Sockets ASCII & Base64 Encryption Problems?

I'm building a typical TCP Socket Server / Client in the usual way. Now I have a problem after encrypting the data. Both Client and Server have identical myCrypto classes and password123. I don't receive errors performing the Encryption on the Client, just during Decryption on the Server...

[Client]
publice void SendData(string message)
{
Object oData = myCrypto.Encrypt(message, "password123");
byte[] byteData = System.Text.Encoding.ASCII.GetBytes(oData.ToString());
}

[Server]
public void DataRcvd(IAsyncResult aResult)
{
string dataEncrypted = Encoding.ASCII.GetString(skt.byteBuffer, 0, skt.byteBuffer.Length);
string dataDecrypted = myCrypto.Decrypt(dataEncrypted, "password123");
}

does (Server) string dataEncrypted Equal (Client) oData.ToString() ?

I'm check that out now...

Go figure, for what ever reason, loading the received data into a textbox somehow fixes the problem, although I don't want to use a textbox because the Win-App is just a testing project to eventually build a Win-Service later....
public void DataRcvd(IAsyncResult aResult)
{
string dataEncrypted = Encoding.ASCII.GetString(skt.byteBuffer, 0, skt.byteBuffer.Length);

textBox_ReceivedMsg.Text = dataEncrypted;

string dataDECRYTPED = myCrypto.Decrypt(txtReceivedMsg.Text, "password123");

textBox_Decrypted.Text = dataDECRYTPED;
}

Maybe the line below will do it

string dataEncrypted = Convert.ToString (Encoding.ASCII.GetString(skt.byteBuffer, 0, skt.byteBuffer.Length));  
 
or
 
string dataEncrypted = Encoding.ASCII.GetString(skt.byteBuffer, 0, skt.byteBuffer.Length).ToString ();

No, both code suggestions failed because I now need to convert to base64, which I did, then I receive a padding error....
I guess I need to investigate how a TextBox converts input data.
