VeriPatra asks whether a PDF is really signed

Field notes

The checker accepts a PDF or shared link, then compares the document’s signed number with the file as received and checks certificate trust, signer identity, and document coverage. Its displayed score bands run from 0–49 high risk to 80–100 low risk, while an unreachable verification service produces “could not check” instead of an invented score. The page also names Government of India CCA trust roots and distinguishes cryptographic signatures from scanned ink or seals.
