Digital Signature Certificate (DSC)

What is Digital Signature Certificate?

The full form of DSC is Digital Signature Certificate. A Digital Signature Certificate is an electronic form of a physical certificate used to verify the identity of an individual or organization while conducting online transactions. It is used as identity proof for accessing online services or digitally signing documents.

In other words, a Digital Signature Certificate is the digital version of an individual's physical signature. It is used to authenticate electronic documents and verify the identity of the signer. DSCs are commonly used for filing Income Tax Returns (ITR), signing MCA documents, GST filings, and other government-related online services.

Digital signatures are legally recognized in India under the Information Technology Act, 2000.

Types of Digital Signature Certificate

There are three categories of DSC, which are given below:

Class 1

This certificate is issued to private subscribers and individuals. It provides basic security and verifies the name and email ID of the user.
