Digital Signature Certificate (DSC)
A Digital Signature Certificate (DSC) is an electronic form of a physical signature used to authenticate the identity of an individual or organization in digital transactions. Issued by licensed Certifying Authorities (CAs) in India, a DSC ensures the security, integrity, and authenticity of documents submitted online. It plays a crucial role in e-governance and digital communications, helping to establish the identity of the sender and confirm that the information has not been tampered with during transmission. DSCs are widely used for filing various forms and applications with government departments such as the Ministry of Corporate Affairs (MCA), Directorate General of Foreign Trade (DGFT), Income Tax Department, and GSTN.
