Verify Vehicle Registration Certificate (RC) Digital Signature

When you download your Vehicle RC from the official MoRTH Vahan 4.0 / DigiLocker and view it in Adobe Acrobat Reader or default operating system previewers, you will see a prominent yellow question mark over the signature panel.

This warning occurs because consumer PDF viewers rely exclusively on the Adobe Approved Trust List (AATL), which consists predominantly of commercial Western certificate authorities. In contrast, the Government of India regulates sovereign digital signatures under the Information Technology Act, 2000 via the Controller of Certifying Authorities (CCA) and the Root Certifying Authority of India (RCAI).

Because Western software manufacturers do not bundle India's RCAI root keys by default, unconfigured readers cannot build the certificate validation chain. Kagazo bridges this gap by directly executing the CCA cryptographic validation and embedding a standards-compliant Document Security Store (/DSS) dictionary, rendering the signature permanently valid and green across all devices.

Vehicle Registration Certificates (RC) issued through the Vahan 4.0 national portal certify vehicle ownership, engine/chassis numbers, emission compliance, and hypothecation details with banks.

Digital RC documents downloaded via DigiLocker are digitally signed by MoRTH Vahan using authorized government DSCs.

Kagazo checks the digital signature against the CCA India root chain, verifying vehicle credentials prior to second-hand vehicle purchases or insurance claims.
