Yeah, that means it can't successfully resolve the data decryption key,
and since you're using an encrypted key transported via an EncryptedKey,
ultimately it means it can't decrypt the EncryptedKey.

Remember that you decrypt with the recipient's private key.  So you need
to also set the PrivateKey object on the Credential above with which you
are going to encrypt (the one that gets resolved and used by the Decrypter)


Offhand, everything else looks right, as far as I can tell.
