Summary
- Replace hard keytar dependency with a multi-strategy key storage:
1) safeStorage (Electron built-in) — preferred
2) keytar (system keychain) — fallback
3) file-based encryption — last resort
- Dynamically import keytar to avoid asar load failures
- Refactor cloudHandler to use const (clean code)
- Fix “Failed to load cloud accounts” in packaged app
Rationale
The keytar native module can fail to load from asar archives in production builds. This ensures the app works even when system keychain access is unavailable.
Additional changes
- Replace sync file ops with async (fs/promises)
- Add atomic file writes to prevent data races
- Implement concurrency lock for key generation
- Add security error codes for better diagnostics
- Add warnings for file-based fallback mode
- Align error handling after merge
- Migrate legacy encrypted account data
