2. Why Adobe Reader Shows "Signature Not Verified" (Yellow Question Mark)
RTPS Bihar certificates are issued using NIC Bihar CA signatures. The yellow question mark appearing in PDF viewers is a client-side trust warning. Our platform verifies the cryptographic hash of the PDF to ensure it is authentic and uncompromised.

4. Why Mobile Users Need PDF SignCheck
Most citizens access their certificates on Android and iOS mobile devices. However, mobile web browsers (like Chrome or Safari) and built-in PDF viewers completely ignore embedded digital signatures, showing no signature status at all. PDF SignCheck runs completely in your mobile browser, executing checks in-memory with zero file storage, providing mobile users with instant verified stamps.
5. Legal Validity of Digital Signatures under the IT Act, 2000
According to Section 5 of the Information Technology Act, 2000, electronic signatures validated against a licensed Certifying Authority (like those under the CCA India root) hold the same legal status as traditional handwritten signatures. They are legally binding and accepted by all government offices, courts, and banks. Bihar certificates use NIC Bihar CA cryptographic keys. Our verifier checks the document byte range to ensure no modifications have occurred after signing.
