Quick Answer

Why is key recovery available for Encryption DSC but never for Signing DSC in Guindy Industrial Estate, Chennai?

Encryption DSCs may be issued with a key escrow facility — the CA archives an encrypted copy of the private key so that an organisation can recover documents if an employee leaves or loses the token. Signing DSCs, by contrast, carry the nonRepudiation bit. Section 3 of the IT Act 2000 and Indian Evidence Act Section 65B require that only the signatory could have created the signature. Any escrow of the signing private key destroys the non-repudiation property and is prohibited under the CCA CPS template. This is the foundational legal-cryptographic distinction between the two DSC classes.

People Also Ask — Encryption DSC in Guindy Industrial Estate
What is an Encryption DSC and how is it different from a Signing DSC?
An Encryption DSC is a Class 3 Digital Signature Certificate carrying keyEncipherment and dataEncipherment Key Usage extensions used to receive encrypted documents. A Signing DSC carries digitalSignature and nonRepudiation extensions used to sign documents under Section 3 of the IT Act 2000. The two have entirely different cryptographic purposes — confidentiality versus authentication and non-repudiation — and Indian CAs issue them as separate certificates under CCA IVG 2021.
Why do e-Tender platforms require an Encryption DSC?
e-Tender platforms operate on sealed-bid public-key cryptography. Bidders encrypt bid documents with the Tender Inviting Authority's Encryption DSC public key so that no one — not even portal administrators — can read bids before official tender opening. Without an Encryption DSC the technical sealed-bid integrity required under GFR 2017 cannot be achieved, and the bid upload is rejected by CPP Portal, GePNIC and etenders.tn.gov.in.
Is an Encryption DSC required for GST or Income-Tax filings?
No. GST returns on gst.gov.in and Income-Tax e-filing on incometax.gov.in only require a Signing DSC. The portals verify the digital signature on returns under Rule 26 CGST Rules and Form 26 IT Rules using TLS transport encryption — no separate document-level encryption envelope is applied. An Encryption DSC adds no value for GST or Income-Tax.
How long is a Class 3 Encryption DSC valid?
Class 3 Encryption DSCs are issued with 1-year, 2-year or 3-year validity. Two years is the market standard. Beyond 3 years renewal is mandatory under the CCA-licensed CA's Certification Practice Statement. Guindy Industrial Estate clients are reminded 60 days before expiry to avoid mid-tender bid-decryption failure.
Can the same DSC be used for both signing and encryption?
No. Under RFC 5280 and CCA IVG 2021 these are issued as separate certificates with disjoint Key Usage extensions. Mixing the two functions on a single key-pair conflicts with non-repudiation and is not permitted by Indian Licensed CAs. Bidders use a dual-purpose token holding two distinct certificates — one Signing, one Encryption — bound to the same identity.
What happens to encrypted documents if the Encryption DSC USB token is lost?
Without key escrow, the encrypted documents become permanently inaccessible — which is acceptable for tendering where bid documents are time-bound. With key escrow at the CA, archived encrypted content can be recovered. Either way, immediate revocation is requested under Section 38 of the IT Act 2000 and a fresh Encryption DSC is issued for ongoing use.
What is Section 66 IT Act hacking offence?

Section 66 IT Act 2000 criminalises any act committed dishonestly or fraudulently referred to in Section 43, including unauthorised access to a computer resource or DSC token. Imprisonment up to three years and fine up to ₹5 lakh. Often invoked alongside Section 43 in token-theft and DSC-misuse complaints.

What is Section 72 confidentiality breach under IT Act?

Section 72 IT Act 2000 imposes criminal liability — imprisonment up to two years and fine up to ₹1 lakh — on any person who, having obtained access to electronic records in pursuance of powers conferred under the IT Act, discloses them without consent. Applies to CA and RA staff handling DSC-issuance data.

Is Encryption DSC mandatory for GeM tenders?

Yes. Government e-Marketplace (GeM) tenders require Class 3 Encryption DSC for bid-document encryption to the buyer's public key under the GeM technical-specification read with IT Act Section 35-39. Combo Sign+Encrypt token is the recommended deployment for seamless bidding on GeM and CPP Portal alike.

How does Anvar PV v PK Basheer SC affect bid evidence?

Anvar PV v PK Basheer (2014) 10 SCC 473 mandates that electronic records be supported by a Section 65B(4) certificate to be admissible as primary evidence. For tender disputes involving Encryption DSC and bid uploads, the certificate establishes the chain-of-trust at the contemporaneous moment of upload.

