How to use parameterized SQL queries to protect ASP.NET web application from SQL injection in C#
SQL injection is used as a way to gain control over a web application by simply injecting some specially created SQL query via a parameter. This kind of the worst attack for a web application is caused by improper handling of string concatenation. The next code lines illustrate a typical problem related to SQL injection. For …
If you have to use asymmetric encryption in your ASP.NET project you can use the class described in the article How to create asymmetric encryption utility class in ASP.NET in VB.NET. 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 output the …

How to create asymmetric encryption utility class in ASP.NET in VB.NET
The major difference between symmetric and asymmetric algorithms is key management. Symmetric algorithms have one key, and asymmetric algorithms have two keys: public key for encrypting data and private key for decrypting data. The public key can be available to everyone who wants to encrypt data, the private key should be available only to those decrypting …

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 …
