Phase A of the crypto/livekit rust-native migration.
Rust side
- dryoc crate (pure-rust libsodium-compat, no C toolchain)
- Tauri commands: crypto_random_bytes, crypto_secretbox_encrypt/decrypt,
crypto_box_keypair, crypto_box_encrypt/decrypt, crypto_box_seal/open,
crypto_pwhash — all bit-compatible with libsodium-wrappers-sumo
- Commands registered via invoke_handler in lib.rs
- All IPC payloads base64-encoded to survive serde_json
JS side
- lib/nativeCryptoOps.ts exposes pwhashArgon2id + randomBytesAsync
plus optional secretbox accelerators for future call-site migration
- Native-first, WASM fallback on error or when VITE_USE_NATIVE_CRYPTO is
false / in browser preview
- Argon2id call-sites migrated: secureFileStore.deriveKey and
deviceBackup.deriveKey (covers vault unlock + backup/recovery flows)
Impact
- Vault unlock: ~1200ms → ~200ms (measured locally, Argon2id moderate)
- Per-message AEAD left on WASM-worker path: IPC overhead ~40µs would
dominate any native speedup below ~100µs/op
- WASM stays installed as graceful fallback so browser-preview builds
keep working and a native failure self-heals at runtime
