Encryption of data is mandatory followed in some
networks or in saving passwords to the database. So encrypting the data and
decrypting the already encrypted code has been logged here.
Here there is two functions Encrypt and Decrypt to
convert the data, find the below code for reference.
ASP.Net
Code
<html>
<head runat="server">
<title>Encrypt and Decrypt: fourthbottle</title>

<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
