Could you build this?
Partial While basic PDF manipulation is common, verifying Indian X.509 PKI signatures against the Controller of Certifying Authorities (CCA) trust chain and generating cryptographic PDF stamps requires deep digital signature expertise.
What it would actually take: The stack needs a low-level cryptographic PDF processor (e.g., Apache PDFBox, BouncyCastle, or pyHanko) equipped with complete certificate trust chains from Indian CCAs, CRL (Certificate Revocation List), and OCSP validation. It requires handling ByteRange parsing, timestamp verification (RFC 3161), and non-destructive PDF modification to visually embed verification stamps without invalidating the existing signatures.
