Digital Signature Certificate (DSC) in India
What is a Digital Signature Certificate (DSC)?
A Digital Signature Certificate (DSC) is an electronic equivalent of a handwritten signature or a stamped seal, providing authentication of the identity of the holder and ensuring the integrity and non-repudiation of electronic documents. A DSC uses asymmetric cryptography, involving a public-private key pair, to digitally sign documents, emails, and other electronic records.
DSCs are issued by Certifying Authorities (CAs) licensed by the Controller of Certifying Authorities (CCA) under the Information Technology Act, 2000, and are legally recognized under Indian law for e-filing with government portals such as:
- MCA (Ministry of Corporate Affairs) for company and LLP filings
- Income Tax Department for tax returns and e-assessments
- GST Portal for GST filings and refund claims
- Customs and DGFT for imports, exports, and trade-related filings
- Government e-Tendering platforms
Class 3 DSC is now mandatory for all professional, business, and government regulatory filings, ensuring the highest level of security.
