Demonstrates how to Authenticode sign an EXE or DLL.

* 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"
*   }
* }

loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("hashAlg","sha256")
loJson.UpdateBool("timestampToken.enabled",1)
loJson.UpdateString("timestampToken.tsaUrl","http://timestamp.digicert.com")
loJson.UpdateBool("timestampToken.requestTsaCert",1)
loJson.UpdateString("timestampToken.hashAlg","sha256")

* Load a code signing certificate..
loCert = CreateObject('Chilkat.Cert')
lnSuccess = loCert.LoadPfxFile("C:/someDir/myCodeSigningCert.pfx","pfx password")
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loJson
    RELEASE loCert
    CANCEL
ENDIF

* You can sign .exe or .dll files.
lcExePath = "C:/someOtherDir/HelloWorld.exe"

loSigner = CreateObject('Chilkat.CodeSign')

* If successful, the following call will apply the signature to the EXE (or DLL).
lnSuccess = loSigner.AddSignature(lcExePath,loCert,loJson)
IF (lnSuccess = 0) THEN
    ? loSigner.LastErrorText
    RELEASE loJson
    RELEASE loCert
    RELEASE loSigner
    CANCEL
ENDIF

? "Successfully applied the Authenticode signature."
