Drawn / image signature on a PDF ≠ DSC (USB token / cloud DSC used on MCA, Income Tax, some banks).
Use local eSign (Pdf Buddy) when
- HR offer letters, NDAs, vendor forms between known parties
- The counterparty accepts a visual signature on the PDF
Use a real DSC when
- MCA / ROC filings, Income Tax e-filing that demands DSC
- Contracts that explicitly require Class 2/3 certificates
