الگوریتم رمزنگاری قابل بازگشت (Rijndael)

کد:
string SecureDataAlg(string StrInp,byte[] key,byte[] iv)



        {



            byte[] input = Encoding.UTF8.GetBytes(StrInp);



 



            CryptoStream cryptoStream = null;



            RijndaelManaged rijndael = null;



            ICryptoTransform rijndaelTransform = null;



            MemoryStream memStream = null;



 



            rijndael = new RijndaelManaged();



            rijndael.Key = key;



            rijndael.IV = iv;



 



            rijndaelTransform = rijndael.CreateEncryptor();



 



            memStream = new MemoryStream();



            cryptoStream = new CryptoStream(memStream, rijndaelTransform, CryptoStreamMode.Write);



 



            cryptoStream.Write(input, 0, input.Length);



 



            cryptoStream.FlushFinalBlock();



            byte[] str = memStream.ToArray();



 



            return Convert.ToBase64String(str);
