1. What is a Tripura e-District Certificate & Why is it Digitally Signed?
Tripura's e-District portal digitally issues resident and income certificates. These PDFs contain secure cryptographic signatures to prevent tampering.
2. Why Adobe Reader Shows "Signature Not Verified" (Yellow Question Mark)
Tripura certificates are signed by NIC Tripura CA. Because Adobe Acrobat doesn't trust this intermediate CA by default, a yellow warning question mark (⚠️) appears. PDF SignCheck checks the signature block against the CCA India root store.

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. Tripura certificates use NIC Tripura CA credentials under the CCA India trust root.
