Digital Signature Certificate (DSC)

A Digital Signature Certificate (DSC) is a secure electronic key used to verify the identity of an individual or entity while signing documents online. It serves as the digital equivalent of a physical signature and ensures authenticity, integrity, and security of electronic filings.

In India, DSCs are issued by licensed Certifying Authorities under the Information Technology Act, 2000.
