Digital Signature Certificate (DSC) Services in India – Class 3 DSC, DGFT DSC, Document Signer DSC, Aadhaar e-KYC, IT Act 2000 Compliant Class 3 Token Solutions
A Digital Signature Certificate (DSC) is the cryptographic equivalent of a handwritten signature — issued under the Information Technology Act 2000 by Licensed Certifying Authorities (CAs) accredited by the Controller of Certifying Authorities (CCA), Government of India. Following the harmonisation under CCA's revised guidelines (effective 1 January 2021), India now operates a single class — Class 3 DSC — for all digital signing requirements, replacing the earlier Class 2 / Class 3 distinction. A valid Class 3 DSC, hosted on a secure FIPS 140-2 compliant USB token (ePass / Watchdata / mToken / Hyp2003), provides the authenticity, integrity, and non-repudiation needed for filings on the MCA21 portal, Income Tax e-filing portal, GST portal, EPFO, ESIC, ICEGATE, DGFT, e-Tendering portals (CPP-Portal, GeM, Indian Railways, defence PSUs), TRACES, RBI portals, IRDAI, SEBI, and MahaRERA / state RERA portals.

FAQs on Digital Signature Certificate
What is a Digital Signature Certificate (DSC)?
A DSC is the electronic equivalent of a handwritten signature, issued by Licensed Certifying Authorities under the IT Act 2000. It provides authenticity, integrity, and non-repudiation for documents and filings on government and corporate portals.
What is the difference between Class 2 and Class 3 DSC?
Effective 1 January 2021, Class 2 DSC has been discontinued by the CCA. Class 3 is now the single unified class for all use cases — MCA filings, GST, ITR, e-tendering, and document signing.
How long does it take to get a DSC?
With Aadhaar e-KYC, individual DSC is typically issued in 30–60 minutes. Organisation DSC and Foreign National DSC may take 1–3 working days depending on KYC documentation and verification.
What is the validity of a DSC?
DSCs are issued for 1, 2, or 3 years — the most common is 2 years. Renewal must be completed before expiry; expired DSCs cannot sign and must be re-issued through fresh KYC.
Can DSC be used on Mac and Linux?
Yes. USB tokens like ePass2003, Watchdata, and Hyp2003 have drivers for Windows, macOS, and Linux. Some government portals are best supported on Windows, but most filings work on all three platforms with correct driver and Java configuration.
What is a Document Signer Certificate?
A Document Signer is an organisation-bound DSC hosted on a Hardware Security Module (HSM) for automated, server-side bulk signing — used for e-invoicing, e-way bills, payroll, certificates, and policy documents without needing a USB token.
What if I lose my DSC token or forget the PIN?
A lost token / forgotten PIN cannot be recovered — the DSC must be revoked and a fresh DSC issued. Always store the token securely and remember the PIN; some tokens permanently lock after a few wrong attempts.
