(VBScript) Load Certificate from Smart Card by Common Name

See more Certificates Examples

This example requires Chilkat v9.5.0.87 or greater. It uses a Windows-only function named LoadFromSmartcard.

This example loads a certificate specified by its subject common name (CN part of the Subject). The LoadFromSmartcard method will examine the connected smart cards and USB tokens and will find and load the certificate having the specified CN.

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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Cert")
set cert = CreateObject("Chilkat.Cert")

' If you know the smart card PIN, set it prior to loading from the smartcard/USB token.
cert.SmartCardPin = "12345678"

' To load the certificate specified by CN, pass the string "CN=<subjectCN>".  For example:
success = cert.LoadFromSmartcard("CN=Ch application signature (8c9be8e0-5544-4cd0-9062-290fbff353a7)")
If (success = 0) Then
    outFile.WriteLine(cert.LastErrorText)
    outFile.WriteLine("Certificate not loaded.")

End If

outFile.WriteLine("Found: " & cert.SubjectDN & " serial=" & cert.SerialNumber)

' Here's another example:
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Cert")
set cert2 = CreateObject("Chilkat.Cert")
success = cert2.LoadFromSmartcard("CN=yubikey rsa 1024 authentication")
If (success = 0) Then
    outFile.WriteLine(cert2.LastErrorText)
    outFile.WriteLine("Certificate not loaded.")
    WScript.Quit
End If
