(Unicode C) Get Certificates from .p12 / .pfx

A PKCS12 (.p12 / .pfx) is a container for holding a certificate, its private key, and the certs in the chain of authentication up to and possibly including the root CA cert. A .p12 is not required to contain certain things. It will contain whatever the creator of the .p12 decided to include. It's possible to contain just a private key, just a cert, many certs without private keys, or many certs with many private keys. Usually, a .p12 contains one certificate, its associated private key, and certificates in the chain of authentication.
