CLASS 3 CONFIGURATIONS

Which Class 3 Certificate Do You Need?

Class 3 Digital Signature Certificates provide the highest grade of cryptographic security. In compliance with the latest CCA guidelines, all new digital signatures issued in India are Class 3. Depending on your regulatory portal, you can choose between two variants:

Class 3 Signing Only (Individual or Organization)

Used for digitally signing PDF documents, MCA V3 filings (Form Spice+, DIR-3 KYC, AOC-4, MGT-7), Income Tax returns, GST invoices & returns, EPFO, Trademark/Copyright filings, and High Court filings.

Class 3 Signing + Encryption Combo (Mandatory for Tenders)

Contains two separate certificates inside one USB token: a Signing Certificate to verify your identity and an Encryption Certificate to encrypt your tender bids, price schedules, and financial bids so only the tender inviting authority can decrypt them after the deadline.

FREQUENTLY ASKED QUESTIONS

Class 3 DSC Questions Answered

Clarify any doubts before submitting your application.

Is Class 3 DSC required for eTendering / GeM portal?

Yes. Government eProcurement and GeM portals strictly mandate a Class 3 Organization Signing + Encryption combo DSC. The signing certificate authenticates bid submission, while the encryption certificate secures the financial bid data.

Can one Class 3 DSC be used for both MCA V3 and Income Tax?

Yes! A Class 3 DSC issued to an individual/director is universally valid across MCA V3, Income Tax, GST, and high court portals.

What validity periods can I choose?

You can choose between 1 Year, 2 Years, or 3 Years validity. 2 Years and 3 Years are recommended as they offer substantial discounts and reduce frequent renewal disruptions.

What if I already have a USB token from an old DSC?

If your old token is a FIPS-compliant model (HYP2003, ePass2003, ProxKey), you do not need to purchase a new token. We can issue the Class 3 DSC directly into your existing token.
