feat: route all applet protocol operations through libcanokey - #27
Conversation
Bump libcanokey to 95e1930e and complete the migration: PIV PQ seed import, OATH set-default, NDEF, Pass and the CTAP transport now use upstream operations via new facade bindings, alongside the previously migrated PIV/OpenPGP/Admin paths. No Dart code builds APDUs by hand anymore (CBOR/ClientPin stays host-side by design). Also converge repeated Admin SELECT/VERIFY onto admin::Access::Existing behind lease-bound session evidence, and cover all native-tagged tests in the USB/IP workflow via --tags native.

the PIV object parsing fix. Remove the incomplete “A separate local The pinned”
text and eliminate the stale alternative claim at the later status entry.

- Around line 311-313: Update _verifyCode to accept a report flag and only
display the pinIncorrect prompt when report is true; call it with report false
for _localCodeCache and LocalStorage candidates, and with report true from the
dialog onSubmit path so failures are reported only for user-submitted codes.
- Around line 154-156: Update setCode to invalidate the existing LocalStorage
entry with LocalStorage.setPinCache(sn, _tag, null) before updating
_localCodeCache and handling the saveCode branch, ensuring the old code is
removed and credential generations are invalidated even when saveCode is false.
- Around line 376-380: Update the oath submit callback around _client.prepare()
and _verifyCode() to catch ProtocolException and StateError in addition to
existing failures. In each handled failure path, perform the required NFC
cleanup and show an error prompt while preserving dialog retry/cancellation
behavior and ensuring the authentication future is not left incomplete.
In `@lib/controller/applets/piv/piv_controller.dart`:
- Around line 1670-1671: Update _putDataObject to catch ProtocolException from
PivCardClient.writeObject and return a failure result so _writePinOnlyObjects
reaches its rollback branches. Ensure rollback re-establishes the required PIV
preparation and authorization before _setManagementKeyInSession, because
_executePrepared discards the prepared profile after a failed exchange.
In `@lib/helper/utils/ctap_transmitter.dart`:
- Around line 36-40: Update _isSelected and the related selection state to track
the CardLease selection generation, not only lease identity, so
willSelectApplet() invalidates the FIDO2-selected marker when another applet is
selected on the same lease. Ensure transceive() calls ctapSelectApplication()
again before ctapTransceiveSelected in that case, and add a regression test
covering FIDO2 selection, another applet selection on the same lease, and
renewed FIDO2 selection.
In `@lib/helper/utils/smartcard.dart`:
- Line 578: Update the C-APDU logging in the command-processing flow to avoid
recording complete credential-bearing APDU strings. Log only non-sensitive

the existing command execution behavior.
- Line 667: Update the removal and failed-probe callers of _disconnectCcidCard
to inspect its boolean result; when it returns false, set _connectionQuarantined
to true, assign connectionError to the cleanup failure message, and prevent
further connection discovery or polling retries until restart, matching

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Invalidate the previously saved code before caching the new one.
setCode changes the device code. When saveCode is false, the old code stays in LocalStorage under the same pin:$sn:OATH key. The next _authenticate reads it, derives a key, and fails validation. The obsolete code also stays on disk.
LocalStorage.setPinCache(sn, tag, null) both removes the entry and bumps the credential generation, so it also clears page-local copies in other CredentialCache('OATH') instances.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not show the incorrect-PIN prompt for silent candidates.
_authenticate calls _verifyCode for the _localCodeCache candidate and for the LocalStorage candidate before it prompts the user. Each failed candidate now shows pinIncorrect. The user sees an incorrect-PIN error without entering anything, and then still gets the code dialog.
Report the failure only for the code the user submitted.

- Future<Uint8List?> _verifyCode(String code, List<int> salt) async {
+ Future<Uint8List?> _verifyCode(String code, List<int> salt,
+ {bool report = false}) async {
final key = OathCardClient.deriveKey(code, salt);

Handle non-PlatformException failures in the oath submit callback.
_authenticate completes its Completer only after successful verification. If _client.prepare() or _verifyCode throws ProtocolException or StateError, the onSubmit callback catches neither error. The async void callback reports an unhandled error and leaves the authentication future incomplete without showing feedback. InputPinDialog resets _submitting in finally, so the dialog remains retryable and cancellable.
Catch these errors in the callback, perform the required NFC cleanup, and show an error prompt.

Return PUT DATA failures and make rollback valid after a rejected write.
PivCardClient.writeObject throws ProtocolException, and SmartCard.process does not convert callback exceptions to a result. Therefore, _putDataObject exits _writePinOnlyObjects before the rollback branches run. The card can retain the new management key without its protected key object, which can lock the user out until a PIV reset.
Catching ProtocolException at _putDataObject is required, but it is not sufficient by itself. After an attempted exchange, PivCardClient._executePrepared discards the prepared profile before rethrowing. The rollback call to _setManagementKeyInSession can then fail with StateError because no profile is prepared. Re-establish the required PIV preparation and authorization before performing the rollback.

