What is SigVerify?
SigVerify is a free tool for checking digital signatures in PDFs, especially Indian eSign and DSC files. You upload a signed PDF and it gives a detailed cryptographic report with signer identity, certificate chain, timestamp, tamper detection, and trust level. It supports Aadhaar eSign, DSC, PAdES, and PKCS#7, and does the verification on the server side before deleting the file. The product is built for citizens, developers, and legal professionals who need to understand whether a signature is real, valid, and legally trustworthy. It also includes educational content about digital signatures in India, trusted certifying authorities, and the IT Act.
