' Unlock the Chilkat API.
' 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



Dim pem As New Chilkat.Pem

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


Dim i As Integer
Dim numCerts As Integer = pem.NumCerts

    Debug.WriteLine((("Error: Expected the .p7b to contain certificates.")))
    Exit Sub
End If


' Access each certificate and show the DN (Distinguished Name)
For i = 1 To numCerts
    Dim cert As Chilkat.Cert = pem.GetCert(i - 1)
    Debug.WriteLine(i & ": " & cert.SubjectDN)
