What is a Digital Signature Certificate (DSC)?
Introduction:
In today’s digital procurement landscape, every contractor, supplier and MSME participating in government tenders must possess a valid Digital Signature Certificate. Whether you are bidding through the Maharashtra eProcurement Portal or Mahatenders portal, GeM or Central Public Procurement Portal , DSC is mandatory for authentication, bid signing and submission.This guide explains everything contractors need to know - from what a DSC is, how to obtain one, its legal standing under Indian law and how IndianTenders.in helps streamline the process.
What is a Digital Signature Certificate?
A Digital Signature Certificate Or DSC is the electronic equivalent of a physical signature used to validate identity and ensure the authenticity of electronic documents. Just as a passport or driving license confirms your identity in the physical world, a DSC serves as your secure digital identity in the online procurement ecosystem.It is stored in a secure USB token and used to sign tender documents, forms and contracts electronically - making your eTender submission legally valid and tamper-proof.
Why Contractors and MSMEs Need a DSC for eTendering
In India, all major government departments, PSUs and state procurement systems mandate DSCs for online tender participation.
A DSC helps:- Verify the identity of the bidder
- Ensure bid integrity and authenticity
- Prevent unauthorized access or data manipulation
- Legally validate documents submitted online
Legal Framework : IT Act, 2000 and Section 24
Digital Signatures are legally recognised under the Information Technology Act, 2000.
As per Section 24 only licensed Certifying Authorities (CAs) authorised by the Controller of Certifying Authorities i.e CCA, Government of India, can issue DSCs. Once issued, a DSC carries full legal validity and can be produced in a court of law as admissible evidence, just like a handwritten signature.Types of Digital Signature Certificates
There are three primary classes of DSCs in India:- Class 1 DSC: Basic identification, generally not used for eTendering.
- Class 2 DSC: Used for business registration or form filing. (Phased out in many cases)
- Class 3 DSC : Mandatory for e-endering and e-Procurement. It provides the highest level of assurance and requires physical verification by a Registration Authority (RA).
How to Obtain a DSC : Step by Step Guide
- Select a Licensed Certifying Authority (CA): Choose from approved CAs listed on the CCA website.
