Add a Private Key and Certificate Chain to a PFX

See more PFX/P12 Examples

Demonstrates Pfx.AddPrivateKey, which adds a private key together with its certificate chain to the PFX 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 chain must contain at least one certificate; the certificate at index 0 is treated as the leaf. The chain is built here with Cert.BuildCertChain.
