(Visual Basic 6.0) Code Signing using Sectigo USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a SafeNet USB token from Sectigo.

Requires Chilkat v10.0.0 or greater.

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim success As Long

' First create the following JSON to specify that SHA256 is to be used,
' and provide timestamp server information.

' {
'   "hashAlg": "sha256",
'   "timestampToken": {
'     "enabled": true,
'     "tsaUrl": "http://timestamp.digicert.com",
'     "requestTsaCert": true,
'     "hashAlg": "sha256"
'   }
' }

Dim json As New ChilkatJsonObject
success = json.UpdateString("hashAlg","sha256")
success = json.UpdateBool("timestampToken.enabled",1)
success = json.UpdateString("timestampToken.tsaUrl","http://timestamp.digicert.com")
success = json.UpdateBool("timestampToken.requestTsaCert",1)
success = json.UpdateString("timestampToken.hashAlg","sha256")

' The only difference in signing with a smartcard or USB token
' is that the cert is loaded from a smartcard or USB token, instead of a PFX or from elsewhere
' such as from the Windows certificate store.
Dim cert As New ChilkatCert

' Use your USB token PIN (user password).
' It will be a string similar to this:  j6X54nB7-jlp5Cr2
cert.SmartCardPin = "j6X54nB7-jlp5Cr2"

' Load the certificate based on the serial number.
' *** Use your certificate's serial number.
success = cert.LoadFromSmartcard("serial=3FF5B69109BFD4046C92CC0D18EE23C2")
If (success = 0) Then
    Debug.Print cert.LastErrorText
    Exit Sub
End If

' Note: If the above fails, then use the SafeNet Authentication Client Tools
' to login to your token using your token password.
' You don't want too many failed logins, otherwise you'll lock the token.
' A successful login will reset number of failed logins back to 0.

' Note: This is to sign Microsoft Windows executables or DLLs
' You can sign .exe or .dll files.
Dim exePath As String
exePath = "C:/someDirectory/HelloWorld.exe"

' If successful, the following call will apply the signature to the EXE (or DLL).
success = signer.AddSignature(exePath,cert,json)
If (success = 0) Then
    Debug.Print signer.LastErrorText
    Exit Sub

Debug.Print "Successfully applied the Authenticode signature."
