CTAP 2 uses bitflags to represent the permissions field in client pin
requests. This adds a RawPermission type that can be represented using a
FlagSet<RawPermission> for Serialization and Deserialization.
The cosey::PublicKey type does not properly implement deserialize for
the general PublicKey type. the client_pin::raw::PublicKey type is used
as an intermediate to allow deserialization of COSE public keys in the
client_pin protocol.
Replaces coset::CoseKey type, which doesn't sufficiently distinguish
between public and private keys and the parameters required for key
algorithm variants, with the cosey::PublicKey type in the Request and
Response type fields.
Rather than use manual lifetime management for PinUvAuthProtocol session
keys, change the auth_protocol::platform::Session trait to represent a
single Session, which maintains its own platform key agreement key, and
can be managed with the lifetime of the value itself.
This unstable feature is used in the
authenticator::client_pin::auth_protocol module to keep track of which
version of the PinUvAuthProtocol a given Authenticator or Platform
interface implements.
In preparation for adding traits for the PIN/UV Auth Protocol, this
splits the AuthProtocolVersion type into its own module and renames it
to auth_protocol::Version.
Used to manage serialization and deserialization of COSE public keys
instead of coset in order to be able to derive De/Serialize for types
that include COSE public keys as fields in CBOR messages.
coset is inadequate for the purpose because it uses a distinct
AsCborSerialize trait instead of the standard serde::{Serialize,
Deserialize} traits.
Derives PartialOrd and Ord for credential::public_key::Parameters
Derives PartialEq, Eq, PartialOrd and Ord for credential::public_key::UserEntity
Also derives clone and copy for some types.
serde_derive does not currently support using integer values as map
keys. CTAP uses integer values for various CBOR map keys. In order to
properly serialize and deserialize types for the CTAP protocol, a forked
version of serde from a pull request that adds support for renaming
field keys as integer types is used.
