Cheapest Class 3 DSC – Complete Guide Based on Real Experience

Introduction

When I first started helping clients with GST filing, DGFT applications, and e‑tender submissions, one question came up again and again:

“Which is the cheapest Class 3 DSC that will actually work on government portals?”

Most users are not looking for the lowest price only—they want a reliable Class 3 Digital Signature Certificate that doesn’t fail during urgent filings. Over the years, after issuing and supporting thousands of DSCs, I’ve learned that choosing the right cheapest Class 3 DSC is about price + compatibility + support.

A Class 3 DSC is not optional anymore. It is mandatory for many Indian government portals, and without it, your compliance work can completely stop.

2. What Is the Cheapest Class 3 DSC?

Meaning (Simple Explanation)

A Class 3 Digital Signature Certificate (DSC) is the highest-level digital identity used in India for secure online authentication, signing, and encryption.

When people search for “cheapest Class 3 DSC”, they usually mean:

• Lowest market price
• Government‑portal compatible
• Comes with a USB token
• Quick issuance & renewal

Technical Overview

A Class 3 DSC includes:

• Private key (stored securely in a USB token)
• Public key (used by portals to verify your identity)
• CA-issued certificate (from licensed authorities like eMudhra, XtraTrust, Vsign, Prodigisign)

Relation with the DSC Ecosystem

Class 3 DSCs are used across:

• MCA
• GST
• DGFT

Without a Class 3 DSC, these systems will not allow digital signing.
