Could you build this?
Partial A browser-based signing and verification UI is vibe-codeable with WebCrypto and existing PKI libraries, but correct X.509 chain validation, CMS/CAdES formats, and revocation checking are security-critical and require expertise to get right.
What it would actually take: The stack would be a React SPA using WebCrypto plus a PKI library such as pkijs and asn1js for parsing certificates and CMS/PKCS#7 signatures. The hard parts are correct chain building, validation against trust anchors, CRL/OCSP handling without a backend, and format compliance with standards like CAdES or XAdES. Getting this wrong can produce false verification results, so a security review and knowledge of PKI standards are needed.
