Nick Zana 7f98c2779a fido-common: Fix serde_with version to support serde fork 2 years ago
Nick Zana cfc7856894 Patch serde to github.com/AndrewScull/serde fork
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.

Tracked in <https://github.com/serde-rs/serde/pull/2209>

Nick Zana 6ef8cee4de fido-common: Add attestation::Statement data type
Attestation statements are returned as part of the CBOR maps returned by
authenticators in response to authenticatorMakeCredential and
authenticatorGetAssertion commands.

The attestation statements defined by WebAuthn come in various formats.
However, the format identifier is not part of the attestation statement
field in the CBOR map (0x03 attStmt), but rather as a distinct format
field (fmt 0x01).

Normally, this could be worked around with an externally tagged enum,
but using integer tags is not currently supported by serde. By marking
the enum instead as untagged, this should ideally mean that serde can
differentiate between the enum variants by the fields of the attestation
statement, which is itself a CBOR map.

Otherwise, we could always revert to just raw byte sequences for the
attestation statements during (de)serialization and push validating
these statements onto another part of the code.

Nick Zana a0bd1c9e01 fido-common: De/serialize credential::public_key::UserEntity::id as bytes
Uses serde_with to serialize and deseriailze the UserEntity::id field as
a byte string instead of a sequence (array) of bytes.

Nick Zana 42044f2a46 fido-common: Implement serde for credential::public_key::Descriptor
Adds serde_with as a dependency in order to serialize Descriptor::id as
bytes instead of as a sequence.

Enables cfg_eval feature to enable conditional usage of serde_with
behind the "serde" feature flag for the fido-common crate.

Nick Zana 576addac1f fido-common: Implement Deserialize for authenticator::Data
Requires bitflags to parse CTAP "flags" field of AuthenticatorData.

Implements Deserialize for custom CTAP format for authenticator::Data
byte layout.

Nick Zana 90f75b88d8 fido-common: Implement Deserialize for attestation::CredentialData
Relies on ciborium as a dependency because coset requires one of
ciborium's error types. It should be possible to remove this type's
dependence on ciborium.

Nick Zana 39a5759d12 fido-common: fix credential::public_key::Parameters signature type
The credential::public_key::Parameters field algorithm designates the
public key algorithm represented by the parameter. This replaces the
incorrect registry::algorithms::Signature type with the correct
coset::iana::Algorithm type and adds Serialization/Deserialization
methods for this type.

Nick Zana 8e1b175136 remove bounded_vec from fido_common crate
bounded_vec crate was used to enforce constraints on size of various
fields as defined by webauthn or ctap specs. However, it does not
properly support zero-sized lower bounds.
