If you have to use Symmetric Encryption in your ASP.NET project you can use the class described in the article How to create symmetric encryption utility class in ASP.NET in C#. To illustrate this you can create a page that permits you to generate a key and enter clear-text data through a text box. You can …

How to create symmetric encryption utility class in ASP.NET in VB.NET
Symmetric encryption algorithms use one key for encrypting and decrypting data. You can create a utility class that performs the encryption and decryption of sensitive data:
Imports System
Imports System.IO
Imports System.Text
Imports System.Security.Cryptography
Public NotInheritable Class SymmetricEncryptionUtility
Private Sub New()
End Sub
Private Shared _ProtectKey As Boolean
Private Shared _AlgorithmName As String
‘ You can …
How to create symmetric encryption utility class in ASP.NET in C#
Symmetric encryption algorithms use one key for encrypting and decrypting data. You can create a utility class that performs the encryption and decryption of sensitive data:
public static class SymmetricEncryptionUtility
{
private static bool _ProtectKey;
private static string _AlgorithmName;
// You can use this property to specify the name of the algorithm (DES, TripleDES, Rijndael …
Microsoft Windows supports a built-in way for storing and protecting secrets and it uses a machine key generated with the system installation for encrypting data. Only the local operating system has access to this machine key which is unique for every installation. Windows supports the DPAPI for protecting data with this key. You don’t have direct …
The CryptoStream wraps an ordinary stream and uses an ICryptoTransform. The CryptoStream have the following key advantages:
– You can use automatic encryption without worrying about the block size required by the algorithm, because the CryptoStream uses buffered access.
– CryptoStream wraps an ordinary .NET stream-derived class and you can …

The ICryptoTransform interface represents blockwise cryptographic transformation which could be an encryption, ecryption, hashing, Base64 encoding/decoding, or formatting operation. You can create an ICryptoTransform object for a given algorithm by using the:
– CreateEncryptor() method – if you want to encrypt data.
– CreateDecryptor() method – if you want to encrypt data.
The next code …

The .NET abstract encryption classes provide the following:
1. They define the basic members that encryption implementations need to support.
2. They offer some functionality through the static Create() method, which you can use to indirectly create …
Asymmetric algorithms are based on mathematical methods that require different keys for encryption and decryption. Usually the key used for encryption is called a public key and you can give it to anyone who wants to send encrypted information to you. The private key is the only key that can be used for decryption. In this case you …
