A Digital Signature Certificate (DSC) is an electronic key used to authenticate the identity of the holder and to sign digital documents and transactions. It serves as the digital equivalent of a physical signature or paper certificate, offering enhanced security and ensuring the authenticity and integrity of electronic messages or documents.
Issuing Authority: DSCs are granted by authorized Certifying Authorities (CAs) recognized by the Controller of Certifying Authorities (CCA) under the Information Technology Act, 2000.
Types of Digital Signature Certificates: DSCs are categorized into three types based on the level of authentication:
- Class 1: Provides basic assurance, typically used for individual or personal purposes.
- Class 2: Offers a higher level of security, commonly used for company registration, filing income tax returns, and similar activities.
- Class 3: Provides the highest level of security, typically required for activities like e-tendering, online auctions, and secure transactions.
Application Process: Both individuals and organizations can apply for a DSC through Certifying Authorities. The application process generally includes an identity verification step.
