Enumerate Certificates in a PFX

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.

Background. Valid indexes are less than NumCerts. Each retrieved certificate is an independent copy that can be inspected or used separately.
