DSC stands for Digital Signature Certificate. It is the digital equivalent of a handwritten signature or a stamped seal, but with far additional security and authenticity features. In electronic transactions and communications, a Digital Signature Certificate is used to validate the sender’s identity and ensure the integrity of the delivered data.

A DSC is issued by a certifying authority (CA) after verifying the applicant’s identity against a recognized database. It includes the applicant’s name, email address, public key, validity term, and the digital signature of the certifying authority.

DSCs are widely used for a variety of online transactions and submissions, such as completing GST reports, income tax returns, e-tendering, online bidding, and signing electronic documents. They provide a high level of security and ensure that information supplied electronically is not tampered with or altered during the transmission process.
