A Digital Signature Certificate (DSC) is a secure electronic credential issued by a licensed Certifying Authority (CA). It is used to digitally sign documents and authenticate the identity of the signer for online transactions and government portal filings, ensuring security, authenticity, and legal validity.

The required documents generally include the applicant's PAN Card, Aadhaar Card, passport-size photograph (where applicable), mobile number, email ID, address proof, and completion of the prescribed identity verification process (eKYC or video verification), depending on the Certifying Authority.
