In India's rapidly digitizing economy, the Digital Signature Certificate (DSC) has become an indispensable tool for businesses and individuals alike.
It is the digital equivalent of a physical or handwritten signature, offering a higher level of security, authenticity, and legal validity for online transactions. Whether you're filing income tax returns, submitting a tender, or registering a company with the Ministry of Corporate Affairs (MCA), a DSC is no longer just an option-it's a necessity.
However, navigating the process of obtaining one can seem daunting. With various classes, providers, and verification methods, it's easy to feel overwhelmed.
This guide cuts through the complexity, providing a clear, step-by-step roadmap to securing your Digital Signature Certificate efficiently and effectively. We'll explore what a DSC is, why you need one, and the most streamlined methods to get yours, ensuring you're equipped for secure digital operations.
Key Takeaways
- 📌 What is a DSC? A Digital Signature Certificate (DSC) is a secure digital key, issued by a licensed Certifying Authority (CA), that validates your identity electronically.
It's essential for online filings, e-tendering, and legally binding digital documents in India.
- ⚖️ Legal Standing: DSCs are legally admissible under the Indian Information Technology Act, 2000, carrying the same weight as a physical signature.
- 🔑 Class 3 is the Standard: While there were multiple classes, Class 3 DSC is now the highest-security and most widely required standard for almost all applications, including GST, ITR, MCA, and e-procurement portals.
- ⚡ The Process is Now Paperless: The most effective way to obtain a DSC is through a completely online, paperless process using Aadhaar eKYC, which includes mobile and video verification. This can often be completed in under 30 minutes.
- 📄 Core Documents: You will typically need your PAN card, Aadhaar card for eKYC, a passport-sized photo, and basic contact details to complete the application.
Understanding the Digital Signature Certificate (DSC)
Before diving into the 'how,' let's clarify the 'what.' A Digital Signature Certificate is more than just a digital image of your signature.
It's a cryptographic tool based on Public Key Infrastructure (PKI) technology. When you sign a document with a DSC, a unique digital fingerprint is created, which gets embedded into the document.
This process ensures three critical things:
- Authentication: It proves your identity as the signer, as the DSC is uniquely linked to you after a rigorous verification process.
- Integrity: It ensures the document has not been tampered with since it was signed. Any alteration would invalidate the signature.
- Non-repudiation: It prevents you from later denying that you signed the document, providing strong legal evidence.
-
It's important to distinguish between an electronic signature and a digital signature. While all digital signatures are a form of electronic signature, not all electronic signatures have the PKI-based security of a DSC.

Thanks to streamlined digital processes, obtaining a DSC is faster than ever. The most effective method is the paperless eKYC process.
Here's a breakdown of the steps involved.
Step 1: Choose a Licensed Certifying Authority (CA)
In India, DSCs are issued by licensed Certifying Authorities (CAs), who are regulated by the Controller of Certifying Authorities (CCA).
You cannot get a DSC directly from the government. You must go through one of these licensed CAs. Popular CAs include eMudhra, Capricorn, and Sify. You can find the complete, updated list on the official CCA website.
Step 2: Select Your DSC Type and Validity
On the CA's website, you will need to make a few selections:
- Certificate Class: Choose Class 3. This is the most secure and universally accepted class, now mandated for most purposes.
- Certificate Type: You'll typically see 'Signature' and 'Signature + Encryption'. For most filings (MCA, GST, ITR), 'Signature' is sufficient. The 'Encryption' combo is for securing data, often used in e-tendering.
- Validity: DSCs are typically available with a validity of 1, 2, or 3 years. Choose based on your long-term needs.
Step 3: Complete the Application and eKYC Verification
This is the most critical phase. The paperless method is the fastest.
Checklist for Paperless eKYC Application:
- Fill the Online Form: Enter your basic details, including Name, Address, PAN, and contact information.
- Aadhaar eKYC: Enter your Aadhaar number and the OTP sent to your registered mobile number. This automatically fetches your details and photo, eliminating the need to upload documents.
- Video Verification: You will be prompted to record a short video of yourself. You'll need to state your name, that you have applied for a DSC, and hold up your original PAN card and address proof to the camera. This is a mandatory security step.
- Mobile & Email Verification: Complete the final OTP verification for your provided mobile number and email address.
