Enumerate Certificates in a PFX

See more PFX/P12 Examples

Demonstrates Pfx.CertAt, which copies the certificate at a zero-based index into a Cert object. The example enumerates all certificates in the PFX.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Dim success As Boolean = False

Dim pfx As New Chilkat.Pfx

'  The file path is relative to the application's current working directory.  An absolute path
'  may also be used.  Supply the path appropriate to your own environment.
'  The PFX password should come from a secure source rather than being hard-coded.
Dim password As String = "myPfxPassword"
success = pfx.LoadPfxFile("qa_data/identity.pfx",password)
If (success = False) Then
    Debug.WriteLine(pfx.LastErrorText)
    Exit Sub
End If


'  Enumerate the certificates in the PFX by zero-based index.  Valid indexes are less than NumCerts.
'  The certificate at index 0 is typically the certificate that has a private key, and the remaining
'  certificates are the others in its certificate chain.
Dim numCerts As Integer = pfx.NumCerts
Dim cert As New Chilkat.Cert
Dim i As Integer
For i = 0 To numCerts - 1
    success = pfx.CertAt(i,cert)
    If (success = False) Then
        Debug.WriteLine(pfx.LastErrorText)
        Exit Sub
    End If

    Debug.WriteLine("Certificate " & i & ": " & cert.SubjectCN)
