kv-store: SQLite (bundled) and in-memory Store holding only ciphertext envelopes, with base copies for three-way merges and a 10-version history. kv-ffi: VaultCore::open(path); persisted account record; local unlock key (enable/unlock_with_local_key/disable); async sync API (configure_server, set_device_signer, register_account, login, sync_now, logout, devices); DeviceSigner foreign trait; IntegrityAlarm/PinMismatch/... error variants. kv-sync: reqwest + rustls (TLS 1.3 only, ring) with SPKI pinning; OPAQUE client on kv-proto's OpaqueSuite; RFC 9421 signing per kv_proto::httpsig; pull/push with If-Match, field-level three-way merge, edit-beats-delete; signed manifest (canonical CBOR, Merkle root, prev chain, Ed25519) with rollback/fork/Merkle checks as hard integrity alarms. Tested against a wiremock fake server, plus an #[ignore] test against kestrove-server. kv-crypto: gen-vectors example and tests reproducing kestrove-spec/vectors.

kestrove-core
Rust workspace that holds all Kestrove crypto and vault logic. Apple,
Android and desktop apps call it through UniFFI. The server uses only kv-proto.
| Crate | Status | Purpose |
|---|---|---|
kv-proto |
✅ M0 | Wire types (Envelope, KDF params, API bodies). No secrets. |
kv-crypto |
✅ M0 | 2SKD (Argon2id + Secret Key), XChaCha20-Poly1305 envelopes, HPKE vault-key sealing, keyset, Ed25519, Secret Key format |
kv-model |
✅ M0 | Items, URL matching (PSL), TOTP (RFC 6238), password generator |
kv-ffi |
✅ M1 | The exported API (VaultCore with SQLite storage, local unlock key, sync; totp_code, match_url, generate_password) |
kv-store |
✅ M1 | SQLite replica (ciphertext only), base copies for merges, 10-version history |
kv-sync |
✅ M1 | TLS 1.3 + SPKI pins, OPAQUE login, RFC 9421 signing, pull/push/merge, signed manifest |
Spec: ../kestrove-spec/docs/02-cryptography.md and 03-sync-protocol.md.
Setup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # once
cargo test --workspace
Bindings
./scripts/build-apple.sh # → ../kestrove-apple/Packages/KestroveCore (XCFramework + Swift)
./scripts/build-android.sh # → ../kestrove-android/core-ffi (jniLibs + Kotlin); needs cargo-ndk
The desktop (Tauri) app depends on kv-ffi directly as a Rust crate.
Test vectors and the live-server test
cargo run -p kv-crypto --example gen-vectors # writes crates/kv-crypto/tests/vectors and ../kestrove-spec/vectors
cargo test -p kv-ffi --test live_server -- --ignored # against a fresh local kestrove-server; see the test's docs
Rules
- No
unsafeoutside generated FFI glue. - Secrets live in
Zeroizing<_>. Never log,Debug-print orformat!a secret. - Any change to formats needs a spec change first and new vectors in
kestrove-spec/vectors. cargo deny checkmust pass. There are no GPL dependencies (App Store).
