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.
