A Digital Signature Certificate (DSC) is an electronic form of a signature that ensures the authenticity, integrity, and security of digital transactions. It is issued by a Certifying Authority (CA) and is used to authenticate the identity of the certificate holder in online interactions.

A DSC is required for secure and legally valid online activities, such as e-filing income tax returns, signing legal contracts, participating in e-tendering processes, or verifying identity in online

To obtain a DSC, you need to apply to a licensed Certifying Authority (CA). The process typically involves submitting identity proof, address proof, and completing the required verification steps.

There are three types of DSC:

Class 1: For securing email communications.
Class 2: For verifying the identity of an individual or entity in business and legal filings.
Class 3: For high-security requirements like e-tendering or e-procurement.

Choose based on your intended use; for business transactions, Class 2 or Class 3 is typically required.
