Dim cert As New Chilkat.Cert

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


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


' Here's another example:
Dim cert2 As New Chilkat.Cert
success = cert2.LoadFromSmartcard("CN=yubikey rsa 1024 authentication")
If (success = False) Then
    Debug.WriteLine(cert2.LastErrorText)
    Debug.WriteLine("Certificate not loaded.")
    Exit Sub
End If


Debug.WriteLine("Found: " & cert2.SubjectDN & " serial=" & cert2.SerialNumber)