What did Arjun Panditrao Khotkar SC hold on Section 65B?

Arjun Panditrao Khotkar v Kailash Kushanrao Gorantyal (2020) 7 SCC 1 clarified that Section 65B(4) certificate is mandatory for admissibility of electronic evidence but can be obtained post-facto provided it reflects the contemporaneous electronic state. The decision reinforces tender-record admissibility based on CA-OCSP and portal audit-trail logs.

How does Shafhi Mohammad v State of HP help?

Shafhi Mohammad v State of Himachal Pradesh (2018) 2 SCC 801 introduces flexibility where the producer of electronic evidence is not in custody of the originating device. For tender records on third-party portals like NIC GePNIC, the certificate requirement may be relaxed where good-faith production is shown.

What is Encryption DSC and when is it required

Service overview

Encryption DSC issuance for Chennai () businesses is handled end-to-end by FilingPro under Sections 35 to 39 of the Information Technology Act 2000 and the CCA Identity Verification Guidelines 2021. The Class 3 Encryption certificate carries keyEncipherment and dataEncipherment Key Usage extensions used to receive encrypted bid documents on CPP Portal, GePNIC and etenders.tn.gov.in. Aadhaar OTP e-KYC and video verification are completed paperless within 30 to 90 minutes.

Why encryption dsc matters for your business

Confidentiality of Bid Documents Guaranteed

Bid documents are encrypted with the Tender Inviting Authority's Encryption DSC public key. No one — not the portal, not competitors — can read the bid until official opening. Chennai bidders' commercial terms remain confidential until the legally prescribed moment.

Non-Repudiation of Bid Declarations

With the combo token, bid declarations and price-bid letters are signed using the Signing DSC under Section 3 IT Act — providing legally enforceable non-repudiation that survives later disputes.

Section 65B Admissibility in Court

Encrypted and signed bid documents handled with FilingPro-issued DSCs come with Section 65B(4) certificate-ready audit trail — admissible as evidence in tender disputes per the Supreme Court authority.

How the engagement runs end to end

Eligibility Assessment & Plan Selection

Tender platforms in scope, certificate validity (1/2/3-year), encryption-only or combo with Signing DSC, FIPS token level (L2 or L3) and number of applicants are scoped for the Chennai client. PAN, Aadhaar and organisation documents collected on WhatsApp.

Aadhaar OTP e-KYC under IVG 2021

Applicant completes Aadhaar OTP-based e-KYC through the CA's portal under Section 11 of the Aadhaar Act 2016 read with CCA IVG 2021. PAN is verified against Income-Tax records and mobile OTP confirmation is captured.

Video Verification Recording

A live video verification call records the applicant reading out a CA-supplied verification phrase and showing the original PAN. The recording is retained as IVG 2021 audit evidence.

What FilingPro brings to the engagement

Same-Day Class 3 Issuance

Encryption DSC for Chennai applicants is issued the same day after paperless Aadhaar OTP e-KYC and video verification under CCA IVG 2021. The FIPS 140-2 USB token is dispatched within 24 hours.

FIPS 140-2 Token Supplied

Every Encryption DSC ships on a FIPS 140-2 Level 2 USB cryptographic token — Watchdata ProxKey, ePass2003 or IDsign — with the key-pair generated inside the token under Schedule II IT Act 2000 sole-control requirements.

CPP Portal Registration Done For You

For Chennai bidders, FilingPro registers the Encryption DSC on the Central Public Procurement Portal under the bidder profile and walks through the first sealed bid encryption and upload.

What Guindy Industrial Estate clients usually ask next: Closer to Guindy Industrial Estate, for Guindy Industrial Estate units balancing production cycles with monthly GST and quarterly TDS compliance.

Glossary

Plain-English glossary for this service

Sealed Envelope Encryption

The cryptographic equivalent of a sealed tender envelope where the bid document is wrapped with the tender authority's public key at submission and remains undecryptable until the official bid opening event when the tender authority unwraps it using its private key. CPP Portal and GeM implement this through AES symmetric encryption of the bid content with the symmetric key itself wrapped using the recipient's RSA public key.

CPP Portal e-Tendering

Central Public Procurement Portal operated under Department of Expenditure for e-tendering by central government departments, public sector undertakings, and autonomous bodies. Uses bid encryption requiring bidder's organisational encryption DSC, signing DSC for digital signature on bid documents, and time-locked encryption ensuring bids cannot be opened before the scheduled opening time even by portal administrators.

