Could you build this?
Partial Image resizing and PDF generation can be vibe-coded, but validating X.509 PKI digital signatures against India's CCA root certificates and modifying PDF signature dictionaries (LTV/DSS) requires specialized cryptography knowledge.
What it would actually take: The solution requires a PDF manipulation backend (or WASM compilation of libraries like Apache PDFBox or Poppler) capable of parsing PKCS#7/CMS cryptographic signatures embedded in PDF signature dictionaries. The system must maintain and parse the complete Indian Root Certifying Authority (RCAI) and CCA trust chain, perform OCSP/CRL revocation checks, and append Document Security Store (DSS) structures to achieve Long-Term Validation (LTV) without invalidating existing byte-range hashes. This requires deep familiarity with the ISO 32000 PDF standard and public key infrastructure.
