refactor(auth)!: share canonical signing public keys - #7733
Mesh enrollment and signed content each defined the same Ed25519 identity and canonical text codec. The draft vector generator also duplicated the JS codec.
Approach
Use moq_crypto::sign::PublicKey directly throughout mesh auth. Move byte access (from_bytes, as_bytes) and canonical string serde onto it, and remove auth's codec and data-encoding dependency.
✅ Dependency boundary (maintainer, 2026-11-03): publish moq-crypto with a key-only dependency path. Not chosen: a separate publishable leaf crate.
moq-crypto drops publish = false.
The sign and e2ee modules sit behind default features of the same names. With default features off, the crate is only sign::PublicKey, sign::InvalidKey, and the z-base-32 codec; serde adds the key's string serialization. SecretKey moves to sign/secret.rs so the key file needs no signing backend.
moq-auth depends on moq-crypto with default-features = false, features = ["serde"].
just rs crypto-key (run by just rs features, i.e. features.yml) fails if that tree gains moq-net or aws-lc-rs, and lints and tests the key-only build. The key vectors and refusals now run in the key-only build too.
✅ EndpointId conveniences (maintainer, 2026-11-03): option 1, no new helpers, as implemented. Build mesh paths with Pattern::subtree(&format!("mesh/{endpoint}")); verify with Proof::verify, or an Ed25519 verifier over PublicKey::as_bytes() for another message. Not chosen: a public mesh path helper and public raw PublicKey verification.
Keep enrollment proof verification on rind. Keep mesh publish-path construction in auth.
Both decisions settled, so this PR finishes the quest and deletes it and its link in quest/m1/README.md.
Reuse js/crypto/src/sign/zbase32.ts from the draft generator. Auth has no JS endpoint codec to migrate.
Run auth JSON, Rust crypto, and JS crypto against drafts/moq-sign-00.json, including zero/ones keys and noncanonical text refusals.
Merged origin/main (after moq-dev/moq#7702's rename) and moved everything onto moq-crypto/js/crypto paths; the release-gate TS filter now lists rs/moq-crypto/**.
Impact
Breaking auth API: replace mesh::EndpointId with moq_crypto::sign::PublicKey and mesh::InvalidEndpoint with moq_crypto::sign::InvalidKey; endpoint.publish() and raw endpoint.verify() have no replacement helper. See rs/moq-auth/MIGRATE.md under Unreleased.
Auth's new dependency is key-only: cargo tree -p moq-crypto --no-default-features --features serde -e normal is data-encoding, serde, and thiserror only, and moq-auth with --all-features has no moq-net or aws-lc-rs.
moq-crypto: sign and e2ee are default features, so default users see no change; default-features = false users must add them. PublicKey gains public from_bytes/as_bytes and optional serde. Recorded in rs/moq-crypto/MIGRATE.md.
JS public API and wire: unchanged. Enrollment JSON, persisted IDs, tokens, key text, and signed-frame bytes keep their formats.
Release notes
No .release-plz.toml or release.toml change is needed: release-plz publishes every workspace crate without publish = false, so moq-crypto joins the next release at whatever version release-plz picks (manifest is 0.0.11; no bump made here).
moq-crypto has never been on crates.io, so its first publish needs CARGO_REGISTRY_TOKEN, and it then needs a trusted publisher. Added to the not-yet-published list in quest/m1/crates-trusted-publisher.md.
cargo package -p moq-crypto alone fails today for the same reason it fails for moq-net: workspace kio/moq-pattern carry unreleased features at already-published versions, which release-plz bumps first. With those bumped in a scratch tree (restored), cargo package -p kio -p kio-macros -p moq-pattern -p moq-net -p moq-crypto packaged and verified moq-crypto.
Checks
On the merge with origin/main:
just rs crypto-key: tree assertion passed; key-only clippy (with and without serde) clean; 2 key-only tests passed.
cargo clippy -D warnings for moq-crypto and moq-auth with --all-features, and moq-crypto with only sign and only e2ee; cargo doc -D warnings; cargo fmt --check; cargo shear; cargo sort --check; nextest for moq-crypto + moq-auth --all-features: 334 passed, 1 skipped.
cargo hakari generate --diff and sh/rs/hakari.py: clean (workspace-hack now matches main). cargo metadata --locked: clean.
Not run: full just ci and the whole just rs features matrix.
After the later conflict-free merge of origin/main and the quest deletion: cargo metadata --locked, cargo hakari generate --diff, sh/rs/hakari.py, and quest check --base origin/main (561 documents) passed.
Review
mechanical fix by quest land watch: merged main at c95bf6074251d63a82ce350b1251bd31a09220cb with the quest merge driver (head a97e28d)
quest review --new --base origin/main: Codex, gpt-6.1-sol, medium effort, round 1 reviewed 7b043ced8dd5dde6f02559d7b55abbf112bb8753: no findings.
Final head 8b7ef5ddb48c1c2d02b15b30ab069c697e59e34d: review skipped. Since the reviewed head it adds only a conflict-free merge of origin/main and the quest deletion recording the maintainer's EndpointId decision (docs only); git diff origin/main...HEAD outside quest/ is identical to that of 7b043ced.
The earlier round on 6e0b9a8b27's two findings (published auth requiring unpublishable signing; auth acquiring transport and aws-lc-rs for a key) are fixed by the boundary decision above. No review threads or automated findings were open.
Follow-ups
None new. The moq-crypto first publish and trusted publisher are tracked in quest/m1/crates-trusted-publisher.md.
Resolve against the moq-crypto rename (#7702) and implement the
maintainer's 2026-11-03 decision: publish moq-crypto with a key-only
dependency path.
- moq-crypto drops `publish = false`. Default `sign` and `e2ee` features
gate those modules; without them the crate is only `sign::PublicKey`,
`InvalidKey`, and the z-base-32 codec, with optional `serde`.
- SecretKey moves to sign/secret.rs; the key codec tests run key-only.
- moq-auth depends on moq-crypto with default features off, so it gains
neither moq-net nor aws-lc-rs.
- `just rs crypto-key` (run by `just rs features`) asserts that tree and
lints and tests the key-only build.

