Why This Matters
Government e-procurement portals mandate Class 3 Signing and Encryption DSCs. Verifying details and renewing certificate validity before bidding prevents portal lockouts.
Filing government bids and participating in online auctions in India requires a Digital Signature Certificate. Specifically, e-procurement portals mandate a Class 3 DSC with both Signing and Encryption certificates. Let's look at how to obtain and use it correctly.
1. Why Signing & Encryption (Combo) is Required
A Class 3 Combo DSC contains two distinct digital certificates stored on a single secure USB token:
- Signing Certificate: Authenticates the bid document, ensuring it was signed by the authorized representative.
- Encryption Certificate: Encrypts the bid contents (especially financial pricing sheets) so that portal admins cannot view rates until the public bid opening date.
2. Steps to File Bids with DSC
Ensure you install the correct USB token drivers and browser plugins (like Java or PKI components) specified by the portal. Map your DSC to your user profile on the tender portal before the bid closing deadline.
