release(v4.5.0): browser-side encrypted storage + multi-factor unlock
Adds the foundations Prism's web client (and any future browser-based
Shade app) needs: at-rest-encrypted IndexedDB storage that mirrors the
SQLite backend byte-for-byte at the AAD/nonce level, browser-safe
subpath imports so Vite/webpack/esbuild stop hitting bun:sqlite, and
KeyManager support for argon2id and N-factor composite unlock.
@shade/storage-encrypted
- EncryptedIndexedDBStorage (subpath: /idb) — full StorageProvider
using one object store per _enc table; reuses aeadSeal/aeadOpen +
row-codec sealers so a row sealed under the SQLite or Postgres
backend decrypts under IDB given the same KeyManager.
bumpPeerIdentityVersion is atomic under one IDB transaction.
- KeyManager argon2id source — memory-hard KDF for low-entropy
secrets (PINs). Backed by @noble/hashes/argon2 (already a transitive
dep). DEFAULT_ARGON2ID exported (m=64 MiB, t=3, p=1).
- KeyManager composite source — HKDF-combine N sub-sources into one
master. Every source mandatory; order significant by design;
composite-of-composite rejected; optional info string for app-level
domain separation.
- Subpath exports (/crypto, /sqlite, /postgres, /idb) plus a `browser`
condition on the default import that resolves to a barrel
excluding the Bun- and Postgres-specific entries. Browser bundles
no longer pull bun:sqlite transitively.
Tests
- 73 tests in shade-storage-encrypted (was 31). New coverage:
argon2id determinism + reject paths, composite same-factors → same
master, wrong-PIN/passphrase/order-swap → different master, info
domain separation, all 28 StorageProvider methods on
EncryptedIndexedDBStorage, fingerprint-mismatch rejection, and
cross-impl roundtrip with EncryptedSQLiteStorage proving the AAD/
nonce derivation is implementation-agnostic.
