Class 3 Digital Signature Certificates issued in Mogappair West 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 Mogappair West 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 Mogappair West 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.

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.
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.
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.
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.
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.
The UNCITRAL Model Law on Electronic Signatures was adopted by the United Nations Commission on International Trade Law in 2001 as a framework instrument to guide states in adopting legislation on electronic signatures. The Model Law establishes a functional-equivalence approach: an electronic signature satisfies a legal requirement for a signature if it is sufficiently reliable for the purpose for which the data message was generated, with reliability assessed against five criteria including the link of the signature to the signatory, the signatory's control over the signature-creation data, and detectability of subsequent alterations. India is not a formal adherent to the Model Law but the IT Act 2000 substantially reflects its principles, having been drafted in parallel with the development of the Model Law and the predecessor UNCITRAL Model Law on Electronic Commerce 1996. The compatibility provides the substantive basis for cross-recognition of India Class 3 DSCs in Model-Law-adopting jurisdictions.
The European Union's electronic identification and trust services framework is established under Regulation (EU) 910/2014 of the European Parliament and of the Council of 23-07-2014 on electronic identification and trust services for electronic transactions in the internal market, commonly referred to as the eIDAS Regulation. eIDAS establishes a three-tier taxonomy of electronic signatures: Electronic Signature (the lowest tier, broadly equivalent to any electronic data attached to an electronic record), Advanced Electronic Signature (AES, which uniquely identifies the signatory and is linked to the signed data such that any subsequent change is detectable), and Qualified Electronic Signature (QES, an AES created by a qualified signature creation device and based on a qualified certificate). Under Article 25 of eIDAS, a QES has the equivalent legal effect of a handwritten signature throughout the European Union. The Indian Class 3 DSC corresponds taxonomically to AES under eIDAS, not QES.
In the United States, electronic signatures are governed at the federal level by the Electronic Signatures in Global and National Commerce Act (ESIGN Act) of 2000, which establishes the general rule that a signature, contract or record relating to a transaction in or affecting interstate or foreign commerce shall not be denied legal effect, validity or enforceability solely because it is in electronic form or because an electronic signature was used in its formation. The ESIGN Act is supplemented at the state level by the Uniform Electronic Transactions Act (UETA), adopted in 1999 by the Uniform Law Commission and enacted in some form by forty-seven of the fifty states (with New York, Illinois and Washington having parallel state legislation). The US framework is technology-neutral and does not impose a specific cryptographic standard, making it easier than eIDAS for an India Class 3 DSC to be accepted in US commercial transactions on a reliability-based assessment.
