A Digital Signature Certificate (DSC) is no longer optional for Indian businesses.
It is required for GST filing, MCA compliance, government tenders, DGFT registrations, and many other official processes.
Yet, one of the most common problems we see at EverSign is this:
“I bought a DSC, but it doesn’t work for my purpose.”
This happens because not all DSCs are the same.
Different portals, departments, and use cases require specific types of DSCs.
Buying the wrong one leads to:
-
Rejected applications
-
Missed deadlines
-
Extra costs
-
Wasted time
This detailed guide will help you choose the correct DSC for your exact need.
What Is a Digital Signature Certificate (DSC)?
A DSC is a secure digital identity used to:
-
Sign documents electronically
-
Authenticate users online
-
Submit government forms
-
Encrypt sensitive data
It is legally recognized under the Information Technology Act, 2000.
A DSC is issued to:
-
Individuals
-
Company directors
-
Authorized signatories
-
Business owners
-
Government officials
Types of DSC in India (Simple Explanation)
Today, most official uses require Class 3 DSC.
Within Class 3, there are two main types:
| Type | Purpose |
|---|---|
| Signing DSC | For signing documents |
| Signing + Encryption DSC | For signing + data security |
Some portals only need Signing, while others need Encryption also.
Why Choosing the Right DSC Matters
If you use the wrong DSC:
❌ Forms may be rejected
❌ Portals may not detect your certificate
❌ Bids may fail

That’s why understanding your use case is critical.

However:

Tender portals often require special encryption DSCs

Token compatibility also matters
So, one DSC does NOT always work everywhere.

Ignoring encryption requirement

Using expired DSC

Mismatch in name/PAN/Aadhaar

These mistakes lead to rejections and delays.

-
