' Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
' by calling UnlockBundle.  It requires a Bundle unlock code.
Dim chilkatGlob As New Chilkat.Global
Dim success As Boolean = chilkatGlob.UnlockBundle("Anything for 30-day trial.")
If (success <> True) Then
    Debug.WriteLine(chilkatGlob.LastErrorText)
    Exit Sub
End If


' The Chilkat PEM class was introduced in v9.5.0.49.  
' It requires the bundle to be unlocked, as shown above.
Dim pem As New Chilkat.Pem

' Load the .p7b from a file.
success = Await pem.LoadP7bFileAsync("../myCertFiles/myP7b.p7b")
If (success <> True) Then
    Debug.WriteLine(pem.LastErrorText)
    Exit Sub
End If


' Note: If the app already has the p7b loaded in memory, the LoadP7b method
' may be called instead.  (see the online reference documentation)


' Iterate over the certificates.
Dim numCerts As Integer = pem.NumCerts
Dim i As Integer = 0

While i < numCerts

    Dim cert As Chilkat.Cert = pem.GetCert(i)
    Debug.WriteLine("Certificate " & i & " : " & cert.SubjectDN)


    i = i + 1
End While
