Dim cert As New Chilkat.Cert

Dim success As Boolean = cert.LoadByCommonName("myCert")
If (success = False) Then
    Debug.WriteLine(cert.LastErrorText)

End If


' This example demonstrates getting the SERIALNUMBER part of the subject,
' if one such part exists in the cert's subject.
' Not too many certicates include the serial number in the Subject.
' (Chilean issued certificates for SII is one such case where the SERIALNUMBER part exists within the Subject.)

' We could also get the part by the OID.
' See https://oidref.com/2.5.4.5 for a list of OID's in the 2.5.4.* range..
' The OID for SERIALNUMBER is "2.5.4.5"
serialNum = cert.GetSubjectPart("2.5.4.5")
