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.

* 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")

* 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.
loCert = CreateObject('Chilkat.Cert')

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

* Load the certificate based on the serial number.
* *** Use your certificate's serial number.
lnSuccess = loCert.LoadFromSmartcard("serial=3FF5B69109BFD4046C92CC0D18EE23C2")
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loJson
    RELEASE loCert
    CANCEL
ENDIF

* 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.
lcExePath = "C:/someDirectory/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."
