Digital Signature Certificate (DSC)

A Digital Signature Certificate (DSC) is an electronic equivalent of a handwritten signature, used to authenticate and secure digital transactions in India. It ensures the authenticity, integrity, and non-repudiation of electronic documents through public key cryptography, where a private key signs the document, and a public key verifies it. DSCs are classified into three types—Class 1 for personal use, Class 2 for business and professional activities, and Class 3 for high-security transactions. They are legally recognized under the Information Technology Act, 2000, providing the same validity as physical signatures. DSCs are essential for e-filing income taxes, company registration, government services, and various business activities, streamlining processes, ensuring compliance, and enhancing security. Obtaining a DSC involves selecting a Certifying Authority, submitting identity verification documents, and receiving the certificate after verification. With the growing digitalization in India, DSCs play a vital role in securing online interactions across sectors.
