Cryptographic Trust Proof

Why Do Bank & Government Counters Reject Yellow "?" Marks?

Indian government certificates are signed using CCA India licensed Certifying Authorities (NIC, eMudhra, (n)Code, IDsign). Standard PDF viewers lack India's RCAI Root in their default trust store, showing a yellow question mark. Kagazo resolves the root chain and embeds permanent Long-Term Validation (LTV) directly into the file.

Verification FAQ

Everything You Need to Know

Answers to common questions regarding digital signature validity, security compliance, and password decryption.

Standard PDF viewers like Adobe Acrobat on Windows, Mac, and mobile devices do not include the Controller of Certifying Authorities (CCA India / RCAI) in their default trusted certificate stores. Even though your document was legally signed by a gazetted officer, Tahsildar, or UIDAI HSM, Adobe displays "Validity Unknown" because it cannot resolve the sovereign Indian root. Kagazo verifies the certificate against official CCA India Root CAs and embeds a Document Security Store (DSS) catalog so Adobe Acrobat permanently displays the green checkmark.
