In this complete guide, we will explain what a DSC is, its types, uses, benefits, pricing, renewal process, and how businesses can apply for a Class 3 DSC online in India.
What is a Digital Signature Certificate (DSC)?
A Digital Signature Certificate is an encrypted electronic signature issued by authorized Certifying Authorities (CA) in India. It works as a secure digital identity for individuals and organizations while performing online transactions and document verification.
A DSC helps authenticate the identity of the signer and ensures that the documents submitted online are genuine, secure, and tamper-proof.
Digital Signature Certificates are legally valid under the Information Technology Act, 2000, making them mandatory for many government and business-related online processes.
