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"
'    }
'  }

Dim json As ChilkatJsonObject
json.Initialize
json.UpdateString("hashAlg", "sha256")
json.UpdateBool("timestampToken.enabled", True)
json.UpdateString("timestampToken.tsaUrl", "http://timestamp.digicert.com")

'  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 ChilkatCert
cert.Initialize("cert")

'  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 = False Then
    Log(cert.LastErrorText)
    Return
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 = "C:/someDirectory/HelloWorld.exe"

'  If successful, the following call will apply the signature to the EXE (or DLL).
