What is DSC and Who Needs It?
🔐 What is a DSC?
A Digital Signature Certificate (DSC) is an encrypted electronic form of signature issued by a Certifying Authority (CA). It is used to verify identity online, much like a handwritten signature on paper.
🏷️ Types of DSC Based on Usage
| Class | Use Case | Status |
|---|---|---|
| Class 1 | Email verification (rarely used now) | Obsolete |
| Class 2 | Filing tax returns, MCA forms (discontinued) | Replaced |
| ✅ Class 3 | e-Filing, GST, MCA21, e-Tenders, e-Procurement | Mandatory now |
So currently, Class 3 DSC is required for most online government-related tasks.