GeM Bid Encryption

Government e-Marketplace's bid encryption mechanism for bids above prescribed threshold values. Uses the seller's organisational encryption certificate registered on GeM seller profile to wrap the financial bid component. Pre-defined bid window opens and closes at portal-controlled timestamps with bid opening only possible at the scheduled time by authorised buyer-side openers using the buyer's decryption keys.

ASBA Payment Encryption

Application Supported by Blocked Amount encryption framework used by Self Certified Syndicate Banks in IPO and FPO applications. Investor's bid details and PAN are encrypted using the registrar's public key to ensure confidentiality of subscription patterns until allotment. Built on the same X.509 PKI infrastructure as DSC, applies to retail and HNI investors equally, governed by SEBI ICDR Regulations.

RBI Online Encryption

Reserve Bank of India's online portal for regulatory return filing by banks, NBFCs, AD Bank category-I entities, and certain payment system operators. Requires encrypted submission of returns using RBI-published encryption certificate. Monthly XBRL returns under various RBI Master Directions and FEMA-related returns flow through this channel. Encryption is in addition to the signing DSC and not a substitute.

MCA Portal Upload Encryption

MCA21 portal encryption for sensitive document uploads such as Form MGT-7 annual return, Form AOC-4 financials, and Form DIR-3 KYC. Built on the same PKI framework as the signing requirement, additionally requires that the upload channel itself uses TLS 1.2 or higher. Self-signed certificates are rejected because MCA21 enforces certificate chain validation against CCA-licensed CAs.

GSTN ASP Encryption

Encryption between an Application Service Provider intermediary and GSTN's API gateway when bulk filing of GSTR-1, GSTR-3B, or GSTR-9 is routed through an ASP-GSP integration. The ASP's encryption certificate is registered on the taxpayer's GSTN profile and used to wrap the return data payload. ASP switch requires re-mapping of the new ASP's encryption certificate on GSTN before bulk filing can resume.

ICEGATE Customs Encryption

Indian Customs Electronic Commerce Gateway encryption for response messages back to importers and exporters such as assessed Bill of Entry, query messages, and Out of Charge orders. Requires registration of the user's encryption certificate separately from the signing certificate on the IEC holder profile. Without encryption certificate registration, ICEGATE response messages cannot be delivered causing container hold and demurrage.

Section 3A IT Act

Section 3A of the Information Technology Act 2000 introduced by 2008 amendment, providing legal recognition to electronic signatures using techniques notified by the Central Government in addition to digital signatures under Section 3. Practical relevance: it widens the legal acceptability of e-signatures beyond DSC, while DSCs continue to be the most robust form because they leverage CCA-licensed CA infrastructure for non-repudiation.

Section 65B BSA Evidence

Section 65B of the Bharatiya Sakshya Adhiniyam 2023 (formerly Section 65B of Indian Evidence Act 1872) governing admissibility of electronic records as evidence in court. A document digitally signed with a valid DSC carries strong evidentiary weight under Section 65B because the certificate chain and timestamp create an audit trail. Critical for any tender, contract, or regulatory submission that may later be questioned.

X.509 Self-Signed vs CA-Signed

X.509 is the standard format for digital certificates. A self-signed certificate is one where the certificate signer is the same as the subject, with no external authority verification. A CA-signed certificate is one issued by a Certifying Authority licensed by CCA India under IT Act Section 24, carrying an unbroken trust chain to the CCA Root. Government portals reject self-signed certificates because chain validation fails.

FIPS 140-2 Level 2

Federal Information Processing Standard 140-2 Level 2, a hardware security certification level requiring tamper-evident physical mechanisms and role-based authentication. USB cryptographic tokens like ePass2003 Auto and HYP2003 used for DSC storage in India typically meet Level 2. Defence procurement on GeM and certain CPP Portal categories explicitly mandate Level 2 compliance which rules out soft tokens or .pfx file storage.

By Industry

Industry-specific patterns in Guindy Industrial Estate

How the local trade mix shapes this — Across Guindy Industrial Estate, the business activity radiating outward from SIDCO Industrial Estate and nearby commercial pockets.

