Breezip Password - __exclusive__

- The storage file `storage.enc` is encrypted but **not** resistant to offline brute‑force if master password is weak. - Use a **strong master password** (≥12 chars, mixed case, numbers, symbols). - For production, consider adding **key stretching (Argon2)** and **authentication (HMAC)**.
