Class 3 Digital Signature Certificate (DSC)
A Class 3 Digital Signature Certificate (DSC) is the highest level of digital signature in India, used for filing documents with the MCA, Income Tax Department, GST portal, DGFT, and various other government portals. It ensures the authenticity, integrity, and non-repudiation of electronically signed documents.
About DSC
