.out.println(" AES 256 Encrypted Key : " + mdString);
    }

    public String generateAESEncryption(String sercretKey, String message) 
    {

        String base64EncryptedString = "";

        MessageDigest md = null;
        try {

            md = MessageDigest.getInstance("SHA-256");


            byte[] digestOfPassword = md.digest(sercretKey.getBytes(StandardCharsets.UTF_8));
            
            System.out.println(" Message Digest Byte[] String : " + digestOfPassword);
            

            byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);

            byte[] iv = Arrays.copyOf(digestOfPassword, 16);
            
            System.out.println(" keyBytes Byte[] String : " + digestOfPassword);
            System.out.println(" iv Byte[] String : " + digestOfPassword);

            SecretKey key = new SecretKeySpec(keyBytes, "AES");

            Cipher cipher = null;
            try {
                    cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");


                    IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);

                    try 
                    {
                        cipher.init(Cipher.ENCRYPT_MODE, key, ivParameterSpec);
                    } 
                    catch (InvalidAlgorithmParameterException | InvalidKeyException e) 
                    {
                        e.printStackTrace();
                    }

                    byte[] plainTextBytes = message.getBytes(StandardCharsets.UTF_8);
                    
                    System.out.println(" plainTextBytes Byte[] String : " + digestOfPassword);

                    byte[] buf = new byte[0];
                    try 
                    {
                        buf = cipher.doFinal(plainTextBytes);
                    } 
                    catch (BadPaddingException e) 
                    {
                        e.printStackTrace();
                    } 
                    catch (IllegalBlockSizeException e) 
                    {
                        e.printStackTrace();
                    }

                    //byte[] encryptedByteValue = new Base64().encode(buf);
                    byte[] encryptedByteValue = Base64.getEncoder().encode(buf);

                    //String encryptedValue = encryptedByteValue.toString();
                    base64EncryptedString = new String(encryptedByteValue, StandardCharsets.UTF_8);

                    //Logger.debug("AES : ", "EncryptedValue : " + base64EncryptedString);

                } 
                catch (NoSuchPaddingException e) 
                {
                    e.printStackTrace();
                }
        } 
        catch (NoSuchAlgorithmException e) 
        {
            e.printStackTrace();
        }

        return base64EncryptedString;
    }
}

C# Code : 

        private static string Encrypt_2(string PlainText, String key)
        {
            HashAlgorithm Hasher = new SHA256CryptoServiceProvider();
            byte[] strBytes = Encoding.UTF8.GetBytes(key);
            byte[] passBytes = Hasher.ComputeHash(strBytes);

            RijndaelManaged aes = new RijndaelManaged();
            aes.BlockSize = 128;
            aes.KeySize = 256;

            // It is equal in java 
            /// Cipher _Cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");    
            aes.Mode = CipherMode.CBC;
            aes.Padding = PaddingMode.PKCS7;

            byte[] keyArr = Convert.FromBase64String(key);
            byte[] KeyArrBytes32Value = new byte[24];
            Array.Copy(passBytes, KeyArrBytes32Value, 16);

            // Initialization vector.   
            // It could be any value or generated using a random number generator.
            byte[] ivArr = { 1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1, 7, 7, 7, 7 };
            byte[] IVBytes16Value = new byte[16];
            Array.Copy(ivArr, IVBytes16Value, 16);

            aes.Key = KeyArrBytes32Value;
            aes.IV = IVBytes16Value;

            ICryptoTransform encrypto = aes.CreateEncryptor();

            byte[] plainTextByte = ASCIIEncoding.UTF8.GetBytes(PlainText);
            byte[] CipherText = encrypto.TransformFinalBlock(plainTextByte, 0, plainTextByte.Length);
            return Convert.ToBase64String(CipherText);

        }
