Class 3 Digital Signature Certificates issued in Vanagaram-Ambattur Road under Section 35 of the IT Act 2000 by CCA-licensed Certifying Authorities — paperless Aadhaar OTP e-KYC, FIPS 140-2 USB token and 2-year standard validity. Class 2 DSC deprecated 1-Jan-2021.
Class 3 individual DSC for Vanagaram-Ambattur Road directors, partners and proprietors — used for MCA DIR-3 KYC, SPICe+ incorporation, Income Tax ITR signing under Section 140 of the Income-tax Act and personal e-Tendering. Same-day Aadhaar e-KYC issuance.
Class 3 organisation DSC for Vanagaram-Ambattur Road companies and LLPs — used for GST authorised signatory under Rule 26 CGST Rules, TRACES Form 24Q/26Q TDS filing under Section 200(3) Income-tax Act, IceGate Customs and DGFT IEC. Authorisation letter and CIN/GSTIN proof required.
CCA Identity Verification Guidelines 2021 permit three modes — paperless Aadhaar OTP e-KYC, video-based verification with original document display, and in-person verification before a CA-authorised officer. Choice depends on Aadhaar mobile linkage and applicant location.
A Class 3 DSC is a digital signature certificate issued under Section 35 of the IT Act 2000. After the CCA discontinued Class 2 certificates from 1 January 2021, Class 3 — with in-person or video identity verification — became the sole class issued for all statutory and commercial filings.
Yes. MCA21 V3 accepts only Class 3 DSCs for director and professional filings, and the GST portal requires a Class 3 DSC for companies and LLPs under Rule 26 of the CGST Rules 2017. Individuals and proprietors may use EVC, but a DSC is still required for many forms.
A signature DSC only signs documents for authentication and non-repudiation. A combo DSC adds a separate encryption certificate to decrypt data returned by a portal — needed mainly for government e-tenders (GeM, CPPP) and IP India trademark filings. Most tax filers need only the signature type.
With Aadhaar-based paperless e-KYC and video verification, a Class 3 DSC is typically issued the same working day. Delays arise only when the mobile number is not linked to Aadhaar or the applicant's name mismatches between PAN and Aadhaar.
For Aadhaar e-KYC: PAN, Aadhaar-linked mobile for OTP, a passport-size photo and a short video verification. For paper-based KYC: self-attested PAN and address proof attested by a gazetted officer or banker. The applicant's mobile and email must be their own.
A Class 3 signature DSC costs approximately ₹1,200–₹1,500 one-time for a 2-year certificate including the FIPS 140-2 Level 2 USB token, Aadhaar e-KYC and video verification. A combo (sign + encrypt) DSC costs approximately ₹1,800–₹2,500 for the same term.

A Digital Signature Certificate (DSC) is an electronic credential issued by a licensed Certifying Authority (CA) that binds a public-key cryptographic key-pair to the identity of a subscriber, enabling the subscriber to digitally sign electronic records with legal effect equivalent to a handwritten signature. The Indian framework is established under the Information Technology Act 2000, which received Presidential assent on 09-06-2000 and was inspired by the UNCITRAL Model Law on Electronic Commerce 1996 adopted by the United Nations Commission on International Trade Law in resolution 51/162 of 16-12-1996. Sections 35 to 39 of the IT Act 2000 set out the framework for issuance, suspension and revocation of Digital Signature Certificates, while Section 17 establishes the office of the Controller of Certifying Authorities (CCA) as the apex regulator of the DSC ecosystem in India.
Historically, DSCs were issued in three classes — Class 1, Class 2 and Class 3 — corresponding to progressively higher levels of identity verification. Class 1 was issued on the basis of an email-address verification alone and was suitable for low-value transactions. Class 2 was issued on the basis of identity-document and address-document verification and was the workhorse certificate for income-tax e-filing, MCA21 and most government portals for over a decade. Class 3 has historically required in-person verification or video-verification with biometric authentication and was reserved for high-value transactions such as e-tendering and e-procurement. The CCA's Office Order of 28-12-2020 mandated the discontinuance of Class 2 DSC from 01-01-2021, leaving Class 3 as the single class of DSC for all use-cases. The transition was completed by mid-2021 with the entire ecosystem migrated to Class 3 by issuing CAs.
The IT (Amendment) Act 2008, which came into force on 27-10-2009, inserted Section 3A in the IT Act 2000 to recognise a broader category of electronic signature in addition to the Digital Signature Certificate based on asymmetric cryptography. Section 3A enables the Central Government to notify by rule any electronic signature technique that is reliable as defined in the section. The notification under Section 3A enabled the Aadhaar-based e-Sign service launched in 2015, under which a subscriber authenticates via Aadhaar OTP or biometric and a one-time certificate is issued for the immediate signing transaction. Class 3 DSC and e-Sign coexist as alternative authentication mechanisms, with Class 3 DSC being the preferred mode for multi-use and high-value transactions and e-Sign being the preferred mode for single-transaction citizen-facing workflows.
A Document Signer Certificate is a specialised variant of the Class 3 Organisation DSC, introduced by the CCA in 2017 to enable unattended bulk signing in enterprise workflows (digital invoice signing under the GST e-invoice framework, bulk certificate issuance by educational institutions, contract-signing automation in financial services). The Document Signer Certificate is issued in the name of the legal entity (not an individual signatory) and is stored on a Hardware Security Module (HSM) compliant with FIPS 140-2 Level 3 or equivalent, rather than on a USB cryptographic token. The HSM-based storage allows the certificate to be invoked programmatically without manual PIN entry, supporting high-volume signing throughput. The CCA's 2017 office order specifying this variant requires additional CA-level controls including HSM audit logging and segregation of duties between the certificate-administration team and the signing-operation team.
