' 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 ChilkatGlobal
Dim success As Long
success = chilkatGlob.UnlockBundle("Anything for 30-day trial.")
If (success <> 1) Then
    Debug.Print chilkatGlob.LastErrorText

' 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 ChilkatPem

' Load the .p7b from a file.
success = pem.LoadP7bFile("../myCertFiles/myP7b.p7b")
If (success <> 1) Then

' 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.
