Find a PFX Certificate by localKeyId

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert object.

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. The encoding argument names the binary representation of the id, such as decimal, base64, or hex. The localKeyId links a certificate to its corresponding private key within the container.
