Class 3 Combo DSC for E-Tendering: Signing + Encryption Token for GeM, Railways & PWD Bids

Class 3 Combo DSC (Signing + Encryption) for E-Tendering & Public Bidding

Government e-procurement portals across India—including the Government e-Marketplace (GeM), Central Public Procurement Portal (CPPP), Indian Railways (IREPS), and Maharashtra PWD (mahatenders.gov.in)—operate on strict cryptographic security protocols to safeguard commercial tender confidentiality. Bidders cannot participate using a standard Signing-only certificate; they require a specialized Class 3 Combo Certificate containing both Signing and Encryption keys.

The Signing certificate authenticates the bidder's identity and verifies tender submission integrity, while the Encryption certificate encrypts financial price bids so that government tender opening committees can only decrypt them during designated commercial bid openings. KOKJAGUAR Consultancy in Pune configures and delivers certified Combo DSC tokens to engineering contractors, suppliers, and service vendors. Explore our GeM and tender registration solutions.
