This is a variant of AuthCredential that carries two UUIDs, intended to be a user's ACI and PNI. Why? Because when you've been invited to a group, you may have been invited by your ACI or by your PNI, or by both, and it's easier for clients to treat all those states the same by having a credential that covers both identities. The downside is that it's larger (both the data, obviously, but also the zkgroup proof of validity, unsurprisingly). AnyAuthCredentialPresentation gains a 'get_pni_ciphertext' method, which will return `None` for the existing presentations and `Some(encrypted_pni)` for the new credential. Having a separate credential type but a common presentation type makes it easier for the server to handle all possible credentials uniformly. |
