Why does my government PDF show a yellow question mark?

Indian government PDFs are digitally signed using certificates from NIC, eMudhra, or other CCA India licensed authorities. Adobe Acrobat and most PDF viewers don't include India's Root Certifying Authority (RCAI) in their default trusted certificate store. So even though the signature is completely valid and legally recognised under the Information Technology Act 2000, your PDF viewer shows a yellow question mark because it cannot automatically verify the issuer. Kagazo checks your PDF against the actual CCA India trust hierarchy and gives you a copy with a permanent green tick visible on any device.

Is my document safe? Do you store my PDF?

Your PDF is processed entirely in memory during verification. We never write your file to disk, never store it on our servers, and never share it with any third party. The file is deleted from memory immediately after verification is complete. You can also verify this by checking our open source backend code.

Which documents does Kagazo support?

Kagazo supports any PDF digitally signed under India's CCA certificate hierarchy. This includes e-Aadhaar, PAN card, DigiLocker documents, ITR-V, Form 16, and all state government certificates from Tamil Nadu e-District, AP and Telangana MeeSeva, Karnataka Nadakacheri and eJanma, Kerala Sevana portal, and more.

My Aadhaar PDF is password protected. Will it work?

Yes. Enter your Aadhaar password (first four letters of your name in capital letters followed by your birth year, for example RAMA1995) in the password field that appears after you upload your e-Aadhaar PDF. We decrypt it in memory, verify the signature, and return a verified copy.

What is the difference between "Signature Valid" and "Signature Unknown"?

Signature Valid means the document is genuinely issued by the government authority and has not been modified. Signature Unknown means your PDF viewer cannot verify the certificate chain — this is a viewer configuration issue, not a problem with your document. Signature Invalid means the document may have been tampered with or re-saved after signing.

Does this work on mobile?

Yes. Kagazo is fully mobile responsive and works on any Android or iOS browser. No app installation required. Simply open kagazo.in on your phone browser, upload your PDF and verify instantly.

Frequently Asked Questions

Q:Why does self-attestation require both signature and date?

Government recruitment boards (UPSC, SSC, State PSCs) require self-attestation to establish that the candidate certifies the document as an authentic true copy on a specific date before submission.

Q:Will stamping blur my certificate or marksheet text?

No! Unlike generic image editors that re-rasterize PDFs into low-resolution JPEGs, Kagazo overlays the stamp layer directly onto the existing PDF vector structure. Your grades, roll numbers, and board watermarks stay razor sharp.

Q:Can I choose between blue ballpoint and black ink?

Yes. You can switch between Royal Blue (#0C2D8C) and Black (#121212) ink depending on your board requirement. Both options feature transparent backgrounds that blend naturally onto white certificates.

Q:Is my uploaded certificate or marksheet saved on Kagazo servers?

Never. All documents and signatures are processed exclusively in volatile RAM memory with zero server disk persistence. Everything is purged immediately once your stamped PDF is generated.
