Add Powerful Encryption To Your Visual Basic Programs

[dglienna]

Note: This doesn't run under Windows 2000 (with up to date service packs)

I compiled the project, and it didn't run. It works fine under XP Home.

Just found this, and it DOES work on both platforms. I don't know why.

Option Explicit 

Dim sSecretData
sSecretData = "Here is some very secret data." 

' Build up the key
Dim wshNetwork, sComputerName
Set wshNetwork = WScript.CreateObject("WScript.Network") 
sComputerName = wshNetwork.ComputerName

Dim capEData
Set capEData = CreateObject("CAPICOM.EncryptedData")

capEData.Algorithm = 3 'Use 3DES
capEData.SetSecret sComputerName 
capEData.Content = sSecretData

Dim sCipherText
sCipherText = capEData.Encrypt

capEData.Algorithm = 3
capEData.SetSecret sComputerName 
capEData.Decrypt sCipherText

Dim sPlainText
sPlainText = capEData.Content 

MsgBox "Original data: " & sSecretData & chr(13) _ 
  & "Encrypted data: " & sCipherText & chr(13) _ 
  & "Recoverd data: " & sPlainText
