Load Certificate from Smart Card by Common Name

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.

' See Global Unlock Sample for sample code.

set cert = Server.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
    Response.Write "<pre>" & Server.HTMLEncode( cert.LastErrorText) & "</pre>"

    Response.End
End If

Response.Write "<pre>" & Server.HTMLEncode( "Found: " & cert.SubjectDN & " serial=" & cert.SerialNumber) & "</pre>"

' Here's another example:
set cert2 = Server.CreateObject("Chilkat.Cert")
