Digital Signature Certificate : What is it & Why is it important?

DSCs are the digital equivalent (electronic format) of physical or paper certificates. Driver’s licences, passports, and membership cards are some examples of tangible certificates.

Certificates serve as verification of an individual’s identification for a certain purpose; for example, a driver’s licence identifies someone who may legally drive in a specific nation. A digital certificate, similarly, may be submitted electronically to establish one’s identity, get access to information or services on the Internet, or digitally sign particular papers.

The digital signature is issued by a certified Certifying Authority (CA). Section 24 of the Indian IT-Act 2000 defines a Certifying Authority (CA) as a person who has been given a licence to issue a digital signature certificate.


A digital signature is a mathematical approach for validating the validity and integrity of a communication, piece of software, or digital document. It’s the digital counterpart of a handwritten signature or a stamped seal, but it’s significantly more secure. A digital signature is designed to prevent tampering and impersonation in digital communications. Digital signatures can be used to verify the origin, identity, and status of electronic documents, transactions, or digital messages. They can also be used by signers to acknowledge informed consent.
