VBCorLib for classic ASP

[bip]

I am trying to use VBCorLib with a classic ASP application in which I am trying to encrypt a user id and pass it to a URL string. Not much of a programmer, but am trying to adapt the VB example to pass this information to the URL. Any ideas where I could find an example? Below is the VB code. I would appreciate any help anyone might be able to give.

Private Sub Main()

dim custID
' Create a new DES key.

Dim Key As New DESCryptoServiceProvider

' Setting key

Set Key = "KeyHere"

' Pulling Customer ID from cookie to encrypt and pass to url

custID = request.cookies("customerID")

' Encrypt a string to a byte array.
Dim Buffer() As Byte
Buffer = Encrypt(custID, Key)

' Decrypt the byte array back to a string.
Dim PlainText As String
PlainText = Decrypt(Buffer, Key)

' Display the PlainText value to the console.
Console.WriteLine PlainText
Console.ReadKey
End Sub Main


' Encrypt the string.
Private Function Encrypt(ByVal PlainText As String, ByVal Key As SymmetricAlgorithm) As Byte()
Dim Buffer() As Byte
Buffer = StrConv(PlainText, vbFromUnicode)

Dim Encryptor As ICryptoTransform
Set Encryptor = Key.CreateEncryptor
Encrypt = Encryptor.TransformFinalBlock(Buffer, 0, cArray.GetLength(Buffer))
End Function


' Decrypt the byte array.
Public Function Decrypt(ByRef CypherText() As Byte, ByVal Key As SymmetricAlgorithm) As String
Dim Decryptor As ICryptoTransform
Set Decryptor = Key.CreateDecryptor

Dim Buffer() As Byte
Buffer = Decryptor.TransformFinalBlock(CypherText, 0, cArray.GetLength(CypherText))
Decrypt = StrConv(Buffer, vbUnicode)
End Function

Hello,

It is possible to use VBCorLib from within a classic ASP page. However, the example you are basing your code from is not designed to work in a web environment. You would need to write code specific to classic ASP.

Thank you for your response. I was hoping there was documentation for use within the classic ASP page.

Hello bip,

I've created a simple dll that helps use VBCorLib within a classic ASP page. In the readme.txt file I provide a simple example of how to use the helper dll with VBCorLib. This may help get you on your way to what you need to accomplish.

You can get the helper project from sourceforge.net/projects/vbcorlib.

You will have to compile it with a reference to your version of VBCorLib.