A Class 3 Signing certificate carries a key-usage extension limited to digitalSignature and nonRepudiation under RFC 5280, and is designed for the use-case where the subscriber needs to authenticate documents and electronic records by affixing a digital signature. The certificate's private key is used to compute the signature over a cryptographic hash of the document, and the public key (carried in the certificate itself) is used by the verifier to confirm authenticity and integrity. Signing-only certificates are sufficient for most government-portal use-cases including MCA21, GST, EPFO, ESIC, ICEGATE, and DGFT. They are typically the cheapest variant offered by issuing CAs, with one-year, two-year and three-year validity SKUs, and are the default recommendation for individual subscribers and small enterprises.
A Class 3 Encryption certificate carries a key-usage extension limited to keyEncipherment and dataEncipherment, and is designed for the use-case where the subscriber needs to receive confidential documents encrypted with their public key. The private key is used to decrypt incoming messages, and the public key is published in the CA's directory for senders to use as the encryption target. Encryption-only certificates are less common in standalone form because most subscribers also need signing capability, but they are required as a distinct credential in certain e-tendering workflows where the procuring entity encrypts the technical-bid documents to the bidder's public key for confidentiality during the pre-opening window. The corresponding cryptographic algorithm under the India PKI profile is RSA with PKCS#1 v1.5 or OAEP padding.
The Subject Distinguished Name on a Class 3 DSC is composed of mandatory and optional attributes specified in the India PKI profile. For an Individual DSC, the mandatory attributes include the subscriber's common name (CN), country (C=IN), state (ST), and may include a serial number to disambiguate same-name subscribers. For an Organisation DSC, additional mandatory attributes include the organisation name (O) and organisation unit (OU). The Subject Alternative Name (SAN) extension under RFC 5280 permits the inclusion of additional identifier types including email address, DNS name, IP address and otherName. The otherName field is used in the India PKI profile to carry sector-specific identifiers such as CDSCO licence number, RBI Certificate of Registration number, FSSAI FBO licence number and similar regulatory identifiers, enabling straight-through authentication on sector portals.
The CCA framework requires that the private key of a Class 3 DSC be stored on a hardware cryptographic token meeting FIPS 140-2 Level 2 (USB token) or Level 3 (HSM) certification under the US National Institute of Standards and Technology's Federal Information Processing Standard. Commonly available USB tokens in the Indian market include eMudhra ePass2003 Auto, Sify SafeNet eToken 5110, Watchdata ProxKey, HYP2003 and the more recent SafeNet eToken FIPS variants. The tokens are accessed via PKCS#11 (the Cryptographic Token Interface Standard under RSA Laboratories' Public-Key Cryptography Standards series, now maintained by OASIS) which provides a standard programming interface for cryptographic operations. The PKCS#11 driver for each token brand is provided by the issuing CA and must be installed before the token can be used on a Windows or macOS workstation.
The Class 3 DSC issued under the India PKI framework follows the X.509 v3 certificate format specified in ITU-T Recommendation X.509 (08/2005) and IETF RFC 5280. The X.509 v3 certificate is a structured data object containing the certificate's version, serial number, signature algorithm identifier, issuer (the issuing CA's Distinguished Name), validity period (notBefore and notAfter dates), subject (the certificate holder's Distinguished Name), subject public-key information (the algorithm and the public key itself), and a set of v3 extensions including key usage, extended key usage, certificate policies, CRL distribution points and authority information access. The certificate is itself signed by the issuing CA's private key, with the signature appended to the certificate body, allowing any verifier with access to the CA's public key to confirm the certificate's authenticity.
The Certificate Revocation List is a digitally-signed list of revoked certificate serial numbers published periodically (typically every twenty-four hours) by each issuing CA at a URL specified in the CRL Distribution Points extension of every subscriber certificate. The CRL format and update mechanics are governed by IETF RFC 5280. The Online Certificate Status Protocol (OCSP), specified in IETF RFC 6960, provides a real-time alternative to CRL: a verifier sends an OCSP query to the issuing CA's OCSP responder with a specific certificate serial number and receives an immediate signed response confirming the certificate's status as good, revoked or unknown. The India PKI profile requires every Class 3 DSC to carry both a CRL Distribution Points extension and an Authority Information Access extension pointing to the OCSP responder URL, enabling verifiers to choose the appropriate revocation-check mechanism for their workflow.
Section 37 of the IT Act 2000 provides for suspension of a Digital Signature Certificate as a temporary measure short of revocation. Suspension may be invoked by the CA on its own motion or on a request from the subscriber or any person authorised by the subscriber, where the circumstances warrant a temporary halt of the certificate's operational validity pending resolution of an issue (suspected compromise that is being investigated, dispute over the subscriber agreement, or processing of a change-of-particulars request). The suspended certificate appears on the CRL with a status of certificateHold and a specific OCSP response indicating suspension. If the underlying issue is resolved, the suspension may be lifted and the certificate restored to operational status. If the issue cannot be resolved, the suspension typically converts to a full revocation under Section 38.
Where the subscriber has reason to believe that the private key associated with the Class 3 DSC has been compromised (lost token, stolen token, suspected malware on the host machine, or exposure of the token PIN to an unauthorised person), the subscriber must immediately initiate revocation under Section 38 and notify the issuing CA. Most issuing CAs offer a twenty-four-hour helpline for emergency revocation initiation. The compromised-key protocol involves: (a) immediate revocation request on the CA's portal or helpline, (b) the CA's publication of the revoked serial number on the CRL and OCSP responder within twenty-four hours (typically much faster), (c) the subscriber's review of all documents signed during the compromise window to identify any unauthorised signings, and (d) procurement of a fresh certificate to restore signing capability.
