Limitations
- Technical/formal verification only: it does not replace legal or forensic assessments.
- No OCSP/CRL checks are performed, certificate status might have changed.
- Focused on embedded PAdES signatures; it does not cover external signatures or CAdES (.p7m).
- Processing happens locally on your device: the PDF is never uploaded.
