Loads a digital certificate from a base64 encoded DER X.509 Certificate (.cer, .crt) and fetches information about the cert. VB.NET

Dim success As Boolean = False

Dim cert As New Chilkat.Cert

' LoadFromFile will load virtually any certificate format file.
' It will auto-recognize the format and load appropiately.
' A base64-encoded DER X.509 certificate file
' contains the binary DER in base64 encoded form.
' Therefore, it is a text file that will begin like this:
' -----BEGIN CERTIFICATE-----
' MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
' EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
' ...

success = cert.LoadFromFile("/Users/chilkat/testData/cer/chilkat_base64.cer")
If (success <> True) Then
    Debug.WriteLine(cert.LastErrorText)
    Exit Sub
End If


' DN = "Distinguished Name"
Debug.WriteLine("SubjectDN:" & cert.SubjectDN)

Debug.WriteLine("Common Name:" & cert.SubjectCN)
Debug.WriteLine("Issuer Common Name:" & cert.IssuerCN)

Debug.WriteLine("Serial Number:" & cert.SerialNumber)