CWE: CWE-532 — Insertion of Sensitive Information into Log File
Do not log complete credential-bearing APDUs. Admin, PIV, and OpenPGP operations place PINs or PUKs in APDU command strings that reach this log without redaction. LogStore records these messages by default, retains the latest 500 entries, and exposes them through Settings > View Logs, where users can copy the full text. OATH access codes are derived before transmission, so this finding does not establish that the raw OATH code appears in the APDU.

Quarantine the connection when disconnect cleanup fails.
The removal and failed-probe callers ignore the false result from _disconnectCcidCard(). The removal path clears _ccidCard and continues to connection discovery. The failed-probe path allows later polls to retry. The old handle is not reused directly, but the connection is not quarantined after uncertain cleanup.
When either caller receives false, set _connectionQuarantined = true, set connectionError to the cleanup failure message, and stop reconnection until restart. This matches the cleanup handling in _bindConnection().

Block cancellation while submission is active.
_submitting blocks duplicate submissions, but both cancel controls remain active while widget.onSubmit awaits card I/O. In the WebAuthn _setPin flow, onCancel completes the result with false; the submit callback can then set the PIN and call completer.complete(true). That second completion raises StateError, while the caller has already received a canceled result despite the PIN change.
Guard both cancel callbacks when _submitting is true, or cancel and await the active operation before closing the dialog.

Reused localization key for the unknown slot status.
settingsKeyboardLayoutUnknown belongs to the keyboard-layout setting. This widget displays it as the Pass slot status, so translations written for a keyboard layout can read incorrectly here. Add a dedicated Pass string, for example passSlotUnknown, and use it in this switch arm and in lib/views/applets/pass/dialogs/slot_config_dialog.dart Line 129.

INS 43 sits behind the admin applet's authentication gate on 3.x firmware, so pass slot reads now accept the lease's verified PIN as a fallback when no recorded Admin session evidence is available.
Firmware 3.0.x requires PIV management-key authentication for the INS EE read and resets that status on every SELECT. readAlgorithmExtensions now accepts an optional management key (select, prepare, authenticate and read in one selection), the capabilities refresh keeps its defaults fallback for exactly that 6982 gate, and pass slot reads supply the verified lease PIN on firmware gating INS 43.
WebAuthn now runs on libcanokey's ctap2/ClientPin/credmgmt operations via new facade bindings, replacing the fido2 package, the fido2_crypto crate, its web WASM backend and the CTAP transmitter. Card clients share card_client.dart (ProfileBinding / CardClientBase / ProfileCardClient / AdminSessionCardClient), removing ~470 lines of duplicated boilerplate.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Fix the one-byte length prefix used for RP and user text fields.
ctap_rps_data encodes entry.rp.id and entry.rp.name with a one-byte length prefix, and reserves 0xff to mean "name absent". ctap_credentials_data (lines 2276-2282) uses the same scheme for user.name and user.display_name.
This has two problems:
- A field of exactly 255 bytes produces the length byte
0xff. Dart cannot tell this apart from the "absent" sentinel and reads the field as absent. - A field longer than 255 bytes truncates through
as u8. The length byte no longer matches the real byte count, so Dart reads the wrong number of bytes and misparses every field after it in the same response, including later RP or credential entries.
A WebAuthn relying party sets rp.id, user.name, and user.display_name when it creates a resident credential. Neither the CTAP wire format nor this encoder bounds these fields to 255 bytes. A single long value corrupts the whole enumerate_rps or enumerate_credentials response, not just its own entry.
Widen the length prefix to u16, matching the prefix already used for the credential ID and the COSE key bytes in the same function.
🐛 Proposed fix for ctap_rps_data (apply the same pattern to the two text fields in ctap_credentials_data)
fn ctap_rps_data(entries: Vec<ctap::credmgmt::RpEntry>) -> Vec<u8> {
let mut out = Vec::new();
for entry in entries {
- out.push(entry.rp.id.len() as u8);
+ out.extend_from_slice(&(entry.rp.id.len() as u16).to_be_bytes());
out.extend_from_slice(entry.rp.id.as_bytes());
match &entry.rp.name {
Some(name) => {
- out.push(name.len() as u8);
+ out.extend_from_slice(&(name.len() as u16).to_be_bytes());
out.extend_from_slice(name.as_bytes());
}
- None => out.push(0xff),
+ None => out.extend_from_slice(&0xffffu16.to_be_bytes()),
}
out.extend_from_slice(&entry.rp_id_hash);
}
out
}Update the Dart-side decoder to match the widened prefix, and add a test with a field near or over 255 bytes.

Bump libcanokey to 9110bc71. The PIV algorithm-extension read now goes through the profile-based upstream operation: Access::Management authenticates and reads in one operation on 3.0.x, and the capability gate rejects unsupported or unauthenticated reads before any I/O, so the version-hardcoded fallback and the manual select/prepare/authenticate choreography are gone. CTAP status bytes now arrive via Error::application_status. Pass slot reads rely on the upstream protected-read gate.
The fido2-era exact pins are gone; the wasm-bindgen family now tracks the wasm-bindgen-cli used by the FRB web build, so build-web works with the stock toolchain and no host-side shim. Also bumps semver-compatible dependencies and regenerates THIRD_PARTY_LICENSES.json.
NDEF now honors the CC-advertised file ID and preflights writes against the capability container; PASS requests are gated behind Capability::AdminPassConfig. The migration doc is rewritten as a current-state reference; per-increment history lives in git.

