What Is a Digital Signature Certificate (DSC)?
A Digital Signature Certificate (DSC) is an electronic credential issued by a government-licensed Certifying Authority (CA) that uniquely identifies the holder and is used to sign digital documents electronically. In India, DSCs are issued under the Information Technology Act, 2000 and are legally equivalent to a physical signature on a paper document.
DSCs are now mandatory or heavily preferred for a wide range of legal, financial, and government processes in India - including company incorporation and annual filings with the Ministry of Corporate Affairs (MCA), income tax return filing, RERA applications, government e-tendering, EPF and ESI filings, and various court-related digital processes.
DSCs are stored on a USB token (hardware security module) or can be cloud-based, and are protected by a PIN. They cannot be forged, replicated or misused without physical access to the token and the PIN.

Our Digital Signature Service - How We Help
We understand your use case - what portal or process requires the DSC, what class of DSC is needed, and whether you need an individual or organisation DSC.
We assist with the application to a licensed Certifying Authority (CA). Class 3 DSC (the most secure, required for MCA and e-tendering) involves Aadhaar-based or video-based KYC verification.
We guide you through identity verification using your Aadhaar, PAN, and passport photograph. For video-based KYC, we assist with the online verification process.
The DSC is downloaded to a USB cryptographic token. We set it up, test it, and explain how to use it for signing documents on the relevant portal.
If you need specific documents signed immediately (MCA forms, RERA forms, contracts), we assist with e-signing them using the DSC on the relevant portal at our office.
Classes of DSC Available
- Class 3 DSC (Individual) - Highest security level. Required for MCA filings, e-tendering, income tax (companies), RERA. Issued after KYC verification. Valid for 1 or 2 years.
- Class 3 DSC (Organisation) - For entities (companies, LLPs, firms) - includes organisation name along with individual signatory details. Required for company filings under MCA.
- DGFT DSC - Specifically for Directorate General of Foreign Trade (DGFT) portal for import-export related filings and IECF applications.
We advise on the correct class and type for your specific requirement before application, so you obtain the right DSC the first time.
Frequently Asked Questions
A digital signature (DSC) uses Public Key Infrastructure (PKI) cryptography - it is mathematically linked to the document content and the signer's unique certificate, making it tamper-evident and non-repudiable. An electronic signature (e-sign) is a broader term that includes typed names, scanned signatures, and Aadhaar OTP-based signatures. DSCs provide the highest level of legal security. For MCA, income tax (companies) and e-tendering, a DSC is specifically required, not just any e-signature.
With Aadhaar-based video KYC, a Class 3 DSC can typically be issued within 1 to 3 working days after successful KYC verification. The process involves an online video call with the Certifying Authority's representative for identity verification. With physical verification at a Registration Authority (RA) office, it may take slightly longer. We assist with all the steps to ensure the fastest possible issuance.
DSCs are typically valid for 1 year or 2 years from the date of issuance, depending on the package chosen at the time of application. Before expiry, the DSC must be renewed by applying for a fresh certificate. We can alert you before your DSC expires and assist with renewal.
Yes. A Class 3 Individual DSC can generally be used across multiple government portals - MCA21, Income Tax e-Filing, RERA, GeM, CPPP, and more. However, DGFT filings require a specific DGFT-class DSC. We verify compatibility with your specific portals before the application so you obtain the right type.
A DSC stored on a USB token is physically portable - you carry the token and the PIN. However, sharing your DSC with others is a serious security risk and is legally problematic - the signature on any document will legally bind you, and misuse of a DSC is an offence under the IT Act. Always keep your USB token and PIN secure and never share them.
Yes. If you have a DSC token but need assistance in e-signing a specific document or form on a government portal (MCA21 form, RERA application, etc.), you can visit our office with your DSC token and PIN and we will guide you through the signing process on the relevant portal.
