Class 3 Digital Signature Certificate (DSC) Issuance & USB Token Services in Raipur
Class 3 Digital Signature Certificate (DSC) Issuance & USB Token Services in Raipur— Overview & Compliance
Chartered Accountancy advisory and audit services in Raipur, Chhattisgarh & Kalahandi, Odisha. Partner-led verification ensuring full statutory compliance under applicable laws.
A Class 3 Digital Signature Certificate (DSC) is the highest level of cryptographic identity assurance mandated by the Controller of Certifying Authorities (CCA), Ministry of Electronics and Information Technology (MeitY), Government of India, under the Information Technology Act, 2000.
Following the deprecation of Class 2 certificates, Class 3 DSCs with dual-factor video verification have become mandatory for corporate directors, tax audit filers, government contractors, exporters, and business entities executing filings on the MCA V3 Portal, Income Tax E-Filing Portal, GST Portal, and Central/State E-Procurement Tenders.
At Rabi Agrawal & Associates, our Raipur Head Office provides paperless, same-day Class 3 DSC issuance, cryptographic USB token supply (HYP2003 / ePass2003), driver configuration, and portal PKI middleware setup for companies, LLPs, firms, and contractors across Chhattisgarh and Odisha.
Class 3 DSC Framework under Information Technology Act, 2000
Digital Signature Certificates carry legal recognition under Section 5 and Section 15 of the IT Act, 2000, making a digitally signed electronic document as legally binding as a handwritten physical signature. Modern Class 3 certificates utilize 2048-bit RSA encryption and SHA-256 hashing algorithms to ensure message integrity, non-repudiation, and sender authentication.
- CCA Compliance: Issued strictly through licensed Certifying Authorities (CAs) including eMudhra, Capricorn, Pantagon, Vsign, and SignX.
- Mandatory Video Verification: Verification requires a brief video recording by the applicant holding original identity documents and stating a unique OTP.
- Paperless Issuance: Processed using Aadhaar Offline XML, PAN-based verification, or organizational document validation, eliminating physical paper submissions.
- Hardware Token Mandate: Cryptographic private keys must reside inside an approved hardware USB token and cannot be exported or copied.

Step-by-Step Issuance & Verification Workflow
We deliver rapid, paperless Class 3 DSC issuance at our Raipur office or remotely:
Hardware USB Tokens & PKI Middleware Setup (HYP2003 / ePass2003)
Security regulations prohibit storing digital signatures directly on computers or standard flash drives. They must reside on secure cryptographic USB tokens:
- FIPS 140-2 Level 2 Tokens: We supply genuine, tamper-evident cryptographic tokens including HYP2003 (Auto-run), ePass2003, and Watchdata PRO, featuring hardware-level PIN protection.
- Token Driver & CSP Installation: Installing requisite Token CSP (Cryptographic Service Provider) drivers and PKI middleware on Windows 10/11 environments.
- Java & Browser Middleware Alignment: Configuring Java Security Settings, WebSign utilities, and emBridge / emSigner services required by MCA V3 and e-Tendering portals.
- Token PIN Management: Setting up custom, secure User PINs and Admin PINs, and guiding clients on pin lockout recovery.
Validity Period, Renewal & Security Guidelines (IT Act 2000)
Important compliance, renewal, and security rules governing Class 3 Digital Signatures:
- Validity Options: Available in 1-year, 2-year, or 3-year validity periods. Renewal can be initiated up to 30 days prior to expiry.
- Token Reusability: Existing FIPS 140-2 USB tokens can be re-used for DSC renewal, reducing electronic waste and issuance costs.
- Revocation Protocol: Immediate certificate revocation is initiated in the event of token loss, compromise of PIN, or change in organizational authorization.
- Confidentiality & PIN Protection: Under the IT Act, 2000, the DSC owner is personally responsible for signatures executed using their certificate. Token PINs must never be shared or disclosed.
