Load P7B and Iterate Certificates

See more PEM Examples

Demonstrates how to load a .p7b containing one or more certificates access each of them. VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

success = False

' 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 = pem.LoadP7bFile("../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
