/**
 * Add a private key to the PKCS #12 object.
 *
 * The PKCS12KeyInfo object received comes about in two
 * different scenarios:
 *
 * - The private key could be in encrypted byte[] form (e.g.
 *   when we have merely loaded a PKCS #12 file for inspection
 *   or e.g. to delete a certificate and its associated key).
 *   In this case we simply re-use this encrypted private key
 *   info byte[].
 *
 * - The private key could be a be an NSS PrivateKey handle.  In
 *   this case we must export the PrivateKey from the token to
 *   obtain the EncryptedPrivateKeyInfo.
 *
 * The common final step is to add the encrypted private key
 * data to a "Shrouded Key Bag" to the PKCS #12 object.
 * Unencrypted key material is never seen.
