What Protect PDF with Password does NOT solve (Radical Honesty)
- We cannot recover your file if you forget the password: zero remote storage means no "forgot password" resets.
- Does not prevent authorized readers from capturing desktop screenshots once authenticated.
- Cannot protect against trivial passwords like "123456" susceptible to dictionary attacks.
Privacy Risks & Common Expensive Mistakes to Avoid
Submitting both confidential documents and their secret keys to third-party web portals compromises security. Encrypting locally keeps keys under your exclusive custody.
- Avoids heavy regulatory privacy penalties for transmitting unencrypted personnel payroll data across open networks.
