Demonstrates how to Authenticode sign an EXE or DLL.

Note: Chilkat's code signing class was added in v9.5.0.97

Dim success As Long
success = 0

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

' 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")

' Load a code signing certificate..
Dim cert As New ChilkatCert
success = cert.LoadPfxFile("C:/someDir/myCodeSigningCert.pfx","pfx password")
If (success = 0) Then
    Debug.Print cert.LastErrorText
    Exit Sub
End If

' You can sign .exe or .dll files.
Dim exePath As String
exePath = "C:/someOtherDir/HelloWorld.exe"

Dim signer As New ChilkatCodeSign

' 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
End If

Debug.Print "Successfully applied the Authenticode signature."
