You have to do that yourself. The host system my app works with, credit card payment processors, create new public keys periodically that have to be used for encryption.

In my app it goes like this:
(1) Download the public key from the client via FTP
(2) Create the BlackBox objects you saw in the code snippet
(3) Build a keyring using the public key just downloaded
(4) Encrypt the file I want to send

The process is a bit involved but works reliably.