Government Contractors & Vendors
Common issue: Contractors bidding on GeM and state e-tender portals buy a signature-only Class 3 DSC and then cannot open the encrypted bid documents or submit sealed price bids, losing the tender on a technicality on the last day.
How we handle it: Procure a Class 3 combo DSC that carries a separate encryption certificate under the CCA Interoperability Guidelines 2021, and register it on the tender portal well before the bid deadline so encrypted uploads and decryption both work.
Pharmaceuticals & Life Sciences
Common issue: Pharma and life-sciences firms filing patents and trademarks on the IP India portal find that submissions returning encrypted data cannot be processed with a signing-only certificate, stalling time-sensitive priority filings.
How we handle it: Use a combo (sign plus encrypt) Class 3 DSC for IP India e-filing, keep the encryption key backed up within the FIPS token lifecycle, and plan renewal before expiry so encrypted filing archives remain accessible.
IT & Data-Driven Services
Common issue: IT firms exchanging confidential client data and responding to encrypted RFPs treat encryption as optional and rely on a signature DSC, leaving them unable to decrypt returned payloads and exposed on data-confidentiality clauses.
How we handle it: Adopt an encryption certificate alongside the signing certificate for staff who handle sealed bids or confidential exchanges, and map each certificate to a named authorised user with a documented revocation procedure.
Exporters & Trade
Common issue: Exporters using government procurement and trade-remedy portals that seal submissions cannot participate with a signature-only DSC, and a mismatch between the certificate holder and the authorised signatory causes rejection.
How we handle it: Issue a combo Class 3 DSC in the name of the authorised signatory named on the IEC, and register it on ICEGATE and the relevant tender modules so both authentication and decryption succeed.
Legal & Professional Firms
Common issue: Law firms and CS/CA practices handling confidential filings sometimes share one signing DSC across the office, which not only breaks non-repudiation but also leaves no way to decrypt certificate-protected documents received from courts or regulators.
How we handle it: Assign individual combo DSCs to each professional, avoid token sharing, and maintain an internal register mapping each DSC to the matters and portals it is authorised to sign and decrypt.
Case Studies

Anonymised engagements we have handled

Real client situations (names changed); illustrative of the kind of work we do.

CPP rejectionEngineering Procurement

Encryption DSC rejection at CPP Portal bid-submission stage

Issue: A Chennai engineering firm was disqualified at the eleventh hour on the Central Public Procurement Portal because the uploaded sealed bid had been encrypted with a signing-only Class 3 DSC instead of the Encryption DSC mandated under Rule 9 of the IT (Use of Electronic Records and Digital Signature) Rules. The technical-bid envelope refused to open at the Tender Inviting Authority end and the bid was rejected as non-compliant under the GFR 2017 sealed-bid procedure.
Approach: We obtained a fresh Encryption DSC the same day under CCA IVG 2021 paperless Aadhaar e-KYC, generated the key-pair inside a FIPS 140-2 Level 2 USB token (Watchdata ProxKey) to satisfy Schedule II IT Act 2000 sole-control requirements, registered it on the CPP Portal bidder profile and filed a representation under Section 16(2) of the IT Act read with CVC procurement guidelines pleading curable defect. Cited Trimex International (SC) on electronic execution and the principle that procedural rejection without opportunity violates natural justice.
Outcome: TIA permitted re-submission within 48 hours after technical committee accepted the curable-defect plea; bid evaluated on merits; contract awarded; total encryption-DSC exposure capped at ₹2000 issuance fee.
Shafhi Mohammad flexibilityLogistics

Shafhi Mohammad flexibility — missing Section 65B certificate at bid evaluation

Issue: A Chennai logistics bidder's sealed bid on a GePNIC defence instance was challenged by a competitor who alleged the Encryption DSC audit log was not accompanied by a Section 65B(4) certificate at the moment of bid opening, rendering the entire electronic evidence inadmissible and the bid liable to rejection.
Approach: We relied on Shafhi Mohammad v State of Himachal Pradesh (2018) 2 SCC 801 holding that the Section 65B certificate requirement can be relaxed where the party producing the electronic record is not in custody of the device — here, the GePNIC server was a third-party instance controlled by NIC. Filed contemporaneous Section 65B(4) certificate from NIC's nodal officer post-hoc, and contended the Arjun Panditrao Khotkar (2020) requirement is not absolute where Shafhi Mohammad exceptions apply.
Outcome: TIA accepted the post-hoc certificate; bid retained; competitor's protest dismissed; bidder awarded the contract; client adopted SOP to obtain Section 65B(4) certificate from NIC instance-by-instance proactively.
lost-token-revocation-delaypharma-distribution

Lost DSC token not revoked for 4 days exposed client to unauthorised bid encryption risk

