asp.net - Avoid "==" in Encrypting string -


Below is my code every time when I encrypt the string, it is giving the string "==" at the end is.

How can I avoid it 

  encrypt the private function (as a clear string) String dim EncryptionKey string = "MAKV2SPBNI99212" as the dim clearBytes byte In the form of () = Encoding.Unicode.GetBytes (Clear) using as encryptor AES = AES. H49, & amp;, H76, & amp; H61, & amp; H6E, & amp; H20, & amp; H4D, _ & amp; H65, & amp; (H64, & H76, & H65, & amp; H64, & amp; H65, _ & H76} to make slow pdb new Rfc2898DeriveBytes (EncryptionKey, New byte () & amp; ) Encryptor.Key = pdb.GetBytes (32) encryptor.IV = pdb.GetBytes (16) New MemoryStream () Using MS as the new CryptoStream (MS, encryptor.CreateEncryptor (), CryptoStreamMode.Write) Cs.Write (clearBytes, 0, clearBytes.Length) cs.Close () use the other end from the end clear = Convert.ToBase64String (ms.ToArray ()) use the clear text as the end use    
 
 
 The result is just this Ngit is that the length of the input byte array is not a 3, and required to decode the correct string. It's not a matter of concern, and this is not an indication that there is anything wrong with your encryption algorithm.  
 You really need to stop it, make sure the byte array passes you to  ToBase64String , possibly not array padding with the zeros (but then you do not have string decoding Do not want to be able to close those zero bars) that is a multi-length of 3 by that.

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
