A Digital Signature Certificate (DSC) is a requirement for submitting different online forms to the Government of India. It serves as an electronic signature, used for signing electronic documents, emails, and other digital files. DSCs enhance security through encryption technology. They are primarily used by businesses to digitally sign documents online, securely verify the signature, and authenticate the signed copy.