Design change: the maintainer decided on 2026-11-03 to publish moq-crypto with a key-only dependency path (Option 2 of the dependency-boundary decision), not a separate leaf crate.
Since moq-dev/moq#7702 merged moq-sign into moq-crypto, this PR now:
drops publish = false from moq-crypto;
gates the sign and e2ee modules behind default features of the same names, so default-features = false leaves only sign::PublicKey, sign::InvalidKey, and the z-base-32 codec, plus an optional serde feature;
has moq-auth depend on moq-crypto with default features off and serde, so auth pulls in neither moq-net nor aws-lc-rs.
The EndpointId conveniences decision (publish() and raw verify) is still open under ## Decisions needed.
Maintainer decision 2026-11-03: ✅ option 1, no EndpointId convenience
helpers, as already implemented. Use `Pattern::subtree(&format!("mesh/{endpoint}"))`
for mesh paths and `Proof::verify` or a verifier over `PublicKey::as_bytes()`
for signatures. With the dependency boundary also settled, this PR
completes the quest, so delete it and its link.

The pull request makes moq-crypto publishable and adds feature-gated signing and encryption functionality. Its PublicKey type and z-base-32 codec can be used without the sign feature. Mesh auth replaces its local endpoint identifier with PublicKey, and the TypeScript draft uses the shared codec. The changes also add secret-key persistence and update related tests, documentation, and build checks.
Merge Risk: Low · up to a97e2
The refactor has a bounded migration-documentation issue: copying the publish-pattern replacement causes a compile error until its Result is handled. Correct the example; device restart coverage is useful follow-up. The retained key-file concerns are unchanged existing behavior.

