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.

Dim success As Boolean = False

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

Dim cert As ChilkatCert
cert.Initialize("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 = False Then
    Log(cert.LastErrorText)
    Log("Certificate not loaded.")
    Return
End If


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

'  Here's another example:
Dim cert2 As ChilkatCert
cert2.Initialize("cert2")
success = cert2.LoadFromSmartcard("CN=yubikey rsa 1024 authentication")
If success = False Then
    Log(cert2.LastErrorText)
    Log("Certificate not loaded.")
    Return
End If


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