Password Protection: Example For Win32(64) Apps

It is easy to set protection in your applications.

Set protection with a few simple steps:
Step 1: Set ProtectKit code in your application.
Step 2: Set protection information using the "Set Password Protection Tool".
Step 3: Digitally sign your application if desired.
Step 4: Deploy Application.
Step 5: Generate a password and send it to the user.

 

Win32 (Win64) Example: (in Visual Basic)

 Step 1:   Set ProtectKit code in your application code

Initializing the ProtectKit3.5 in the Form Load event:

Private Sub Form_Load()
     Dim LockWord As String * 9
     Dim ChkLockword As String
     Dim LockwordLen As Long
     .
     ret = PK3Initialize("Project1.exe", "ProInfo.dll")
     If ret <> 0 Then
          If ret = 1 Then Msg= "Unable to run application."
          If ret = 2 Then Msg= "Unable to load protection information file."
          If ret = 3 Then Msg= "The lockword is incorrect."
          .
          End
     End If

     LockwordLen = PK3GetLockword(LockWord)
     ChkLockword = "Ab" & "cd" & "ef" & "gH"
     If LockwordLen <> 8 Or ChkLockword <> Left(Lockword, LockwordLen) Then
          End
     End If
End Sub

Retrieve the PC's Hardware Signature (PcID)

Private Sub Command1_Click()
Dim str As String * 65
Dim strLen As Long
...
ret = PK3QueryPcID(str, strLen)
Text2.Text = str
...
End Sub

Set the Password

Private Sub Command2_Click()
ret = PK3SetPassword(Text1.Text)
End Sub

Check Protection Status

Private Sub Command3_Click()
ret = PK3QueryProtect()
If ret = 0 Then Msg = "Application is unlocked."
If ret = 1 Then Msg = "Application is locked."
If ret = 2 Then Msg = "Exceeded allowable number of uses."
    .
End Sub

 

 Step 2:   Set protection information

Use the Set Password Protection tool to set protection information into your application:

This tool writes protection information into a "protection information file" and also embeds the same information into your compiled application.

 

 

 Step 3:   Digital signature

If you are digitally signing your application, do that at this step. If you are not digitally signing your application, proceed to Step 4.

 

 Step 4:   Deploy your application

Deploy your application and all its associated files to the target machine.

 

 Step 5:   Generate the password and notify the user

The Password Generator

The ProtectKit3.5 provides several ways to generate passwords. The runtime Password Generator (EXE) allows you to enter a lockword and a PcID and generate a password manually. For example, using the lockword from Step 2 and the PcID retrieved from the user's PC, you can generate a password, which you send to the enduser so that they can unlock the application.

Password Generator EXE

Password Generator OCX and DLL

These files provide the password generating functions in a useful API. This API allows you to generate passwords programmatically from the lockword and retrieved PcID and to send the passwords to your users.

Below is an example of a web application that uses VBScript code to to generate a password.

Set objCOM = Server.CreateObject("Pr3PassGen.PassGen")
objCOM.LockWord = varLockword
objCOM.PCID = varPCID
objCOM.PasswordType = varType
varUnlockword = objCOM.PS3GetPassword
Set objCOM = nothing

Here is Visual Basic code that uses the EMail API

ret = PS3SendMail("msv.newtone.co.jp", "info@newtone.co.jp", _
"NEWTONE", "paul@company.com", "Users", _
"PassWord Information", "Below is the password needed to unlock....")
