What is a Digital Signature Certificate (DSC)?
A Digital Signature Certificate (DSC) is an electronic form of identity proof, similar to physical documents like PAN or passport, but used digitally to authenticate a person or organization. It enables secure access to online services and allows users to digitally sign documents, saving time and simplifying e‑governance interactions. All DSCs in India follow the IT Act, 2000, and the X.509 PKI standards.

Individual Class 3 – Combo/Sign Only and Organisation Class 3 – Combo/Sign Only (depends on portal & tender category).
