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 manage secret keys in ASP.NET

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 .NET CryptoStream class in VB.NET

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 …
