Why Combo DSC for E-Tender
Why E-Tender Portals Require Org Combo DSC (Sign + Encrypt)
E-tender portals require Class 3 Org Combo DSC (Sign + Encrypt) — not just a regular Individual DSC. The Encryption certificate is mandatory because bid documents must be sealed and encrypted before submission to prevent tampering. A bid submitted without encryption is automatically rejected.
🚫 Common mistake: Using an Individual DSC (Sign only) for e-tender bid submission. Individual DSC will be rejected — you must have Org Combo DSC (Sign + Encrypt) for bid submission on all Indian e-procurement portals.