Reviewed changes
One endpoint key type: moq_auth::mesh::EndpointId/InvalidEndpoint are replaced by moq_crypto::sign::PublicKey/InvalidKey across Proof, Member, Device, Signer::endpoint, and Coordinator::revoke_device; mesh paths now use Pattern::subtree(&format!("mesh/{endpoint}")).
Feature-gated moq-crypto: publish = false is gone, sign and e2ee are default features, PublicKey gains from_bytes/as_bytes plus opt-in serde, and SecretKey moves to sign/secret.rs. The workspace dependency defaults features off, so moq-auth takes only serde.
Key-only CI check: just rs crypto-key asserts the --no-default-features tree lacks moq-net/aws-lc-rs and lints/tests that build.
Canonical vectors: the draft generator reuses js/crypto's z-base-32 codec; new zero/ones keys and padding, whitespace, newline, and base64url refusals run in Rust and JS.
Quests/release: the mesh key quest is deleted, crates-trusted-publisher.md records the first publish, and the release-gate TS filter includes rs/moq-crypto/**.
ℹ️ Key-only docs fail with broken intra-doc links
The newly supported key-only build compiles and tests cleanly, but its rustdoc does not. RUSTDOCFLAGS="-D warnings" cargo doc -p moq-crypto --no-default-features --features serde errors on four links to gated items, and the new crypto-key recipe does not run rustdoc, so CI will not catch this.
Technical details
# Key-only rustdoc errors## Affected sites-`rs/moq-crypto/src/lib.rs:4` — the `[e2ee]` link when the `e2ee` module is gated out.
-`rs/moq-crypto/src/sign/mod.rs:4` — the `[SecretKey]` link when the `sign` feature is off.
-`rs/moq-crypto/src/sign/mod.rs:13,15` — the `[broadcast::Producer]` and `[broadcast::Consumer]` links are gated with `sign`.
## Required outcome-`RUSTDOCFLAGS="-D warnings" cargo doc -p moq-crypto --no-default-features --features serde` succeeds.
-`just rs crypto-key` checks it, the way `just rs coroutines` checks kio/moq-net's no-default-features docs.
## Suggested approach (optional)- Give the gated paragraphs `#[cfg_attr(not(feature = "sign"), doc = "...")]` variants (and likewise for `e2ee`), or change the gated items to plain code spans.
ℹ️ Two "workspace-only" claims outlived the publish change
Removing publish = false makes two tracked statements false. doc/lib/rs/index.md:38 still calls moq-crypto "Workspace-only", and quest/m2/e2ee/cli.md:11 still says "the crate currently sets publish = false while it is workspace-only". The repo rule that a fact this change makes stale is fixed inline applies to both; the GitHub source link in index.md can stay until the first release, per that page's intro.
Technical details
# Stale workspace-only claims## Affected sites-`doc/lib/rs/index.md:38` — table row begins "Workspace-only end-to-end encryption...".
-`quest/m2/e2ee/cli.md:11-12` — "Make `moq-crypto` publishable with this CLI consumer; the crate currently sets `publish = false` while it is workspace-only."
## Required outcome- Neither file states that `moq-crypto` is unpublished; the quest keeps its remaining CLI-consumer scope without the obsolete publish premise.

Reviewed changes
Base merge only: the sole new commit a97e28d is a clean two-parent merge of origin/mainc95bf60. No PR-owned file changed relative to 8b7ef5d: rs/moq-crypto, rs/moq-auth, drafts, sh/drafts, Cargo files, js/crypto, and the release-gate workflow are byte-identical, and the PR's mesh-key-codec deletion is preserved.
Base noise: quest/m1/README.md now reflects main's deletion of the demand-cancel-race line, which is unrelated to this PR.
ℹ️ Prior docs-only findings are still unaddressed
Because the branch merge changed no code, the two ℹ️ findings from the 8b7ef5d review remain exactly as reported: the key-only moq-crypto build does not pass rustdoc with -D warnings, and two tracked "workspace-only" statements are now false. They are not new to this delta, but they still block approval until fixed or explicitly deferred.

load_or_generate syncs the key file but not the directory that holds it. After a power loss, the file can be missing on restart, and a new endpoint key is generated. On Unix, open the parent directory and call sync_all() after the key file's sync_all().

Cover device persistence in the restart test.
state_survives_a_restart saves only a revoked key and reads back only keys(). It does not create a device, so the reload of Device records through Store is not tested. The shared PublicKey text codec is covered through Member in endpoint_vectors, but a change limited to Device loading would pass the current tests.
Enroll one device in the restart test, then assert that restarted.devices() returns its endpoint. The unit tests already enroll devices through coordinator.enroll(&enroll(...)), so the same helper applies.

Fix the Pattern::subtree example in the migration guide.
Pattern::subtree returns a Result, but the guide shows it as a direct replacement for endpoint.publish(), which returned a Pattern. A user who pastes the expression into Claims::with_publish gets a type mismatch and a compile error. Add ? or .expect(...) to the example.

Document the Windows key file permission limit, or enforce it.
load_or_generate documents a 0600 key file and rejects an existing file that other users can read. On non-Unix targets, the file is created with the default ACL, and load skips the exposure check. A key stored in a directory whose ACL allows other users to read it is loaded silently and can be used to sign as the endpoint. Either state this limit in the docs or enforce the ACL on Windows.

