Digital Signature Certificate (DSC)

What is a Digital Signature Certificate (DSC)?

A Digital Signature Certificate (DSC) is an electronic credential issued by a licensed Certifying Authority (CA). It authenticates the identity of the signer and ensures data integrity and non-repudiation when signing electronic documents. DSCs are legally valid in India under the Information Technology Act, 2000.

DSCs are widely used for tax filings, company filings, government tenders, DGFT registrations, trademark submissions, and many other official digital processes. Class 3 DSC is the highest level of DSC used for high-value and sensitive transactions.
