Ensure encryption arguments are passed to artifact (#3147)

currently, as `EncryptionArgs` are never passed to the artifact, the
artifact defaults to the auto-generated x509 cert at all times. this
patch ensures that `EncryptionArgs` are being read from the given spec,
and therefore enables custom x509 certificates for encryption. small
typo fix included, too.
