What is a Digital Signature Certificate (DSC)?

A Digital Signature Certificate (DSC) is an electronic form of a signature that is used to authenticate the identity of the person signing a digital document. It ensures that the document is secure, authentic, and has not been altered after signing.

In India, DSCs are issued by Certifying Authorities (CAs) licensed by the Controller of Certifying Authorities (CCA) under the Information Technology Act, 2000.

Digital signatures are widely used for online filings, government forms, company registrations, and secure digital transactions.

A DSC helps in:

Ensuring data integrity (document cannot be altered after signing)

Providing security in online transactions

Saving time and paperwork in government filings

Legally validating electronic documents
