我无法使用c#中的Rijndael方法正确解密文件中的加密数据？

我有两种使用加密和解密的方法，我做的是读取文件数据加密并用加密数据修改文件，此操作正确完成，但当我解密加密数据时，如果我返回奇怪字符，则不会返回非原始值： 这些是功能：

public void EncryptFile(string[] conexion)
        {

            var mydocpath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);


            var inputFile = mydocpath + @"\ProjectCONFIG.sigc";

            const string password = @"*PROJECT-CONFIG-FILE-ENCRYPTED-2016*"; // Your Key Here

            var cryptFile = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
            var fsEncrypt = new FileStream(inputFile, FileMode.Create);

            var rmCrypto = new RijndaelManaged();

            Rfc2898DeriveBytes pwdGen = new Rfc2898DeriveBytes(password, 10000);
            rmCrypto.BlockSize = 256;

            byte[] key = pwdGen.GetBytes(rmCrypto.KeySize / 8);   //This will generate a 256 bits key
            byte[] iv = pwdGen.GetBytes(rmCrypto.BlockSize / 8);  //This will generate a 256 bits IV

            var cs = new CryptoStream(fsEncrypt, rmCrypto.CreateEncryptor(key, iv), CryptoStreamMode.Write);
            StreamWriter streamWriter = new StreamWriter(cs);
            streamWriter.WriteLine(conexion);

            streamWriter.Close();
            cs.Close();
            fsEncrypt.Close();
        }

        public string DecryptFile(string inputFile)
        {

            const string password = @"*PROJECT-CONFIG-FILE-ENCRYPTED-2016*"; // Your Key Here

            var cryptFile = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
            var fsEncrypt = new FileStream(inputFile, FileMode.Create);

            var rmCrypto = new RijndaelManaged();

            Rfc2898DeriveBytes pwdGen = new Rfc2898DeriveBytes(password, 10000);
            rmCrypto.BlockSize = 256;

            byte[] key = pwdGen.GetBytes(rmCrypto.KeySize / 8);   //This will generate a 256 bits key
            byte[] iv = pwdGen.GetBytes(rmCrypto.BlockSize / 8);  //This will generate a 256 bits IV

            var cs = new CryptoStream(fsEncrypt, rmCrypto.CreateEncryptor(key, iv), CryptoStreamMode.Read);

            StreamReader streamReader = new StreamReader(cs);
            string conexion = streamReader.ReadLine();


            streamReader.Close();
            cs.Close();
            fsEncrypt.Close();

            return conexion;
        }

任何建议……

@Artjom B.他意识到我在解密功能中犯了一个错误，该功能将显示：

 public string DecryptFile(string inputFile)
        {

            const string password = @"*PROJECT-CONFIG-FILE-ENCRYPTED-2016*"; // Your Key Here

            var cryptFile = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
            var fsEncrypt = new FileStream(inputFile, FileMode.Create);

            var rmCrypto = new RijndaelManaged();

            Rfc2898DeriveBytes pwdGen = new Rfc2898DeriveBytes(password, 10000);
            rmCrypto.BlockSize = 256;

            byte[] key = pwdGen.GetBytes(rmCrypto.KeySize / 8);   //This will generate a 256 bits key
            byte[] iv = pwdGen.GetBytes(rmCrypto.BlockSize / 8);  //This will generate a 256 bits IV

// The mistake is that he was calling the CreateEncryptor function ()
                var cs = new CryptoStream(fsEncrypt, rmCrypto.CreateDecryptor(key, iv), CryptoStreamMode.Read);

            StreamReader streamReader = new StreamReader(cs);
            string conexion = streamReader.ReadLine();


            streamReader.Close();
            cs.Close();
            fsEncrypt.Close();

            return conexion;
        }

您正在为decryption@Plutonix如果没有太多不适，请按原样给我写一个答案。您在解密过程中使用的是

rmCrypto.CreateEncryptor

。它应该是一个

rmCrypto.CreateDecryptor

。这是一个输入错误问题，应该关闭。@Artjom B。错误由加密两次的函数组成，我的错误是检查不好……谢谢
