Class 3 Digital Signature Certificates issued in Sri Saraswathi Nagar Maduravoyal 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 Sri Saraswathi Nagar Maduravoyal 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 Sri Saraswathi Nagar Maduravoyal 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.
Yes. A foreign national or NRI can obtain a Class 3 DSC using an apostilled or consular-attested passport and address proof, with video verification. Indian PAN is required where the DSC is used for MCA or Income-tax filings; DIN-linked director DSCs additionally need the PAN or passport on record with the MCA.
Yes. Simply holding the token is not enough — each portal requires a one-time registration mapping the DSC to your PAN or DIN and role. On MCA21 V3 the director registers the DSC against the DIN; on GST the authorised signatory registers it against the GSTIN before any DSC-signed filing is accepted.
Under the CCA Identity Verification Guidelines, a short applicant-recorded video stating name and consent is mandatory for paperless Aadhaar e-KYC issuance. It is the step most often failed when the audio is unclear or the applicant reads a different script than instructed by the Certifying Authority.
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.

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.
Section 5 of the IT Act 2000 provides that where any law requires that a document be signed, the requirement is satisfied if the document is authenticated by means of a Digital Signature affixed in such manner as may be prescribed. Section 85B of the Indian Evidence Act 1872 (inserted by the IT Act 2000 and renumbered by the Bharatiya Sakshya Adhiniyam 2023) creates a presumption that a secure electronic record has not been altered since the date on which the digital signature was affixed. Section 67A of the Bharatiya Sakshya Adhiniyam 2023 (corresponding to the earlier Section 67A of the Evidence Act) requires that a person seeking to rely on an electronic record produce a certificate from the CA verifying the signature. Together, these provisions establish digital signatures as functionally equivalent to handwritten signatures for evidentiary purposes in Indian courts.
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.
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.
A Class 3 Combo certificate combines both signing and encryption capabilities in a single token, often through two physically-separate certificate-and-key-pairs stored on the same hardware token. Combo certificates are required for use-cases that involve both signing and confidentiality — notably e-tendering on CPPP, GeM, IREPS and several state e-procurement portals where the bidder signs the bid document with the signing certificate and the procuring entity encrypts feedback to the bidder using the encryption certificate. The ONDC seller-node TLS-mutual-authentication architecture similarly requires a Combo certificate. Combo certificates carry a higher unit cost than signing-only or encryption-only, but the practical convenience of a single token covering both use-cases drives most corporate procurement towards Combo.
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.
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 India PKI profile specifies RSA as the primary public-key cryptographic algorithm, with a minimum key-length of 2048 bits for subscriber certificates issued from 01-01-2014 onwards. The CCA's 2022 Cryptographic Guidelines updated the recommended key-length to 3072 bits for new certificates issued from 01-01-2025, with 2048-bit certificates issued before that date remaining valid for their natural validity period. The signature algorithm on subscriber certificates is currently sha256WithRSAEncryption, replacing the sha1WithRSAEncryption that was phased out by 01-01-2016 following the SHA-1 deprecation timeline coordinated internationally by the CA/Browser Forum. Elliptic Curve Cryptography (ECC) certificates under sha256ecdsa are permitted under the India PKI profile but are not yet widely deployed because most Indian government portal validators are RSA-only in practice.
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.
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.
Section 38 of the IT Act 2000 confers the power to revoke a Digital Signature Certificate on the subscriber and on the issuing Certifying Authority. The subscriber can request revocation at any time through the issuing CA's revocation portal, typically by submitting a signed revocation request with reasons (compromise of private key, loss of token, change of subscriber's identifying details or termination of employment of the named signatory). The CA can revoke a certificate suo motu if it discovers that the certificate was issued on the basis of inaccurate or false information, or if the subscriber has materially breached the subscriber agreement. Section 38 revocation is publicised through the CA's Certificate Revocation List (CRL) and Online Certificate Status Protocol (OCSP) responder, which together enable any third-party verifier to determine the revocation status of a specific certificate in real time.
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.