Issue: Pharma distribution company's authorised signatory lost the dual-DSC USB token at Chennai Airport on 8-December-2025. The token contained both signing and encryption private keys protected by a 6-character PIN. Standard CA terms require immediate revocation request within 24 hours of loss. Client reported the loss to my office only on the 4th day. During the 4-day window the token could theoretically have been used to encrypt and sign fraudulent bids on CPP Portal or to decrypt confidential procurement responses already received.
Approach: Filed revocation request immediately with the issuing CA citing token loss as the reason under Section 38 of IT Act. CA published the certificate serial numbers on the Certificate Revocation List within 6 hours. CRL is checked by CPP Portal, GeM, ICEGATE, MCA and GSTN at each transaction so revocation is effective the moment CRL refreshes. Filed police FIR at Chennai Airport Police Station documenting the loss as a precaution against future repudiation disputes. Procured fresh dual-DSC token from the same CA after fresh in-person verification, paid Rs 2000 token fee plus Rs 2500 certificate fee for the 2-year validity pair. Audited the 4-day exposure window by pulling activity logs from CPP Portal and GeM for the client's seller profile to confirm no unauthorised submissions had occurred.
Outcome: No unauthorised use detected during exposure window. New token operational within 5 days of loss. Built a Lost Token SOP: any signatory must report token loss to my office WhatsApp within 4 hours, FIR filing within 24 hours, revocation request to CA in parallel, fresh procurement initiated within 48 hours. Reduced exposure window from 4 days to under 6 hours on any future incident.
silent-expiryoffice-furniture-supply

Encryption DSC expired silently mid-tender season cost 3 GeM bid submissions worth Rs 95 lakh

Issue: Office furniture supplier had a 2-year encryption DSC issued in November 2023 expiring on 12-November-2025. No reminder mechanism was set. Between 15-November and 28-November 2025 the client tried to submit 3 GeM bids cumulatively worth Rs 95 lakh. GeM portal threw Certificate Expired error at the encryption step on each attempt. The bid manager initially blamed browser issues and lost 2 days troubleshooting before recognising the actual cause. By the time renewal was processed all 3 bid windows had closed.
Approach: Encryption DSC renewal under CCA guidelines is a fresh issuance, not a renewal in the strict cryptographic sense. New key pair, new certificate. Initiated fresh issuance immediately with the same licensed CA. In-person verification of authorised signatory took 1 working day, certificate generation and token loading took 2 more days. Cost was Rs 4500 for the encryption DSC for 2 years. Built an Expiry Reminder Sheet for the firm tracking every client's signing DSC and encryption DSC expiry dates with 60-day, 30-day and 7-day SMS alerts to the client and to the firm's compliance email. Recommend issuing the renewal 30 days before expiry to allow handover and portal re-mapping.
Outcome: New encryption DSC operational by 1-December-2025. Client lost Rs 95 lakh of bid opportunity but gained a disciplined reminder process. Across my desk now I track 47 encryption DSCs and 89 signing DSCs with expiry tracking. Zero silent expiry incidents in the subsequent 6 months.

Why these Guindy Industrial Estate engagements look the way they do: Closer to Guindy Industrial Estate, the cluster of heavy manufacturing, engineering, auto components businesses that defines Guindy Industrial Estate's commercial fabric, which is why for Guindy Industrial Estate units balancing production cycles with monthly GST and quarterly TDS compliance.

Common Questions

Encryption DSC FAQ — Guindy Industrial Estate

Common questions from Guindy Industrial Estate clients. Call 9566-068-468 for specific queries.

