vb如何加密算法

在Visual Basic（VB）中，可以使用多种加密算法来保护数据。以下是一些常用的加密方法：

1. 使用VB.NET内置的加密类

VB.NET提供了`System.Security.Cryptography`命名空间中的类，可以用来进行加密。

示例：使用AES加密

```vb

Imports System.Security.Cryptography

Imports System.Text

Module EncryptionModule

Sub Main()

Dim original As String = "Hello, World!"

Dim key As String = "ThisIsASecretKey"

Dim encrypted As String = Encrypt(original, key)

Console.WriteLine("Encrypted: " & encrypted)

Dim decrypted As String = Decrypt(encrypted, key)

Console.WriteLine("Decrypted: " & decrypted)

End Sub

Function Encrypt(ByVal plainText As String, ByVal key As String) As String

Using aes As Aes = Aes.Create()

aes.Key = Encoding.UTF8.GetBytes(key)

aes.IV = New Byte(15) {