ByteData getUint64/getInt64 are unsupported by dart2js, which broke the WebAuthn page on web; decode both halves with 32-bit accessors instead. PIN-less Admin requests now reuse the probe's selection while it is still current (Access::Existing), dropping a redundant SELECT per read; the Pass slot read stays construction-gated because the card gates it on every audited firmware.
Both are injected at compile time via BUILD_COMMIT/BUILD_TIME dart-defines; CI workflows and the fastlane release lanes inject them automatically, local development builds simply omit the line.
libcanokey's probe now accepts the bootstrap-observed serial; SmartCard records it on the lease at connection setup and every client's prepare passes it through, removing one serial read per refresh.
- Keep PIV profile evidence valid across the 3.0.x gated read (6982) so the page refresh survives the defaults fallback. - Re-confirm the physical card with a real serial read before Admin PIN verification; bootstrap observations no longer stand in for it. - Drop the poll-time session invalidation that could kill in-flight Android NFC operations; rebinding a lease already invalidates. - Zero the OATH access key and WebAuthn PIN copies after use, restore graceful keyboard-keymap degradation, and complete setPinRetries with a failure result instead of propagating metadata-write errors. - Bump libcanokey to f94f40ac (test-only upstream cleanup).
The commit hash links to the GitHub commit page and the build time is shown in local time, both with localized labels.
GITHUB_SHA on pull_request events is a temporary merge commit that exists on no branch, so the About dialog's commit link 404'd. Prefer github.event.pull_request.head.sha (and the event payload in the fastlane lanes).
Bundle IBM Plex Sans, Poppins, Raleway, ABeeZee and Abel as assets and add tool/subset_cjk_font.py to build the CanoKey CJK subset, replacing runtime font downloads and the snap font shims.

Align the libcanokey revision with the release objective.
The objective specifies 95e1930e, but rust/Cargo.toml and rust/Cargo.lock resolve libcanokey to f94f40acaf5bb57906d2edab1fd1b73d0cfdd97e. Update both files if 95e1930e is the intended revision, or update the objective to match the manifest.

In `@rust/Cargo.toml` at line 10, Align the libcanokey revision across the canokey
dependency in Cargo.toml and its resolved Cargo.lock entry with the intended
release objective, using 95e1930e if that is the approved revision; otherwise
update the objective to match the manifest and lockfile.

Make tool/subset_cjk_font.py self-contained: it downloads the pinned Noto Sans SC source (commit-pinned URL, sha256-verified), caches it under build/font-cache, and skips regeneration when the source, script, charset, or weights are unchanged. Output is byte-for-byte reproducible (recalcTimestamp disabled) so CI can verify committed fonts stay in sync with the generator. build.yml and deploy.yml run the script before flutter pub get and fail on drift via git diff --exit-code.
The macOS runner's Homebrew Python rejects plain pip installs (externally-managed-environment); actions/setup-python provides a self-managed interpreter on every platform.
- piv: catch ProtocolException in _putDataObject so pin-only write failures reach rollback; re-prepare and re-authenticate with the new management key before rolling back - protocol: widen CTAP RP/user text field length prefixes to u16 with a 0xffff absent sentinel; reject oversized inputs instead of truncating; update the Dart decoders to match - oath: return safely when authentication is canceled, clear the stale LocalStorage code in setCode, stop reporting pinIncorrect for silent cached candidates, and handle ProtocolException/StateError in the submit callback - smartcard: quarantine the connection when CCID disconnect cleanup fails on the removal and failed-probe paths - input_pin_dialog: ignore cancellation while a submission is active - pass: add a dedicated passSlotUnknown localization instead of reusing the keyboard-layout string

Summary
Complete the libcanokey migration (pin now
95e1930e). Every applet protocol operation — Admin, PIV (incl. PQ seed import, attestation, streaming sign), OATH (incl. set-default), OpenPGP, NDEF, Pass and the CTAP transport — now runs through libcanokey operations via the FRB facade. Dart no longer builds APDUs by hand; CBOR/ClientPin stays host-side by design.Also included:
admin::commandbuilders.admin::Access::Existingbehind lease-bound session evidence (invalidated by cross-applet selection, profile invalidation, uncertain writes, failed Existing requests or lease replacement).--tags native(covers the new OATH/OpenPGP/NDEF/Pass/CTAP transcripts).Local validation
cargo test --locked: 66 passed; strict clippy warning-free; rustfmt clean.flutter test --no-pub: 381 passed (124 native-tagged).cargo check --target wasm32-unknown-unknown, FRB WASM package regeneration andflutter build web --no-pubpassed.Not exercised locally: the USB/IP firmware matrix (covered by this PR's workflow) and physical cards.
