CryptoOperations

anoncrypt - Guarantees confidentiality and integrity without revealing the identity of the sender.

authcrypt - Guarantees confidentiality and integrity. Also proves the identity of the sender – but in a way that only the recipient can verify. This is the default wrapping choice, and SHOULD be used unless a different goal is clearly identified. By design, this combination and all other combinations that use encryption in their outermost layer share an identical IANA media type, because only the recipient should care about the difference.
