数据损坏 AES C#

Question

请注意，我知道这是重复的，但答案对我没有帮助。

所以我试图建立 AES 和 RSA 加密连接，这样我就可以加密非常大的东西，但是在使用 AES 解密某些东西时，我在数据的开头遇到了垃圾，这是我的代码（是的，我尝试过硬编码） IV）：

                RSA rsa = RSA.Create();
                rsa.KeySize = 1024;
                Aes aes = Aes.Create();
                aes.IV = Encoding.UTF8.GetBytes("1234567890123456");
                byte[] sendBytes = null;
                byte[] buffer = new byte[1024];
                TcpClient client = new TcpClient();
                client.Connect(new IPEndPoint(IPAddress.Loopback, 900));
                NetworkStream ns = client.GetStream();
                ns.Write(Encoding.UTF8.GetBytes(rsa.ToXmlString(false) + "$"), 0, (rsa.ToXmlString(false) + "$").Length);
                ns.Read(buffer, 0, buffer.Length);
                MessageBox.Show(Encoding.UTF8.GetString(buffer));
                rsa.FromXmlString(Encoding.UTF8.GetString(buffer).Split('$')[0]);
                ns.Write(Encoding.UTF8.GetBytes(Convert.ToBase64String(rsa.Encrypt(aes.Key, RSAEncryptionPadding.Pkcs1)) + "$"), 0, (Convert.ToBase64String(rsa.Encrypt(aes.Key, RSAEncryptionPadding.Pkcs1)) + "$").Length);
                MessageBox.Show(Convert.ToBase64String(rsa.Encrypt(aes.Key, RSAEncryptionPadding.Pkcs1)));
                ICryptoTransform encrypt = aes.CreateEncryptor();
                sendBytes = Encoding.UTF8.GetBytes("*" + Convert.ToBase64String(encrypt.TransformFinalBlock(Encoding.UTF8.GetBytes(authResult.AccessToken), 0, authResult.AccessToken.Length)) + "|" + Convert.ToBase64String(aes.IV) + "$");
                ns.Write(sendBytes, 0, ("*" + Convert.ToBase64String(encrypt.TransformFinalBlock(Encoding.UTF8.GetBytes(authResult.AccessToken), 0, authResult.AccessToken.Length)) + "|" + Convert.ToBase64String(aes.IV) + "$").Length);
                sendBytes = Encoding.UTF8.GetBytes(Convert.ToBase64String(encrypt.TransformFinalBlock(Encoding.UTF8.GetBytes(authResult.Account.Username), 0, authResult.Account.Username.Length)) + "$");
                ns.Write(sendBytes, 0, (Convert.ToBase64String(encrypt.TransformFinalBlock(Encoding.UTF8.GetBytes(authResult.Account.Username), 0, authResult.Account.Username.Length)) + "$").Length);
                ns.Dispose();
                client.Close();

这是服务器：

                    NetworkStream networkStream = clientSocket.GetStream();
                    networkStream.Read(bytesFrom);
                    string dataFromClient = Encoding.UTF8.GetString(bytesFrom).Split("$")[0];
                    networkStream.Write(Encoding.UTF8.GetBytes(rsa.ToXmlString(false) + "$"));
                    rsa.FromXmlString(dataFromClient.Split("$")[0]);
                    int waste;
                    rsa.ImportRSAPrivateKey(key, out waste);
                    Console.WriteLine(rsa.KeySize.ToString());
                    networkStream.Read(bytesFrom);
                    Console.WriteLine(Encoding.UTF8.GetString(bytesFrom));
                    aes.Key = rsa.Decrypt(Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("$")[0]), RSAEncryptionPadding.Pkcs1);
                    ICryptoTransform decrypt = aes.CreateDecryptor();
                    networkStream.Read(bytesFrom);
                    aes.IV = Encoding.UTF8.GetBytes("1234567890123456");
                    dataFromClient = Encoding.UTF8.GetString(decrypt.TransformFinalBlock(Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("|")[0].Split("*")[1]), 0, Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("|")[0].Split("*")[1]).Length));
                    Console.WriteLine(Encoding.UTF8.GetString(decrypt.TransformFinalBlock(Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("|")[0].Split("*")[1]), 0, Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("|")[0].Split("*")[1]).Length)));
                    string info = await GetHttpContentWithToken("https://graph.microsoft.com/v1.0/me", dataFromClient);
                    Console.WriteLine(info);
                    Root a = JsonConvert.DeserializeObject<Root>(info);
                    networkStream.Read(bytesFrom);
                    dataFromClient = Encoding.UTF8.GetString(decrypt.TransformFinalBlock(Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("$")[0]), 0, Convert.FromBase64String(Encoding.UTF8.GetString(bytesFrom).Split("$")[0]).Length));

（是的，我正在搞乱微软帐户，你可以忽略除了密钥交换和 AES 解密代码之外的所有内容。）

仔细观察后，我意识到我在 IV 之前创建了解密器，对此感到抱歉。
