Let’s get started.
What is a Digital Signature Certificate (DSC)?
A Digital Signature Certificate (DSC) is a secure digital key issued by a certifying authority (CA) to verify the identity of the person signing a document electronically.
It serves the same purpose as a handwritten signature but in a digital format. A DSC confirms:
The authenticity of the document
The identity of the person signing it
That the document has not been changed after signing
DSCs are legally valid under the Information Technology Act, of 2000 and are widely used in e-filing, e-tendering, e-procurement, and more.
Why Do You Need a DSC?
A Digital Signature Certificate is needed for many online tasks. Here’s why it is useful:
1. Legal and Secure Online Signing
It allows you to sign documents and forms digitally securely and legally.
2. Mandatory for Government Filings
You need a DSC for filing income tax returns, GST, MCA forms, and e-tender applications.
3. Used in Company Registrations
Company directors and professionals must use DSCs when registering or managing companies.
4. Required for e-Tenders and e-Auctions
Many government departments require DSCs for participating in tenders and bidding online.
5. Saves Time
