Frequently Asked Questions
Do e-tender portals require a Class 3 DSC?
Yes - government e-procurement portals (CPPP, GeM, state portals) require bidders to register and sign with a Class 3 DSC, often with both signing and encryption certificates. The portal handles bid-submission signing; this tool signs the PDF documents you attach.
Which tender documents should be DSC-signed as PDFs?
Declarations, undertakings, authorisation letters, technical bid annexures, and price justification documents commonly need the bidder's signature. A DSC signature on the PDF is verifiable and tamper-evident, unlike a pasted signature image.
Is bid confidentiality maintained during signing?
Yes. The document is signed inside your browser - only a cryptographic hash is sent to your USB token via a localhost bridge. Your pricing and technical documents never leave your machine before you submit them on the portal yourself.
What if the tender asks for signatures on every page?
A digital signature covers the entire document cryptographically, which many portals accept in place of page-wise signatures. If the tender explicitly demands page-wise marks, check with the tendering authority whether a single DSC signature satisfies the requirement - it usually does for e-submissions.