- Sign Documents Anywhere: Use legally binding electronic signatures on any device, without needing a physical USB token for every signature.
- Manage Workflows: Create templates, send documents for signature to multiple parties in a specific order, and track progress in real-time with a complete audit trail.
- Ensure Compliance: eSignly is compliant with global regulations like the ESIGN Act in the USA and eIDAS in the EU, and our signatures are legally recognized in India for a wide range of business agreements. We are also accredited with ISO 27001, SOC 2, and HIPAA for enterprise-grade security.
- Integrate with APIs: Automate your signing processes by integrating eSignly directly into your existing applications and software.
Step 4: Make the Payment
Pay the required fees through the CA's online portal using a credit card, debit card, net banking, or UPI. The cost typically ranges from ₹500 to ₹2500, depending on the validity and type of certificate.
Step 5: Download Your DSC
Once your application and verification are approved by the CA (which often happens within minutes to a few hours), you will receive an email and SMS with instructions to download your DSC.
You will need to install it onto a FIPS 140-2 Level 2 certified cryptographic USB token. Most CAs will ship this token to you if you don't already have one.
2025 Update: The Shift to Higher Security and Paperless Processes
The digital signature landscape in India continues to evolve towards greater security and user convenience. As of 2025, the government has effectively phased out lower-assurance Class 1 and Class 2 certificates for most business and legal purposes.
The industry-wide consolidation to Class 3 DSCs as the default standard reflects a commitment to robust, legally enforceable digital transactions.
Furthermore, the reliance on paperless eKYC based on Aadhaar is now the primary method for issuance. This not only accelerates the process from days to mere minutes but also significantly reduces the risk of identity fraud.
This move aligns with the broader Digital India initiative, emphasizing secure, scalable, and accessible digital infrastructure for all citizens and businesses. For anyone needing a DSC, embracing this digital-first approach is the most effective path forward.
Beyond the DSC: Integrating Digital Signatures into Your Workflow
Obtaining a DSC is a crucial compliance step, but its true power is unlocked when you integrate it into your daily document workflows.
A DSC stored on a USB token is perfect for government portal logins and filings, but what about signing contracts, invoices, or HR documents?
This is where platforms like eSignly come in. While your DSC serves as your high-assurance digital identity for specific government-mandated tasks, eSignly provides a comprehensive solution for all other business-related electronic signing needs.

Frequently Asked Questions
What is the difference between a Class 2 and Class 3 Digital Signature Certificate?
Historically, Class 2 DSCs were used for filings where the risk was moderate, like company and tax filings. Class 3 DSCs were for high-security transactions like e-tendering.
However, to standardize and enhance security, the CCA has mandated that Class 3 is now the required standard for almost all purposes. Class 3 involves a more rigorous identity verification process (including video verification) and offers the highest level of assurance.
How long does it take to get a DSC in India?
Using the paperless Aadhaar eKYC method, the entire process can be completed very quickly. After you fill the form and complete the mobile and video verification, a licensed Certifying Authority can approve and issue your DSC in as little as 15-30 minutes.
What is a USB Token and why do I need one for my DSC?
A USB token, also known as a crypto token, is a password-protected hardware device that looks like a pen drive. It is mandatory to store your DSC on a FIPS 140-2 Level 2 certified token.
This ensures that your private key is stored securely and cannot be exported, preventing misuse and providing a secure environment for creating digital signatures.
Can I use my Indian DSC internationally?
The legal recognition of a DSC issued in India depends on the laws of the other country. While the underlying technology (PKI) is global, its legal validity for contracts or government filings outside India is not guaranteed.
For international business agreements, a globally compliant electronic signature platform like eSignly, which adheres to laws like the US ESIGN Act and EU eIDAS regulation, is often a more suitable choice.
What should I do if I lose my DSC token?
If you lose your USB token, you must immediately contact the Certifying Authority (CA) from whom you purchased the DSC and request them to revoke the certificate.
This will prevent any potential misuse. Unfortunately, a DSC cannot be 'copied' or 'backed up'. You will need to apply for a new Digital Signature Certificate.
Ready to Move Beyond Compliance and Towards Efficiency?
Your DSC handles government filings, but what about the dozens of contracts, agreements, and approvals your business signs every week? Don't let your digital transformation stop at the bare minimum.