Update load_or_generate and load to address the Windows key-file permission gap:
either document that Windows ACLs are not enforced and that the key may be
exposed through its file or directory permissions, or enforce an appropriate
Windows ACL check and reject exposed keys. Preserve the existing Unix permission
behavior.

Write the key file atomically so a concurrent start cannot read it half-written.
load_or_generate creates the key file with create_new before it writes the seed. A second process that starts in that window reads an empty file. decode rejects it, so the second process returns InvalidData and fails to start. Write the seed to a temporary file in the same directory, sync it, then std::fs::hard_link it to path. On AlreadyExists, load the existing key and remove the temporary file. Keep mode 0600 on the temporary file.
Filesystems without hard-link support need a separate fallback. This fix needs a concurrent-creation test, which the current tests do not cover.

Update load_or_generate to avoid exposing a partially written key: write to a
same-directory temporary file with mode 0600, sync it, then atomically publish
it without overwriting an existing key. On a concurrent creation, load the
existing key and remove the temporary file; establish a safe atomic fallback for
filesystems that do not support hard links. Add a concurrent-creation test that
verifies both starts succeed and use the same key.

Problem
Mesh enrollment and signed content each defined the same Ed25519 identity and canonical text codec. The draft vector generator also duplicated the JS codec.
Approach
moq_crypto::sign::PublicKeydirectly throughout mesh auth. Move byte access (from_bytes,as_bytes) and canonical string serde onto it, and remove auth's codec anddata-encodingdependency.moq-cryptodropspublish = false.signande2eemodules sit behind default features of the same names. With default features off, the crate is onlysign::PublicKey,sign::InvalidKey, and the z-base-32 codec;serdeadds the key's string serialization.SecretKeymoves tosign/secret.rsso the key file needs no signing backend.moq-authdepends onmoq-cryptowithdefault-features = false, features = ["serde"].just rs crypto-key(run byjust rs features, i.e. features.yml) fails if that tree gainsmoq-netoraws-lc-rs, and lints and tests the key-only build. The key vectors and refusals now run in the key-only build too.Pattern::subtree(&format!("mesh/{endpoint}")); verify withProof::verify, or an Ed25519 verifier overPublicKey::as_bytes()for another message. Not chosen: a public mesh path helper and public rawPublicKeyverification.quest/m1/README.md.js/crypto/src/sign/zbase32.tsfrom the draft generator. Auth has no JS endpoint codec to migrate.drafts/moq-sign-00.json, including zero/ones keys and noncanonical text refusals.origin/main(after moq-dev/moq#7702's rename) and moved everything ontomoq-crypto/js/cryptopaths; the release-gate TS filter now listsrs/moq-crypto/**.Impact
mesh::EndpointIdwithmoq_crypto::sign::PublicKeyandmesh::InvalidEndpointwithmoq_crypto::sign::InvalidKey;endpoint.publish()and rawendpoint.verify()have no replacement helper. Seers/moq-auth/MIGRATE.mdunder Unreleased.cargo tree -p moq-crypto --no-default-features --features serde -e normalisdata-encoding,serde, andthiserroronly, and moq-auth with--all-featureshas nomoq-netoraws-lc-rs.signande2eeare default features, so default users see no change;default-features = falseusers must add them.PublicKeygains publicfrom_bytes/as_bytesand optional serde. Recorded inrs/moq-crypto/MIGRATE.md.Release notes
.release-plz.tomlorrelease.tomlchange is needed: release-plz publishes every workspace crate withoutpublish = false, somoq-cryptojoins the next release at whatever version release-plz picks (manifest is0.0.11; no bump made here).moq-cryptohas never been on crates.io, so its first publish needsCARGO_REGISTRY_TOKEN, and it then needs a trusted publisher. Added to the not-yet-published list inquest/m1/crates-trusted-publisher.md.cargo package -p moq-cryptoalone fails today for the same reason it fails formoq-net: workspacekio/moq-patterncarry unreleased features at already-published versions, which release-plz bumps first. With those bumped in a scratch tree (restored),cargo package -p kio -p kio-macros -p moq-pattern -p moq-net -p moq-cryptopackaged and verified moq-crypto.Checks
