The following code example opens the current user's personal certificate store, allows the user to select a certificate, and then writes certificate and certificate chain information to the console. The output depends on the certificate you select.
'Output chain element information. Console.WriteLine("Chain Element Information") Console.WriteLine("Number of chain elements: {0}", ch.ChainElements.Count) Console.WriteLine("Chain elements synchronized? {0} {1}", ch.ChainElements.IsSynchronized, Environment.NewLine) Dim element As X509ChainElement For Each element In ch.ChainElements Console.WriteLine("Element issuer name: {0}", element.Certificate.Issuer) Console.WriteLine("Element certificate valid until: {0}", element.Certificate.NotAfter) Console.WriteLine("Element certificate is valid: {0}", element.Certificate.Verify()) Console.WriteLine("Element error status length: {0}", element.ChainElementStatus.Length) Console.WriteLine("Element information: {0}", element.Information) Console.WriteLine("Number of element extensions: {0}{1}", element.Certificate.Extensions.Count, Environment.NewLine) If ch.ChainStatus.Length > 1 Then Dim index As Integer For index = 0 To element.ChainElementStatus.Length Console.WriteLine(element.ChainElementStatus(index).Status) Console.WriteLine(element.ChainElementStatus(index).StatusInformation) Next index End If Next element store.Close()