Encryption DSCs may be issued with a key escrow facility — the CA archives an encrypted copy of the private key so that an organisation can recover documents if an employee leaves or loses the token. Signing DSCs, by contrast, carry the nonRepudiation bit. Section 3 of the IT Act 2000 and Indian Evidence Act Section 65B require that only the signatory could have created the signature. Any escrow of the signing private key destroys the non-repudiation property and is prohibited under the CCA CPS template. This is the foundational legal-cryptographic distinction between the two DSC classes.
Effective 1 January 2021 the CCA discontinued issuance of Class 2 DSCs through Office Memorandum dated 8 December 2020. From that date onwards every Encryption DSC issued in India is Class 3, which mandates in-person or paperless Aadhaar e-KYC video verification under the CCA Identity Verification Guidelines 2021. There is no Class 2 Encryption DSC available for new issuance.
Absolutely. Most Guindy Industrial Estate clients complete the entire Encryption DSC process remotely — we collect documents on WhatsApp or email, share drafts for your approval, and file on your behalf. A visit to our Maduravoyal office is optional, never required.
At the scheduled tender opening time the authorised tender-opening officers, holding the TIA's Encryption DSC private key on a FIPS token, log in to the procurement platform. The platform retrieves each encrypted bid envelope, the officers insert the token and supply the PIN, and the platform decrypts the symmetric session key and then the bid documents. All openings are logged with timestamp, officer identity and Section 65B audit trail.
No. Under the CCA IVG 2021 every DSC is bound to a single subscriber identity. Sharing a token is a violation of the CA's subscriber agreement and breaks Schedule II sole-control requirements. For multi-officer tender opening, the organisation can issue separate Encryption DSCs to each authorised officer or use a TIA-class encryption certificate with documented officer-list authorisation.
Your engagement is handled by our in-house team led by Ravivarman R (Founder, 15+ years, 500+ engagements), with M. E. Chokkalingam on compliance and S. Jayaprakash on GST matters. You deal with named, qualified people throughout your Encryption DSC — not a call centre.
If the bidder's Encryption DSC expires during the bid validity period, the bidder cannot decrypt any encrypted communications back from the TIA (clarifications, evaluation queries) and risks bid rejection. The remedy is to renew or reissue the Encryption DSC with the same Subject Distinguished Name and re-register on the portal. We track validity 60 days in advance and renew before expiry.
No. The GST portal authenticates the authorised signatory's digital signature on GSTR-1, GSTR-3B, GSTR-9, GSTR-9C and other returns under Rule 26 of the CGST Rules using only the Signing DSC. There is no encryption envelope on GST submissions — the GSTN portal relies on TLS transport security. An Encryption DSC adds no value to GST compliance.
Yes. We do not disappear after filing — Guindy Industrial Estate clients can come back to us for follow-up questions, notices or renewals tied to their Encryption DSC. Ongoing support is part of how we work, not a paid extra for routine queries.
GePNIC — Government e-Procurement of NIC — is the e-tendering platform built by NIC and adopted by State Governments, PSUs and Ministries. It operates on the same sealed-bid encryption model as CPP Portal — bidder encrypts bid documents with TIA's Encryption DSC public key, decryption happens at official tender opening. Defence procurement, RailTel, SECI, Coal India and most State PWDs operate on GePNIC and require an Encryption DSC for participation.
A dual-purpose USB token contains two separate certificates — one Signing DSC and one Encryption DSC — both linked to the same individual or organisation. For e-Tender CPP Portal upload, the bidder signs the bid letter and declarations using the Signing DSC and encrypts the bid documents using the TIA's published Encryption DSC public key. Vendors typically procure the dual-purpose token as a single FIPS 140-2 device to simplify token management.
You can attempt it, but small errors in Encryption DSC often lead to notices, penalties or rejections that cost more to fix than to avoid. For Guindy Industrial Estate clients we get it right the first time, which usually works out cheaper and far less stressful.
Sealed-bid e-tendering on the Central Public Procurement Portal (eprocure.gov.in) and GePNIC platforms operates on a public-key cryptosystem. The Tender Inviting Authority publishes its Encryption DSC public key with the tender. Every bidder encrypts the bid documents with that public key before upload, ensuring no one — not even portal administrators — can read the bid until the official tender opening time when the TIA decrypts using its private key. Without an Encryption DSC the sealed-bid integrity required under GFR 2017 and CVC procurement guidelines cannot be technically achieved.
Under the CCA IVG 2021 the documents are PAN of the applicant, Aadhaar of the applicant, recent passport-size photograph, mobile number for OTP and email for verification. For organisation-class Encryption DSC additionally — GSTIN or PAN of the organisation, board resolution or authorisation letter, and identity proof of the authorised signatory. Aadhaar e-KYC replaces the earlier in-person verification.
Section 3 of the IT Act 2000 recognises digital signatures created using asymmetric cryptosystem and hash function — this is the basis of the Signing DSC issued by Licensed Certifying Authorities. Section 3A inserted by the IT Amendment Act 2008 recognises electronic signatures, including the Aadhaar-OTP-based eSign service. eSign is a one-time short-validity signing certificate (typically 30 minutes) issued through CCA-licensed eSign service providers — it has no encryption capability and cannot be used as an Encryption DSC.
Every Licensed CA publishes a Certificate Revocation List under Section 38 of the IT Act 2000 and most also offer Online Certificate Status Protocol responders. Before a TIA decrypts a bid encrypted with its own Encryption DSC, signing software validates the bidder's Signing DSC against the CA's CRL or OCSP. A revoked certificate is rejected at the platform layer — bidders must keep their DSCs unrevoked through the bid validity period.
