' 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 PEM from a file.
' If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
Dim password As String = "myPassword"
success = Await pem.LoadPemFileAsync("../myPemFiles/myPem.pem",password)
If (success <> True) Then
    Debug.WriteLine(pem.LastErrorText)
    Exit Sub
End If


' Note: If the app already has the PEM pre-loaded in a string variable, then load it 
' by calling LoadPem instead.  
Dim pemContent As String = "... the PEM contents ..."
success = Await pem.LoadPemAsync(pemContent,password)
' Check for success as before..

' Iterate over the private keys.
Dim numPrivateKeys As Integer = pem.NumPrivateKeys
Dim i As Integer = 0

While i < numPrivateKeys

    Dim privKey As Chilkat.PrivateKey = pem.GetPrivateKey(i)
    Debug.WriteLine("Private Key " & i & " is " & privKey.BitLength & " in length")


    i = i + 1
End While

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

While i < numCerts

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


    i = i + 1
End While
