Get the Server Certificate from a TLS Connection

See more Socket/SSL/TLS Examples

Demonstrates Socket.GetServerCert, which copies the certificate presented by the remote TLS server into a Cert object for inspection.

Dim success As Boolean = False

Dim socket As New Chilkat.Socket

'  Connect to the server using TLS.
Dim bTls As Boolean = True
Dim maxWaitMs As Integer = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If


'  Copy the certificate presented by the remote TLS server, then inspect it.  This can be used to
'  validate the server's identity.
Dim cert As New Chilkat.Cert
success = socket.GetServerCert(cert)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

Debug.WriteLine("Server certificate subject: " & cert.SubjectCN)
Debug.WriteLine("Issued by: " & cert.IssuerCN)
